+		file.
+
+		This is a superset of FPGA states and fpga manager driver
+		states.  The fpga manager driver is walking through these steps
+		to get the FPGA into a known operating state.  It's a sequence,
+		though some steps may get skipped.  Valid FPGA states will vary
+		by manufacturer; this is a superset.
+
+		* unknown		= can't determine state
+		* power off		= FPGA power is off
+		* power up		= FPGA reports power is up
+		* reset			= FPGA held in reset state

+	    <para>The kernel demux API defines a driver-internal interface for
+	    registering low-level, hardware specific driver to a hardware
+	    independent demux layer. It is only of interest for Digital TV
+	    device driver writers. The header file for this API is named
+	    <constant>demux.h</constant> and located in
+	    <constant>drivers/media/dvb-core</constant>.</para>
+
+	<para>The demux API should be implemented for each demux in the
+	system. It is used to select the TS source of a demux and to manage
+	the demux resources. When the demux client allocates a resource via
+	the demux API, it receives a pointer to the API of that
+	resource.</para>
+	<para>Each demux receives its TS input from a DVB front-end or from
+	memory, as set via this demux API. In a system with more than one
+	front-end, the API can be used to select one of the DVB front-ends
+	as a TS source for a demux, unless this is fixed in the HW platform.
+	The demux API only controls front-ends regarding to their connections
+	with demuxes; the APIs used to set the other front-end parameters,
+	such as tuning, are not defined in this document.</para>
+	<para>The functions that implement the abstract interface demux should
+	be defined static or module private and registered to the Demux
+	core for external access. It is not necessary to implement every
+	function in the struct <constant>dmx_demux</constant>. For example,
+	a demux interface might support Section filtering, but not PES
+	filtering. The API client is expected to check the value of any
+	function pointer before calling the function: the value of NULL means
+	that the &#8220;function is not available&#8221;.</para>
+	<para>Whenever the functions of the demux API modify shared data,
+	the possibilities of lost update and race condition problems should
+	be addressed, e.g. by protecting parts of code with mutexes.</para>
+	<para>Note that functions called from a bottom half context must not
+	sleep. Even a simple memory allocation without using GFP_ATOMIC can
+	result in a kernel thread being put to sleep if swapping is needed.
+	For example, the Linux kernel calls the functions of a network device
+	interface from a bottom half context. Thus, if a demux API function
+	is called from network device code, the function must not sleep.
+	</para>
+    </sect1>
+
+    <section id="demux_callback_api">
+	<title>Demux Callback API</title>
+	<para>This kernel-space API comprises the callback functions that
+	deliver filtered data to the demux client. Unlike the other DVB
+	kABIs, these functions are provided by the client and called from
+	the demux code.</para>
+	<para>The function pointers of this abstract interface are not
+	packed into a structure as in the other demux APIs, because the
+	callback functions are registered and used independent of each
+	other. As an example, it is possible for the API client to provide
+	several callback functions for receiving TS packets and no
+	callbacks for PES packets or sections.</para>
+	<para>The functions that implement the callback API need not be
+	re-entrant: when a demux driver calls one of these functions,
+	the driver is not allowed to call the function again before
+	the original call returns. If a callback is triggered by a
+	hardware interrupt, it is recommended to use the Linux
+	&#8220;bottom half&#8221; mechanism or start a tasklet instead of
+	making the callback function call directly from a hardware
+	interrupt.</para>
+	<para>This mechanism is implemented by
+	<link linkend='API-dmx-ts-cb'>dmx_ts_cb()</link> and
+	<link linkend='API-dmx-section-cb'>dmx_section_cb()</link>.</para>

-<section id="demux_api">
-<title>Demux API</title>
-<para>The demux API should be implemented for each demux in the system. It is used to select
-the TS source of a demux and to manage the demux resources. When the demux
-client allocates a resource via the demux API, it receives a pointer to the API of that
-resource.
-</para>
-<para>Each demux receives its TS input from a DVB front-end or from memory, as set via the
-demux API. In a system with more than one front-end, the API can be used to select one of
-the DVB front-ends as a TS source for a demux, unless this is fixed in the HW platform. The
-demux API only controls front-ends regarding their connections with demuxes; the APIs
-used to set the other front-end parameters, such as tuning, are not defined in this
-document.
-</para>
-<para>The functions that implement the abstract interface demux should be defined static or
-module private and registered to the Demux Directory for external access. It is not necessary
-to implement every function in the demux_t struct, however (for example, a demux interface
-might support Section filtering, but not TS or PES filtering). The API client is expected to
-check the value of any function pointer before calling the function: the value of NULL means
-&#8220;function not available&#8221;.
-</para>
-<para>Whenever the functions of the demux API modify shared data, the possibilities of lost
-update and race condition problems should be addressed, e.g. by protecting parts of code with
-mutexes. This is especially important on multi-processor hosts.
-</para>
-<para>Note that functions called from a bottom half context must not sleep, at least in the 2.2.x
-kernels. Even a simple memory allocation can result in a kernel thread being put to sleep if
-swapping is needed. For example, the Linux kernel calls the functions of a network device
-interface from a bottom half context. Thus, if a demux API function is called from network
-device code, the function must not sleep.

-<title>Demux Callback API</title>
-<para>This kernel-space API comprises the callback functions that deliver filtered data to the
-demux client. Unlike the other APIs, these API functions are provided by the client and called
-from the demux code.
-</para>
-<para>The function pointers of this abstract interface are not packed into a structure as in the
-other demux APIs, because the callback functions are registered and used independent
-of each other. As an example, it is possible for the API client to provide several
-callback functions for receiving TS packets and no callbacks for PES packets or
-sections.
-</para>
-<para>The functions that implement the callback API need not be re-entrant: when a demux
-driver calls one of these functions, the driver is not allowed to call the function again before
-the original call returns. If a callback is triggered by a hardware interrupt, it is recommended
-to use the Linux &#8220;bottom half&#8221; mechanism or start a tasklet instead of making the callback
-function call directly from a hardware interrupt.

-Some of the device drivers used on keystone are re-used from that from

-   Add 'clk_ignore_unused' to the bootargs env variable in u-boot. Otherwise

+
+The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
+the main hardware sub system which forms the backbone of the Keystone
+multi-core Navigator. QMSS consist of queue managers, packed-data structure
+processors(PDSP), linking RAM, descriptor pools and infrastructure
+Packet DMA.
+The Queue Manager is a hardware module that is responsible for accelerating
+management of the packet queues. Packets are queued/de-queued by writing or
+reading descriptor address to a particular memory mapped location. The PDSPs
+perform QMSS related functions like accumulation, QoS, or event management.
+Linking RAM registers are used to link the descriptors which are stored in
+descriptor RAM. Descriptor RAM is configurable as internal or external memory.
+The QMSS driver manages the PDSP setups, linking RAM regions,
+queue pool management (allocation, push, pop and notify) and descriptor
+pool management.
+
+knav qmss driver provides a set of APIs to drivers to open/close qmss queues,
+allocate descriptor pools, map the descriptors, push/pop to queues etc. For
+details of the available APIs, please refers to include/linux/soc/ti/knav_qmss.h
+
+DT documentation is available at
+Documentation/devicetree/bindings/soc/ti/keystone-navigator-qmss.txt
+
+Accumulator QMSS queues using PDSP firmware
+============================================
+The QMSS PDSP firmware support accumulator channel that can monitor a single
+queue or multiple contiguous queues. drivers/soc/ti/knav_qmss_acc.c is the
+driver that interface with the accumulator PDSP. This configures
+accumulator channels defined in DTS (example in DT documentation) to monitor
+1 or 32 queues per channel. More description on the firmware is available in
+CPPI/QMSS Low Level Driver document (docs/CPPI_QMSS_LLD_SDS.pdf) at
+	git://git.ti.com/keystone-rtos/qmss-lld.git
+
+k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin firmware supports upto 48 accumulator
+channels. This firmware is available under ti-keystone folder of
+firmware.git at
+   git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
+
+To use copy the firmware image to lib/firmware folder of the initramfs or
+ubifs file system and provide a sym link to k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin
+in the file system and boot up the kernel. User would see
+
+ "firmware file ks2_qmss_pdsp_acc48.bin downloaded for PDSP"
+
+in the boot up log if loading of firmware to PDSP is successful.
+
+Use of accumulated queues requires the firmware image to be present in the
+file system. The driver doesn't acc queues to the supported queue range if
+PDSP is not running in the SoC. The API call fails if there is a queue open
+request to an acc queue and PDSP is not running. So make sure to copy firmware
+to file system before using these queue types.

+Block layer support for Persistent Reservations
+===============================================
+
+The Linux kernel supports a user space interface for simplified
+Persistent Reservations which map to block devices that support
+these (like SCSI). Persistent Reservations allow restricting
+access to block devices to specific initiators in a shared storage
+setup.
+
+This document gives a general overview of the support ioctl commands.
+For a more detailed reference please refer the the SCSI Primary
+Commands standard, specifically the section on Reservations and the
+"PERSISTENT RESERVE IN" and "PERSISTENT RESERVE OUT" commands.
+
+All implementations are expected to ensure the reservations survive
+a power loss and cover all connections in a multi path environment.
+These behaviors are optional in SPC but will be automatically applied
+by Linux.
+
+
+The following types of reservations are supported:
+--------------------------------------------------
+
+ - PR_WRITE_EXCLUSIVE
+
+	Only the initiator that owns the reservation can write to the
+	device.  Any initiator can read from the device.
+
+ - PR_EXCLUSIVE_ACCESS
+
+	Only the initiator that owns the reservation can access the
+	device.
+
+ - PR_WRITE_EXCLUSIVE_REG_ONLY
+
+	Only initiators with a registered key can write to the device,
+	Any initiator can read from the device.
+
+ - PR_EXCLUSIVE_ACCESS_REG_ONLY
+
+	Only initiators with a registered key can access the device.
+
+ - PR_WRITE_EXCLUSIVE_ALL_REGS
+
+	Only initiators with a registered key can write to the device,
+	Any initiator can read from the device.
+	All initiators with a registered key are considered reservation
+	holders.
+	Please reference the SPC spec on the meaning of a reservation
+	holder if you want to use this type. 
+
+ - PR_EXCLUSIVE_ACCESS_ALL_REGS
+
+	Only initiators with a registered key can access the device.
+	All initiators with a registered key are considered reservation
+	holders.
+	Please reference the SPC spec on the meaning of a reservation
+	holder if you want to use this type. 
+
+
+The following ioctl are supported:
+----------------------------------
+
+1. IOC_PR_REGISTER
+
+This ioctl command registers a new reservation if the new_key argument
+is non-null.  If no existing reservation exists old_key must be zero,
+if an existing reservation should be replaced old_key must contain
+the old reservation key.
+
+If the new_key argument is 0 it unregisters the existing reservation passed
+in old_key.
+
+
+2. IOC_PR_RESERVE
+
+This ioctl command reserves the device and thus restricts access for other
+devices based on the type argument.  The key argument must be the existing
+reservation key for the device as acquired by the IOC_PR_REGISTER,
+IOC_PR_REGISTER_IGNORE, IOC_PR_PREEMPT or IOC_PR_PREEMPT_ABORT commands.
+
+
+3. IOC_PR_RELEASE
+
+This ioctl command releases the reservation specified by key and flags
+and thus removes any access restriction implied by it.
+
+
+4. IOC_PR_PREEMPT
+
+This ioctl command releases the existing reservation referred to by
+old_key and replaces it with a a new reservation of type for the
+reservation key new_key.
+
+
+5. IOC_PR_PREEMPT_ABORT
+
+This ioctl command works like IOC_PR_PREEMPT except that it also aborts
+any outstanding command sent over a connection identified by old_key.
+
+6. IOC_PR_CLEAR
+
+This ioctl command unregisters both key and any other reservation key
+registered with the device and drops any existing reservation.
+
+
+Flags
+-----
+
+All the ioctls have a flag field.  Currently only one flag is supported:
+
+ - PR_FL_IGNORE_KEY
+
+	Ignore the existing reservation key.  This is commonly supported for
+	IOC_PR_REGISTER, and some implementation may support the flag for
+	IOC_PR_RESERVE.
+
+For all unknown flags the kernel will return -EOPNOTSUPP.

+by Linux to initiate various system control and power operations.
+
+Required properties:
+
+- compatible : should be "arm,scpi"
+- mboxes: List of phandle and mailbox channel specifiers
+	  All the channels reserved by remote SCP firmware for use by
+	  SCPI message protocol should be specified in any order

+	  processors using these mailboxes for IPC, one for each mailbox
+	  SHM can be any memory reserved for the purpose of this communication
+	  between the processors.
+
+See Documentation/devicetree/bindings/mailbox/mailbox.txt
+for more details about the generic mailbox controller and

+
+Clock bindings for the clocks based on SCPI Message Protocol
+------------------------------------------------------------
+
+This binding uses the common clock binding[1].
+

+Required properties:
+- compatible : should be "arm,scpi-clocks"
+	       All the clocks provided by SCP firmware via SCPI message
+	       protocol much be listed as sub-nodes under this node.
+
+Sub-nodes
+=========
+Required properties:
+- compatible : shall include one of the following
+	"arm,scpi-dvfs-clocks" - all the clocks that are variable and index based.
+		These clocks don't provide an entire range of values between the
+		limits but only discrete points within the range. The firmware
+		provides the mapping for each such operating frequency and the
+		index associated with it. The firmware also manages the
+		voltage scaling appropriately with the clock scaling.
+	"arm,scpi-variable-clocks" - all the clocks that are variable and provide full
+		range within the specified range. The firmware provides the
+		range of values within a specified range.
+
+Other required properties for all clocks(all from common clock binding):
+- #clock-cells : Should be 1. Contains the Clock ID value used by SCPI commands.
+- clock-output-names : shall be the corresponding names of the outputs.
+- clock-indices: The identifying number for the clocks(i.e.clock_id) in the
+	node. It can be non linear and hence provide the mapping of identifiers
+	into the clock-output-names array.
+
+SRAM and Shared Memory for SCPI
+-------------------------------
+
+A small area of SRAM is reserved for SCPI communication between application
+processors and SCP.
+
+Required properties:
+- compatible : should be "arm,juno-sram-ns" for Non-secure SRAM on Juno
+
+The rest of the properties should follow the generic mmio-sram description
+found in ../../misc/sysram.txt
+
+Each sub-node represents the reserved area for SCPI.
+
+Required sub-node properties:
+- reg : The base offset and size of the reserved area with the SRAM
+- compatible : should be "arm,juno-scp-shmem" for Non-secure SRAM based
+	       shared memory on Juno platforms
+
+Sensor bindings for the sensors based on SCPI Message Protocol
+--------------------------------------------------------------
+SCPI provides an API to access the various sensors on the SoC.
+
+Required properties:
+- compatible : should be "arm,scpi-sensors".
+- #thermal-sensor-cells: should be set to 1. This property follows the
+			 thermal device tree bindings[2].
+
+			 Valid cell values are raw identifiers (Sensor
+			 ID) as used by the firmware. Refer to
+			 platform documentation for your
+			 implementation for the IDs to use. For Juno
+			 R0 and Juno R1 refer to [3].

+
+The first consumer in the example is cpu@0 and it has '0' as the clock
+specifier which points to the first entry in the output clocks of
+scpi_dvfs i.e. "atlclk".
+
+Similarly the second example is hdlcd@7ff60000 and it has pxlclk1 as input
+clock. '4' in the clock specifier here points to the second entry
+in the output clocks of scpi_clocks  i.e. "pxlclk1"
+
+The thermal-sensors property in the soc_thermal node uses the
+temperature sensor provided by SCP firmware to setup a thermal
+zone. The ID "3" is the sensor identifier for the temperature sensor
+as used by the firmware.

+UniPhier outer cache controller
+
+UniPhier SoCs are integrated with a full-custom outer cache controller system.
+All of them have a level 2 cache controller, and some have a level 3 cache
+controller as well.
+
+Required properties:
+- compatible: should be "socionext,uniphier-system-cache"
+- reg: offsets and lengths of the register sets for the device.  It should
+  contain 3 regions: control register, revision register, operation register,
+  in this order.
+- cache-unified: specifies the cache is a unified cache.
+- cache-size: specifies the size in bytes of the cache
+- cache-sets: specifies the number of associativity sets of the cache
+- cache-line-size: specifies the line size in bytes
+- cache-level: specifies the level in the cache hierarchy.  The value should
+  be 2 for L2 cache, 3 for L3 cache, etc.
+
+Optional properties:
+- next-level-cache: phandle to the next level cache if present.  The next level
+  cache should be also compatible with "socionext,uniphier-system-cache".
+
+The L2 cache must exist to use the L3 cache; the cache hierarchy must be
+indicated correctly with "next-level-cache" properties.
+
+Example 1 (system with L2):
+	l2: l2-cache@500c0000 {
+		compatible = "socionext,uniphier-system-cache";

+		cache-size = <0x80000>;
+		cache-sets = <256>;
+		cache-line-size = <128>;
+		cache-level = <2>;

+Allwinner Reduced Serial Bus (RSB) controller
+
+The RSB controller found on later Allwinner SoCs is an SMBus like 2 wire

+for the controller itself, and child nodes representing the slave devices.
+

+ - compatible      : Shall be "allwinner,sun8i-a23-rsb".

+ - clocks          : The gate clk associated to the RSB controller.
+ - resets          : The reset line associated to the RSB controller.
+ - #address-cells  : shall be 1
+ - #size-cells     : shall be 0
+
+Optional properties :
+
+ - clock-frequency : Desired RSB bus clock frequency in Hz. Maximum is 20MHz.
+		     If not set this defaults to 3MHz.
+
+Child nodes:
+
+An RSB controller node can contain zero or more child nodes representing
+slave devices on the bus.  Child 'reg' properties should contain the slave
+device's hardware address. The hardware address is hardwired in the device,
+which can normally be found in the datasheet.
+
+Example:
+

+This binding uses the common clock binding:
+    Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The CPRMAN clock controller generates clocks in the audio power domain
+of the BCM2835.  There is a level of PLLs deriving from an external
+oscillator, a level of PLL dividers that produce channels off of the
+few PLLs, and a level of mostly-generic clock generators sourcing from
+the PLL channels.  Most other hardware components source from the
+clock generators, but a few (like the ARM or HDMI) will source from
+the PLL dividers directly.

+* Renesas Clock Pulse Generator / Module Standby and Software Reset
+
+On Renesas ARM SoCs (SH/R-Mobile, R-Car, RZ), the CPG (Clock Pulse Generator)
+and MSSR (Module Standby and Software Reset) blocks are intimately connected,
+and share the same register block.
+
+They provide the following functionalities:
+  - The CPG block generates various core clocks,
+  - The MSSR block provides two functions:
+      1. Module Standby, providing a Clock Domain to control the clock supply
+	 to individual SoC devices,
+      2. Reset Control, to perform a software reset of individual SoC devices.
+
+Required Properties:
+  - compatible: Must be one of:
+      - "renesas,r8a7795-cpg-mssr" for the r8a7795 SoC
+
+  - reg: Base address and length of the memory resource used by the CPG/MSSR
+    block
+
+  - clocks: References to external parent clocks, one entry for each entry in
+    clock-names
+  - clock-names: List of external parent clock names. Valid names are:
+      - "extal" (r8a7795)
+      - "extalr" (r8a7795)
+
+  - #clock-cells: Must be 2
+      - For CPG core clocks, the two clock specifier cells must be "CPG_CORE"
+	and a core clock reference, as defined in
+	<dt-bindings/clock/*-cpg-mssr.h>.
+      - For module clocks, the two clock specifier cells must be "CPG_MOD" and
+	a module number, as defined in the datasheet.
+
+  - #power-domain-cells: Must be 0
+      - SoC devices that are part of the CPG/MSSR Clock Domain and can be
+	power-managed through Module Standby should refer to the CPG device
+	node in their "power-domains" property, as documented by the generic PM
+	Domain bindings in
+	Documentation/devicetree/bindings/power/power_domain.txt.

@@ -118,6 +131,30 @@ Every GPIO controller node must contain both an empty "gpio-controller"
 property, and a #gpio-cells integer property, which indicates the number of
 cells in a gpio-specifier.
 
+Optionally, a GPIO controller may have a "ngpios" property. This property
+indicates the number of in-use slots of available slots for GPIOs. The
+typical example is something like this: the hardware register is 32 bits
+wide, but only 18 of the bits have a physical counterpart. The driver is
+generally written so that all 32 bits can be used, but the IP block is reused
+in a lot of designs, some using all 32 bits, some using 18 and some using
+12. In this case, setting "ngpios = <18>;" informs the driver that only the
+first 18 GPIOs, at local offset 0 .. 17, are in use.
+
+If these GPIOs do not happen to be the first N GPIOs at offset 0...N-1, an
+additional bitmask is needed to specify which GPIOs are actually in use,
+and which are dummies. The bindings for this case has not yet been
+specified, but should be specified if/when such hardware appears.

+Imagination University Program MIPSfpga
+=======================================
+
+Under the Imagination University Program, a microAptiv UP core has been
+released for academic usage.
+
+As we are dealing with a MIPS core instantiated on an FPGA, specifications
+are fluid and can be varied in RTL.
+
+This binding document is provided as baseline guidance for the example
+project provided by IMG.
+
+The example project runs on the Nexys4DDR board by Digilent powered by
+the ARTIX-7 FPGA by Xilinx.
+
+Relevant details about the example project and the Nexys4DDR board:
+
+- microAptiv UP core m14Kc
+- 50MHz clock speed
+- 128Mbyte DDR RAM	at 0x0000_0000
+- 8Kbyte RAM		at 0x1000_0000
+- axi_intc		at 0x1020_0000
+- axi_uart16550		at 0x1040_0000
+- axi_gpio		at 0x1060_0000
+- axi_i2c		at 0x10A0_0000
+- custom_gpio		at 0x10C0_0000
+- axi_ethernetlite	at 0x10E0_0000
+- 8Kbyte BootRAM	at 0x1FC0_0000
+
+Required properties:
+--------------------
+ - compatible: Must include "digilent,nexys4ddr","img,xilfpga".
+
+CPU nodes:
+----------
+A "cpus" node is required.  Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Required properties:
+ - device_type: Must be "cpu".
+ - compatible: Must be "mips,m14Kc".
+ - reg: Must be <0>.
+ - clocks: phandle to ext clock for fixed-clock received by MIPS core.
+
+Example:
+
+	compatible = "img,xilfpga","digilent,nexys4ddr";
+	cpus {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		cpu0: cpu@0 {
+			device_type = "cpu";
+			compatible = "mips,m14Kc";
+			reg = <0>;
+			clocks	= <&ext>;
+		};
+	};
+
+	ext: ext {
+		compatible = "fixed-clock";
+		#clock-cells = <0>;
+		clock-frequency = <50000000>;
+	};
+
+Boot protocol:
+--------------
+
+The BootRAM is a writeable "RAM" in FPGA at 0x1FC0_0000.
+This is for easy reprogrammibility via JTAG.
+
+The BootRAM initializes the cache and the axi_uart peripheral.
+
+DDR initialization is already handled by a HW IP block.
+
+When the example project bitstream is loaded, the cpu_reset button
+needs to be pressed.
+
+The bootram initializes the cache and axi_uart.
+Then outputs MIPSFPGA\n\r on the serial port on the Nexys4DDR board.
+
+At this point, the board is ready to load the Linux kernel
+vmlinux file via JTAG.

+Freescale's NAND flash controller (NFC)
+
+This variant of the Freescale NAND flash controller (NFC) can be found on
+Vybrid (vf610), MPC5125, MCF54418 and Kinetis K70.
+
+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc".
+- reg: address range of the NFC.
+- interrupts: interrupt of the NFC.
+- #address-cells: shall be set to 1. Encode the nand CS.
+- #size-cells : shall be set to 0.
+- assigned-clocks: main clock from the SoC, for Vybrid <&clks VF610_CLK_NFC>;
+- assigned-clock-rates: The NAND bus timing is derived from this clock
+    rate and should not exceed maximum timing for any NAND memory chip
+    in a board stuffing. Typical NAND memory timings derived from this
+    clock are found in the SoC hardware reference manual. Furthermore,
+    there might be restrictions on maximum rates when using hardware ECC.
+
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+  representing partitions.
+
+Required children nodes:
+Children nodes represent the available nand chips. Currently the driver can
+only handle one NAND chip.

+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc-cs".
+- nand-bus-width: see nand.txt
+- nand-ecc-mode: see nand.txt

+This document describes the generic device tree binding for describing the
+relationship between PCI devices and MSI controllers.
+
+Each PCI device under a root complex is uniquely identified by its Requester ID
+(AKA RID). A Requester ID is a triplet of a Bus number, Device number, and
+Function number.
+
+For the purpose of this document, when treated as a numeric value, a RID is
+formatted such that:
+
+* Bits [15:8] are the Bus number.
+* Bits [7:3] are the Device number.
+* Bits [2:0] are the Function number.
+* Any other bits required for padding must be zero.
+
+MSIs may be distinguished in part through the use of sideband data accompanying
+writes. In the case of PCI devices, this sideband data may be derived from the
+Requester ID. A mechanism is required to associate a device with both the MSI
+controllers it can address, and the sideband data that will be associated with
+its writes to those controllers.
+
+For generic MSI bindings, see
+Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+
+PCI root complex
+================
+
+Optional properties
+-------------------
+
+- msi-map: Maps a Requester ID to an MSI controller and associated
+  msi-specifier data. The property is an arbitrary number of tuples of
+  (rid-base,msi-controller,msi-base,length), where:
+
+  * rid-base is a single cell describing the first RID matched by the entry.
+
+  * msi-controller is a single phandle to an MSI controller
+
+  * msi-base is an msi-specifier describing the msi-specifier produced for the
+    first RID matched by the entry.
+
+  * length is a single cell describing how many consecutive RIDs are matched
+    following the rid-base.
+
+  Any RID r in the interval [rid-base, rid-base + length) is associated with
+  the listed msi-controller, with the msi-specifier (r - rid-base + msi-base).
+
+- msi-map-mask: A mask to be applied to each Requester ID prior to being mapped
+  to an msi-specifier per the msi-map property.
+
+- msi-parent: Describes the MSI parent of the root complex itself. Where
+  the root complex and MSI controller do not pass sideband data with MSI
+  writes, this property may be used to describe the MSI controller(s)
+  used by PCI devices under the root complex, if defined as such in the
+  binding for the root complex.
+
+

+Specifying wakeup capability for devices
+============================================

+Any device nodes
+----------------
+Nodes that describe devices which has wakeup capability must contain an
+"wakeup-source" boolean property.
+
+Also, if device is marked as a wakeup source, then all the primary
+interrupt(s) can be used as wakeup interrupt(s).
+
+However if the devices have dedicated interrupt as the wakeup source
+then they need to specify/identify the same using device specific
+interrupt name. In such cases only that interrupt can be used as wakeup
+interrupt.

+Written by Neil Brown with help from Al Viro and Jon Corbet.
+
+Introduction
+------------
+
+The most obvious aspect of pathname lookup, which very little
+exploration is needed to discover, is that it is complex.  There are
+many rules, special cases, and implementation alternatives that all
+combine to confuse the unwary reader.  Computer science has long been
+acquainted with such complexity and has tools to help manage it.  One
+tool that we will make extensive use of is "divide and conquer".  For
+the early parts of the analysis we will divide off symlinks - leaving
+them until the final part.  Well before we get to symlinks we have
+another major division based on the VFS's approach to locking which
+will allow us to review "REF-walk" and "RCU-walk" separately.  But we
+are getting ahead of ourselves.  There are some important low level
+distinctions we need to clarify first.
+
+There are two sorts of ...
+--------------------------
+
+[`openat()`]: http://man7.org/linux/man-pages/man2/openat.2.html
+
+Pathnames (sometimes "file names"), used to identify objects in the
+filesystem, will be familiar to most readers.  They contain two sorts
+of elements: "slashes" that are sequences of one or more "`/`"
+characters, and "components" that are sequences of one or more
+non-"`/`" characters.  These form two kinds of paths.  Those that
+start with slashes are "absolute" and start from the filesystem root.
+The others are "relative" and start from the current directory, or
+from some other location specified by a file descriptor given to a
+"xxx`at`" system call such as "[`openat()`]".
+
+[`execveat()`]: http://man7.org/linux/man-pages/man2/execveat.2.html
+
+It is tempting to describe the second kind as starting with a
+component, but that isn't always accurate: a pathname can lack both
+slashes and components, it can be empty, in other words.  This is
+generally forbidden in POSIX, but some of those "xxx`at`" system calls
+in Linux permit it when the `AT_EMPTY_PATH` flag is given.  For
+example, if you have an open file descriptor on an executable file you
+can execute it by calling [`execveat()`] passing the file descriptor,
+an empty path, and the `AT_EMPTY_PATH` flag.
+
+These paths can be divided into two sections: the final component and
+everything else.  The "everything else" is the easy bit.  In all cases
+it must identify a directory that already exists, otherwise an error
+such as `ENOENT` or `ENOTDIR` will be reported.
+
+The final component is not so simple.  Not only do different system
+calls interpret it quite differently (e.g. some create it, some do
+not), but it might not even exist: neither the empty pathname nor the
+pathname that is just slashes have a final component.  If it does
+exist, it could be "`.`" or "`..`" which are handled quite differently
+from other components.
+
+[POSIX]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_12
+
+If a pathname ends with a slash, such as "`/tmp/foo/`" it might be
+tempting to consider that to have an empty final component.  In many
+ways that would lead to correct results, but not always.  In
+particular, `mkdir()` and `rmdir()` each create or remove a directory named
+by the final component, and they are required to work with pathnames
+ending in "`/`".  According to [POSIX]
+
+> A pathname that contains at least one non- &lt;slash> character and
+> that ends with one or more trailing &lt;slash> characters shall not
+> be resolved successfully unless the last pathname component before
+> the trailing <slash> characters names an existing directory or a
+> directory entry that is to be created for a directory immediately
+> after the pathname is resolved.
+
+The Linux pathname walking code (mostly in `fs/namei.c`) deals with
+all of these issues: breaking the path into components, handling the
+"everything else" quite separately from the final component, and
+checking that the trailing slash is not used where it isn't
+permitted.  It also addresses the important issue of concurrent
+access.
+
+While one process is looking up a pathname, another might be making
+changes that affect that lookup.  One fairly extreme case is that if
+"a/b" were renamed to "a/c/b" while another process were looking up
+"a/b/..", that process might successfully resolve on "a/c".
+Most races are much more subtle, and a big part of the task of
+pathname lookup is to prevent them from having damaging effects.  Many
+of the possible races are seen most clearly in the context of the
+"dcache" and an understanding of that is central to understanding
+pathname lookup.
+
+More than just a cache.
+-----------------------
+
+The "dcache" caches information about names in each filesystem to
+make them quickly available for lookup.  Each entry (known as a
+"dentry") contains three significant fields: a component name, a
+pointer to a parent dentry, and a pointer to the "inode" which
+contains further information about the object in that parent with
+the given name.  The inode pointer can be `NULL` indicating that the
+name doesn't exist in the parent.  While there can be linkage in the
+dentry of a directory to the dentries of the children, that linkage is
+not used for pathname lookup, and so will not be considered here.
+
+The dcache has a number of uses apart from accelerating lookup.  One
+that will be particularly relevant is that it is closely integrated
+with the mount table that records which filesystem is mounted where.
+What the mount table actually stores is which dentry is mounted on top
+of which other dentry.
+
+When considering the dcache, we have another of our "two types"
+distinctions: there are two types of filesystems.
+
+Some filesystems ensure that the information in the dcache is always
+completely accurate (though not necessarily complete).  This can allow
+the VFS to determine if a particular file does or doesn't exist
+without checking with the filesystem, and means that the VFS can
+protect the filesystem against certain races and other problems.
+These are typically "local" filesystems such as ext3, XFS, and Btrfs.
+
+Other filesystems don't provide that guarantee because they cannot.
+These are typically filesystems that are shared across a network,
+whether remote filesystems like NFS and 9P, or cluster filesystems
+like ocfs2 or cephfs.  These filesystems allow the VFS to revalidate
+cached information, and must provide their own protection against
+awkward races.  The VFS can detect these filesystems by the
+`DCACHE_OP_REVALIDATE` flag being set in the dentry.
+
+REF-walk: simple concurrency management with refcounts and spinlocks
+--------------------------------------------------------------------
+
+With all of those divisions carefully classified, we can now start
+looking at the actual process of walking along a path.  In particular
+we will start with the handling of the "everything else" part of a
+pathname, and focus on the "REF-walk" approach to concurrency
+management.  This code is found in the `link_path_walk()` function, if
+you ignore all the places that only run when "`LOOKUP_RCU`"
+(indicating the use of RCU-walk) is set.
+
+[Meet the Lockers]: https://lwn.net/Articles/453685/
+
+REF-walk is fairly heavy-handed with locks and reference counts.  Not
+as heavy-handed as in the old "big kernel lock" days, but certainly not
+afraid of taking a lock when one is needed.  It uses a variety of
+different concurrency controls.  A background understanding of the
+various primitives is assumed, or can be gleaned from elsewhere such
+as in [Meet the Lockers].
+
+The locking mechanisms used by REF-walk include:
+
+### dentry->d_lockref ###
+
+This uses the lockref primitive to provide both a spinlock and a
+reference count.  The special-sauce of this primitive is that the
+conceptual sequence "lock; inc_ref; unlock;" can often be performed
+with a single atomic memory operation.
+
+Holding a reference on a dentry ensures that the dentry won't suddenly
+be freed and used for something else, so the values in various fields
+will behave as expected.  It also protects the `->d_inode` reference
+to the inode to some extent.
+
+The association between a dentry and its inode is fairly permanent.
+For example, when a file is renamed, the dentry and inode move
+together to the new location.  When a file is created the dentry will
+initially be negative (i.e. `d_inode` is `NULL`), and will be assigned
+to the new inode as part of the act of creation.
+
+When a file is deleted, this can be reflected in the cache either by
+setting `d_inode` to `NULL`, or by removing it from the hash table
+(described shortly) used to look up the name in the parent directory.
+If the dentry is still in use the second option is used as it is
+perfectly legal to keep using an open file after it has been deleted
+and having the dentry around helps.  If the dentry is not otherwise in
+use (i.e. if the refcount in `d_lockref` is one), only then will
+`d_inode` be set to `NULL`.  Doing it this way is more efficient for a
+very common case.
+
+So as long as a counted reference is held to a dentry, a non-`NULL` `->d_inode`
+value will never be changed.
+
+### dentry->d_lock ###
+
+`d_lock` is a synonym for the spinlock that is part of `d_lockref` above.
+For our purposes, holding this lock protects against the dentry being
+renamed or unlinked.  In particular, its parent (`d_parent`), and its
+name (`d_name`) cannot be changed, and it cannot be removed from the
+dentry hash table.
+
+When looking for a name in a directory, REF-walk takes `d_lock` on
+each candidate dentry that it finds in the hash table and then checks
+that the parent and name are correct.  So it doesn't lock the parent
+while searching in the cache; it only locks children.
+
+When looking for the parent for a given name (to handle "`..`"),
+REF-walk can take `d_lock` to get a stable reference to `d_parent`,
+but it first tries a more lightweight approach.  As seen in
+`dget_parent()`, if a reference can be claimed on the parent, and if
+subsequently `d_parent` can be seen to have not changed, then there is
+no need to actually take the lock on the child.
+
+### rename_lock ###
+
+Looking up a given name in a given directory involves computing a hash
+from the two values (the name and the dentry of the directory),
+accessing that slot in a hash table, and searching the linked list
+that is found there.
+
+When a dentry is renamed, the name and the parent dentry can both
+change so the hash will almost certainly change too.  This would move the
+dentry to a different chain in the hash table.  If a filename search
+happened to be looking at a dentry that was moved in this way,
+it might end up continuing the search down the wrong chain,
+and so miss out on part of the correct chain.
+
+The name-lookup process (`d_lookup()`) does _not_ try to prevent this
+from happening, but only to detect when it happens.
+`rename_lock` is a seqlock that is updated whenever any dentry is
+renamed.  If `d_lookup` finds that a rename happened while it
+unsuccessfully scanned a chain in the hash table, it simply tries
+again.
+
+### inode->i_mutex ###
+
+`i_mutex` is a mutex that serializes all changes to a particular
+directory.  This ensures that, for example, an `unlink()` and a `rename()`
+cannot both happen at the same time.  It also keeps the directory
+stable while the filesystem is asked to look up a name that is not
+currently in the dcache.
+
+This has a complementary role to that of `d_lock`: `i_mutex` on a
+directory protects all of the names in that directory, while `d_lock`
+on a name protects just one name in a directory.  Most changes to the
+dcache hold `i_mutex` on the relevant directory inode and briefly take
+`d_lock` on one or more the dentries while the change happens.  One
+exception is when idle dentries are removed from the dcache due to
+memory pressure.  This uses `d_lock`, but `i_mutex` plays no role.
+
+The mutex affects pathname lookup in two distinct ways.  Firstly it
+serializes lookup of a name in a directory.  `walk_component()` uses
+`lookup_fast()` first which, in turn, checks to see if the name is in the cache,
+using only `d_lock` locking.  If the name isn't found, then `walk_component()`
+falls back to `lookup_slow()` which takes `i_mutex`, checks again that
+the name isn't in the cache, and then calls in to the filesystem to get a
+definitive answer.  A new dentry will be added to the cache regardless of
+the result.
+
+Secondly, when pathname lookup reaches the final component, it will
+sometimes need to take `i_mutex` before performing the last lookup so
+that the required exclusion can be achieved.  How path lookup chooses
+to take, or not take, `i_mutex` is one of the
+issues addressed in a subsequent section.
+
+### mnt->mnt_count ###
+
+`mnt_count` is a per-CPU reference counter on "`mount`" structures.
+Per-CPU here means that incrementing the count is cheap as it only
+uses CPU-local memory, but checking if the count is zero is expensive as
+it needs to check with every CPU.  Taking a `mnt_count` reference
+prevents the mount structure from disappearing as the result of regular
+unmount operations, but does not prevent a "lazy" unmount.  So holding
+`mnt_count` doesn't ensure that the mount remains in the namespace and,
+in particular, doesn't stabilize the link to the mounted-on dentry.  It
+does, however, ensure that the `mount` data structure remains coherent,
+and it provides a reference to the root dentry of the mounted
+filesystem.  So a reference through `->mnt_count` provides a stable
+reference to the mounted dentry, but not the mounted-on dentry.
+
+### mount_lock ###
+
+`mount_lock` is a global seqlock, a bit like `rename_lock`.  It can be used to
+check if any change has been made to any mount points.
+
+While walking down the tree (away from the root) this lock is used when
+crossing a mount point to check that the crossing was safe.  That is,
+the value in the seqlock is read, then the code finds the mount that
+is mounted on the current directory, if there is one, and increments
+the `mnt_count`.  Finally the value in `mount_lock` is checked against
+the old value.  If there is no change, then the crossing was safe.  If there
+was a change, the `mnt_count` is decremented and the whole process is
+retried.
+
+When walking up the tree (towards the root) by following a ".." link,
+a little more care is needed.  In this case the seqlock (which
+contains both a counter and a spinlock) is fully locked to prevent
+any changes to any mount points while stepping up.  This locking is
+needed to stabilize the link to the mounted-on dentry, which the
+refcount on the mount itself doesn't ensure.
+
+### RCU ###
+
+Finally the global (but extremely lightweight) RCU read lock is held
+from time to time to ensure certain data structures don't get freed
+unexpectedly.
+
+In particular it is held while scanning chains in the dcache hash
+table, and the mount point hash table.
+
+Bringing it together with `struct nameidata`
+--------------------------------------------
+
+[First edition Unix]: http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/u2.s
+
+Throughout the process of walking a path, the current status is stored
+in a `struct nameidata`, "namei" being the traditional name - dating
+all the way back to [First Edition Unix] - of the function that
+converts a "name" to an "inode".  `struct nameidata` contains (among
+other fields):
+
+### `struct path path` ###
+
+A `path` contains a `struct vfsmount` (which is
+embedded in a `struct mount`) and a `struct dentry`.  Together these
+record the current status of the walk.  They start out referring to the
+starting point (the current working directory, the root directory, or some other
+directory identified by a file descriptor), and are updated on each
+step.  A reference through `d_lockref` and `mnt_count` is always
+held.
+
+### `struct qstr last` ###
+
+This is a string together with a length (i.e. _not_ `nul` terminated)
+that is the "next" component in the pathname.
+
+### `int last_type` ###
+
+This is one of `LAST_NORM`, `LAST_ROOT`, `LAST_DOT`, `LAST_DOTDOT`, or
+`LAST_BIND`.  The `last` field is only valid if the type is
+`LAST_NORM`.  `LAST_BIND` is used when following a symlink and no
+components of the symlink have been processed yet.  Others should be
+fairly self-explanatory.
+
+### `struct path root` ###
+
+This is used to hold a reference to the effective root of the
+filesystem.  Often that reference won't be needed, so this field is
+only assigned the first time it is used, or when a non-standard root
+is requested.  Keeping a reference in the `nameidata` ensures that
+only one root is in effect for the entire path walk, even if it races
+with a `chroot()` system call.
+
+The root is needed when either of two conditions holds: (1) either the
+pathname or a symbolic link starts with a "'/'", or (2) a "`..`"
+component is being handled, since "`..`" from the root must always stay
+at the root.  The value used is usually the current root directory of
+the calling process.  An alternate root can be provided as when
+`sysctl()` calls `file_open_root()`, and when NFSv4 or Btrfs call
+`mount_subtree()`.  In each case a pathname is being looked up in a very
+specific part of the filesystem, and the lookup must not be allowed to
+escape that subtree.  It works a bit like a local `chroot()`.
+
+Ignoring the handling of symbolic links, we can now describe the
+"`link_path_walk()`" function, which handles the lookup of everything
+except the final component as:
+
+>  Given a path (`name`) and a nameidata structure (`nd`), check that the
+>  current directory has execute permission and then advance `name`
+>  over one component while updating `last_type` and `last`.  If that
+>  was the final component, then return, otherwise call
+>  `walk_component()` and repeat from the top.
+
+`walk_component()` is even easier.  If the component is `LAST_DOTS`,
+it calls `handle_dots()` which does the necessary locking as already
+described.  If it finds a `LAST_NORM` component it first calls
+"`lookup_fast()`" which only looks in the dcache, but will ask the
+filesystem to revalidate the result if it is that sort of filesystem.
+If that doesn't get a good result, it calls "`lookup_slow()`" which
+takes the `i_mutex`, rechecks the cache, and then asks the filesystem
+to find a definitive answer.  Each of these will call
+`follow_managed()` (as described below) to handle any mount points.
+
+In the absence of symbolic links, `walk_component()` creates a new
+`struct path` containing a counted reference to the new dentry and a
+reference to the new `vfsmount` which is only counted if it is
+different from the previous `vfsmount`.  It then calls
+`path_to_nameidata()` to install the new `struct path` in the
+`struct nameidata` and drop the unneeded references.
+
+This "hand-over-hand" sequencing of getting a reference to the new
+dentry before dropping the reference to the previous dentry may
+seem obvious, but is worth pointing out so that we will recognize its
+analogue in the "RCU-walk" version.
+
+Handling the final component.
+-----------------------------
+
+`link_path_walk()` only walks as far as setting `nd->last` and
+`nd->last_type` to refer to the final component of the path.  It does
+not call `walk_component()` that last time.  Handling that final
+component remains for the caller to sort out. Those callers are
+`path_lookupat()`, `path_parentat()`, `path_mountpoint()` and
+`path_openat()` each of which handles the differing requirements of
+different system calls.
+
+`path_parentat()` is clearly the simplest - it just wraps a little bit
+of housekeeping around `link_path_walk()` and returns the parent
+directory and final component to the caller.  The caller will be either
+aiming to create a name (via `filename_create()`) or remove or rename
+a name (in which case `user_path_parent()` is used).  They will use
+`i_mutex` to exclude other changes while they validate and then
+perform their operation.
+
+`path_lookupat()` is nearly as simple - it is used when an existing
+object is wanted such as by `stat()` or `chmod()`.  It essentially just
+calls `walk_component()` on the final component through a call to
+`lookup_last()`.  `path_lookupat()` returns just the final dentry.
+
+`path_mountpoint()` handles the special case of unmounting which must
+not try to revalidate the mounted filesystem.  It effectively
+contains, through a call to `mountpoint_last()`, an alternate
+implementation of `lookup_slow()` which skips that step.  This is
+important when unmounting a filesystem that is inaccessible, such as
+one provided by a dead NFS server.
+
+Finally `path_openat()` is used for the `open()` system call; it
+contains, in support functions starting with "`do_last()`", all the
+complexity needed to handle the different subtleties of O_CREAT (with
+or without O_EXCL), final "`/`" characters, and trailing symbolic
+links.  We will revisit this in the final part of this series, which
+focuses on those symbolic links.  "`do_last()`" will sometimes, but
+not always, take `i_mutex`, depending on what it finds.
+
+Each of these, or the functions which call them, need to be alert to
+the possibility that the final component is not `LAST_NORM`.  If the
+goal of the lookup is to create something, then any value for
+`last_type` other than `LAST_NORM` will result in an error.  For
+example if `path_parentat()` reports `LAST_DOTDOT`, then the caller
+won't try to create that name.  They also check for trailing slashes
+by testing `last.name[last.len]`.  If there is any character beyond
+the final component, it must be a trailing slash.
+
+Revalidation and automounts
+---------------------------
+
+Apart from symbolic links, there are only two parts of the "REF-walk"
+process not yet covered.  One is the handling of stale cache entries
+and the other is automounts.
+
+On filesystems that require it, the lookup routines will call the
+`->d_revalidate()` dentry method to ensure that the cached information
+is current.  This will often confirm validity or update a few details
+from a server.  In some cases it may find that there has been change
+further up the path and that something that was thought to be valid
+previously isn't really.  When this happens the lookup of the whole
+path is aborted and retried with the "`LOOKUP_REVAL`" flag set.  This
+forces revalidation to be more thorough.  We will see more details of
+this retry process in the next article.
+
+Automount points are locations in the filesystem where an attempt to
+lookup a name can trigger changes to how that lookup should be
+handled, in particular by mounting a filesystem there.  These are
+covered in greater detail in autofs4.txt in the Linux documentation
+tree, but a few notes specifically related to path lookup are in order
+here.
+
+The Linux VFS has a concept of "managed" dentries which is reflected
+in function names such as "`follow_managed()`".  There are three
+potentially interesting things about these dentries corresponding
+to three different flags that might be set in `dentry->d_flags`:
+
+### `DCACHE_MANAGE_TRANSIT` ###
+
+If this flag has been set, then the filesystem has requested that the
+`d_manage()` dentry operation be called before handling any possible
+mount point.  This can perform two particular services:
+
+It can block to avoid races.  If an automount point is being
+unmounted, the `d_manage()` function will usually wait for that
+process to complete before letting the new lookup proceed and possibly
+trigger a new automount.
+
+It can selectively allow only some processes to transit through a
+mount point.  When a server process is managing automounts, it may
+need to access a directory without triggering normal automount
+processing.  That server process can identify itself to the `autofs`
+filesystem, which will then give it a special pass through
+`d_manage()` by returning `-EISDIR`.
+
+### `DCACHE_MOUNTED` ###
+
+This flag is set on every dentry that is mounted on.  As Linux
+supports multiple filesystem namespaces, it is possible that the
+dentry may not be mounted on in *this* namespace, just in some
+other.  So this flag is seen as a hint, not a promise.
+
+If this flag is set, and `d_manage()` didn't return `-EISDIR`,
+`lookup_mnt()` is called to examine the mount hash table (honoring the
+`mount_lock` described earlier) and possibly return a new `vfsmount`
+and a new `dentry` (both with counted references).
+
+### `DCACHE_NEED_AUTOMOUNT` ###
+
+If `d_manage()` allowed us to get this far, and `lookup_mnt()` didn't
+find a mount point, then this flag causes the `d_automount()` dentry
+operation to be called.
+
+The `d_automount()` operation can be arbitrarily complex and may
+communicate with server processes etc. but it should ultimately either
+report that there was an error, that there was nothing to mount, or
+should provide an updated `struct path` with new `dentry` and `vfsmount`.
+
+In the latter case, `finish_automount()` will be called to safely
+install the new mount point into the mount table.
+
+There is no new locking of import here and it is important that no
+locks (only counted references) are held over this processing due to
+the very real possibility of extended delays.
+This will become more important next time when we examine RCU-walk
+which is particularly sensitive to delays.
+
+RCU-walk - faster pathname lookup in Linux
+==========================================
+
+RCU-walk is another algorithm for performing pathname lookup in Linux.
+It is in many ways similar to REF-walk and the two share quite a bit
+of code.  The significant difference in RCU-walk is how it allows for
+the possibility of concurrent access.
+
+We noted that REF-walk is complex because there are numerous details
+and special cases.  RCU-walk reduces this complexity by simply
+refusing to handle a number of cases -- it instead falls back to
+REF-walk.  The difficulty with RCU-walk comes from a different
+direction: unfamiliarity.  The locking rules when depending on RCU are
+quite different from traditional locking, so we will spend a little extra
+time when we come to those.
+
+Clear demarcation of roles
+--------------------------
+
+The easiest way to manage concurrency is to forcibly stop any other
+thread from changing the data structures that a given thread is
+looking at.  In cases where no other thread would even think of
+changing the data and lots of different threads want to read at the
+same time, this can be very costly.  Even when using locks that permit
+multiple concurrent readers, the simple act of updating the count of
+the number of current readers can impose an unwanted cost.  So the
+goal when reading a shared data structure that no other process is
+changing is to avoid writing anything to memory at all.  Take no
+locks, increment no counts, leave no footprints.
+
+The REF-walk mechanism already described certainly doesn't follow this
+principle, but then it is really designed to work when there may well
+be other threads modifying the data.  RCU-walk, in contrast, is
+designed for the common situation where there are lots of frequent
+readers and only occasional writers.  This may not be common in all
+parts of the filesystem tree, but in many parts it will be.  For the
+other parts it is important that RCU-walk can quickly fall back to
+using REF-walk.
+
+Pathname lookup always starts in RCU-walk mode but only remains there
+as long as what it is looking for is in the cache and is stable.  It
+dances lightly down the cached filesystem image, leaving no footprints
+and carefully watching where it is, to be sure it doesn't trip.  If it
+notices that something has changed or is changing, or if something
+isn't in the cache, then it tries to stop gracefully and switch to
+REF-walk.
+
+This stopping requires getting a counted reference on the current
+`vfsmount` and `dentry`, and ensuring that these are still valid -
+that a path walk with REF-walk would have found the same entries.
+This is an invariant that RCU-walk must guarantee.  It can only make
+decisions, such as selecting the next step, that are decisions which
+REF-walk could also have made if it were walking down the tree at the
+same time.  If the graceful stop succeeds, the rest of the path is
+processed with the reliable, if slightly sluggish, REF-walk.  If
+RCU-walk finds it cannot stop gracefully, it simply gives up and
+restarts from the top with REF-walk.
+
+This pattern of "try RCU-walk, if that fails try REF-walk" can be
+clearly seen in functions like `filename_lookup()`,
+`filename_parentat()`, `filename_mountpoint()`,
+`do_filp_open()`, and `do_file_open_root()`.  These five
+correspond roughly to the four `path_`* functions we met earlier,
+each of which calls `link_path_walk()`.  The `path_*` functions are
+called using different mode flags until a mode is found which works.
+They are first called with `LOOKUP_RCU` set to request "RCU-walk".  If
+that fails with the error `ECHILD` they are called again with no
+special flag to request "REF-walk".  If either of those report the
+error `ESTALE` a final attempt is made with `LOOKUP_REVAL` set (and no
+`LOOKUP_RCU`) to ensure that entries found in the cache are forcibly
+revalidated - normally entries are only revalidated if the filesystem
+determines that they are too old to trust.
+
+The `LOOKUP_RCU` attempt may drop that flag internally and switch to
+REF-walk, but will never then try to switch back to RCU-walk.  Places
+that trip up RCU-walk are much more likely to be near the leaves and
+so it is very unlikely that there will be much, if any, benefit from
+switching back.
+
+RCU and seqlocks: fast and light
+--------------------------------
+
+RCU is, unsurprisingly, critical to RCU-walk mode.  The
+`rcu_read_lock()` is held for the entire time that RCU-walk is walking
+down a path.  The particular guarantee it provides is that the key
+data structures - dentries, inodes, super_blocks, and mounts - will
+not be freed while the lock is held.  They might be unlinked or
+invalidated in one way or another, but the memory will not be
+repurposed so values in various fields will still be meaningful.  This
+is the only guarantee that RCU provides; everything else is done using
+seqlocks.
+
+As we saw above, REF-walk holds a counted reference to the current
+dentry and the current vfsmount, and does not release those references
+before taking references to the "next" dentry or vfsmount.  It also
+sometimes takes the `d_lock` spinlock.  These references and locks are
+taken to prevent certain changes from happening.  RCU-walk must not
+take those references or locks and so cannot prevent such changes.
+Instead, it checks to see if a change has been made, and aborts or
+retries if it has.
+
+To preserve the invariant mentioned above (that RCU-walk may only make
+decisions that REF-walk could have made), it must make the checks at
+or near the same places that REF-walk holds the references.  So, when
+REF-walk increments a reference count or takes a spinlock, RCU-walk
+samples the status of a seqlock using `read_seqcount_begin()` or a
+similar function.  When REF-walk decrements the count or drops the
+lock, RCU-walk checks if the sampled status is still valid using
+`read_seqcount_retry()` or similar.
+
+However, there is a little bit more to seqlocks than that.  If
+RCU-walk accesses two different fields in a seqlock-protected
+structure, or accesses the same field twice, there is no a priori
+guarantee of any consistency between those accesses.  When consistency
+is needed - which it usually is - RCU-walk must take a copy and then
+use `read_seqcount_retry()` to validate that copy.
+
+`read_seqcount_retry()` not only checks the sequence number, but also
+imposes a memory barrier so that no memory-read instruction from
+*before* the call can be delayed until *after* the call, either by the
+CPU or by the compiler.  A simple example of this can be seen in
+`slow_dentry_cmp()` which, for filesystems which do not use simple
+byte-wise name equality, calls into the filesystem to compare a name
+against a dentry.  The length and name pointer are copied into local
+variables, then `read_seqcount_retry()` is called to confirm the two
+are consistent, and only then is `->d_compare()` called.  When
+standard filename comparison is used, `dentry_cmp()` is called
+instead.  Notably it does _not_ use `read_seqcount_retry()`, but
+instead has a large comment explaining why the consistency guarantee
+isn't necessary.  A subsequent `read_seqcount_retry()` will be
+sufficient to catch any problem that could occur at this point.
+
+With that little refresher on seqlocks out of the way we can look at
+the bigger picture of how RCU-walk uses seqlocks.
+
+### `mount_lock` and `nd->m_seq` ###
+
+We already met the `mount_lock` seqlock when REF-walk used it to
+ensure that crossing a mount point is performed safely.  RCU-walk uses
+it for that too, but for quite a bit more.
+
+Instead of taking a counted reference to each `vfsmount` as it
+descends the tree, RCU-walk samples the state of `mount_lock` at the
+start of the walk and stores this initial sequence number in the
+`struct nameidata` in the `m_seq` field.  This one lock and one
+sequence number are used to validate all accesses to all `vfsmounts`,
+and all mount point crossings.  As changes to the mount table are
+relatively rare, it is reasonable to fall back on REF-walk any time
+that any "mount" or "unmount" happens.
+
+`m_seq` is checked (using `read_seqretry()`) at the end of an RCU-walk
+sequence, whether switching to REF-walk for the rest of the path or
+when the end of the path is reached.  It is also checked when stepping
+down over a mount point (in `__follow_mount_rcu()`) or up (in
+`follow_dotdot_rcu()`).  If it is ever found to have changed, the
+whole RCU-walk sequence is aborted and the path is processed again by
+REF-walk.
+
+If RCU-walk finds that `mount_lock` hasn't changed then it can be sure
+that, had REF-walk taken counted references on each vfsmount, the
+results would have been the same.  This ensures the invariant holds,
+at least for vfsmount structures.
+
+### `dentry->d_seq` and `nd->seq`. ###
+
+In place of taking a count or lock on `d_reflock`, RCU-walk samples
+the per-dentry `d_seq` seqlock, and stores the sequence number in the
+`seq` field of the nameidata structure, so `nd->seq` should always be
+the current sequence number of `nd->dentry`.  This number needs to be
+revalidated after copying, and before using, the name, parent, or
+inode of the dentry.
+
+The handling of the name we have already looked at, and the parent is
+only accessed in `follow_dotdot_rcu()` which fairly trivially follows
+the required pattern, though it does so for three different cases.
+
+When not at a mount point, `d_parent` is followed and its `d_seq` is
+collected.  When we are at a mount point, we instead follow the
+`mnt->mnt_mountpoint` link to get a new dentry and collect its
+`d_seq`.  Then, after finally finding a `d_parent` to follow, we must
+check if we have landed on a mount point and, if so, must find that
+mount point and follow the `mnt->mnt_root` link.  This would imply a
+somewhat unusual, but certainly possible, circumstance where the
+starting point of the path lookup was in part of the filesystem that
+was mounted on, and so not visible from the root.
+
+The inode pointer, stored in `->d_inode`, is a little more
+interesting.  The inode will always need to be accessed at least
+twice, once to determine if it is NULL and once to verify access
+permissions.  Symlink handling requires a validated inode pointer too.
+Rather than revalidating on each access, a copy is made on the first
+access and it is stored in the `inode` field of `nameidata` from where
+it can be safely accessed without further validation.
+
+`lookup_fast()` is the only lookup routine that is used in RCU-mode,
+`lookup_slow()` being too slow and requiring locks.  It is in
+`lookup_fast()` that we find the important "hand over hand" tracking
+of the current dentry.
+
+The current `dentry` and current `seq` number are passed to
+`__d_lookup_rcu()` which, on success, returns a new `dentry` and a
+new `seq` number.  `lookup_fast()` then copies the inode pointer and
+revalidates the new `seq` number.  It then validates the old `dentry`
+with the old `seq` number one last time and only then continues.  This
+process of getting the `seq` number of the new dentry and then
+checking the `seq` number of the old exactly mirrors the process of
+getting a counted reference to the new dentry before dropping that for
+the old dentry which we saw in REF-walk.
+
+### No `inode->i_mutex` or even `rename_lock` ###
+
+A mutex is a fairly heavyweight lock that can only be taken when it is
+permissible to sleep.  As `rcu_read_lock()` forbids sleeping,
+`inode->i_mutex` plays no role in RCU-walk.  If some other thread does
+take `i_mutex` and modifies the directory in a way that RCU-walk needs
+to notice, the result will be either that RCU-walk fails to find the
+dentry that it is looking for, or it will find a dentry which
+`read_seqretry()` won't validate.  In either case it will drop down to
+REF-walk mode which can take whatever locks are needed.
+
+Though `rename_lock` could be used by RCU-walk as it doesn't require
+any sleeping, RCU-walk doesn't bother.  REF-walk uses `rename_lock` to
+protect against the possibility of hash chains in the dcache changing
+while they are being searched.  This can result in failing to find
+something that actually is there.  When RCU-walk fails to find
+something in the dentry cache, whether it is really there or not, it
+already drops down to REF-walk and tries again with appropriate
+locking.  This neatly handles all cases, so adding extra checks on
+rename_lock would bring no significant value.
+
+`unlazy walk()` and `complete_walk()`
+-------------------------------------
+
+That "dropping down to REF-walk" typically involves a call to
+`unlazy_walk()`, so named because "RCU-walk" is also sometimes
+referred to as "lazy walk".  `unlazy_walk()` is called when
+following the path down to the current vfsmount/dentry pair seems to
+have proceeded successfully, but the next step is problematic.  This
+can happen if the next name cannot be found in the dcache, if
+permission checking or name revalidation couldn't be achieved while
+the `rcu_read_lock()` is held (which forbids sleeping), if an
+automount point is found, or in a couple of cases involving symlinks.
+It is also called from `complete_walk()` when the lookup has reached
+the final component, or the very end of the path, depending on which
+particular flavor of lookup is used.
+
+Other reasons for dropping out of RCU-walk that do not trigger a call
+to `unlazy_walk()` are when some inconsistency is found that cannot be
+handled immediately, such as `mount_lock` or one of the `d_seq`
+seqlocks reporting a change.  In these cases the relevant function
+will return `-ECHILD` which will percolate up until it triggers a new
+attempt from the top using REF-walk.
+
+For those cases where `unlazy_walk()` is an option, it essentially
+takes a reference on each of the pointers that it holds (vfsmount,
+dentry, and possibly some symbolic links) and then verifies that the
+relevant seqlocks have not been changed.  If there have been changes,
+it, too, aborts with `-ECHILD`, otherwise the transition to REF-walk
+has been a success and the lookup process continues.
+
+Taking a reference on those pointers is not quite as simple as just
+incrementing a counter.  That works to take a second reference if you
+already have one (often indirectly through another object), but it
+isn't sufficient if you don't actually have a counted reference at
+all.  For `dentry->d_lockref`, it is safe to increment the reference
+counter to get a reference unless it has been explicitly marked as
+"dead" which involves setting the counter to `-128`.
+`lockref_get_not_dead()` achieves this.
+
+For `mnt->mnt_count` it is safe to take a reference as long as
+`mount_lock` is then used to validate the reference.  If that
+validation fails, it may *not* be safe to just drop that reference in
+the standard way of calling `mnt_put()` - an unmount may have
+progressed too far.  So the code in `legitimize_mnt()`, when it
+finds that the reference it got might not be safe, checks the
+`MNT_SYNC_UMOUNT` flag to determine if a simple `mnt_put()` is
+correct, or if it should just decrement the count and pretend none of
+this ever happened.
+
+Taking care in filesystems
+---------------------------
+
+RCU-walk depends almost entirely on cached information and often will
+not call into the filesystem at all.  However there are two places,
+besides the already-mentioned component-name comparison, where the
+file system might be included in RCU-walk, and it must know to be
+careful.
+
+If the filesystem has non-standard permission-checking requirements -
+such as a networked filesystem which may need to check with the server
+- the `i_op->permission` interface might be called during RCU-walk.
+In this case an extra "`MAY_NOT_BLOCK`" flag is passed so that it
+knows not to sleep, but to return `-ECHILD` if it cannot complete
+promptly.  `i_op->permission` is given the inode pointer, not the
+dentry, so it doesn't need to worry about further consistency checks.
+However if it accesses any other filesystem data structures, it must
+ensure they are safe to be accessed with only the `rcu_read_lock()`
+held.  This typically means they must be freed using `kfree_rcu()` or
+similar.
+
+[`READ_ONCE()`]: https://lwn.net/Articles/624126/
+
+If the filesystem may need to revalidate dcache entries, then
+`d_op->d_revalidate` may be called in RCU-walk too.  This interface
+*is* passed the dentry but does not have access to the `inode` or the
+`seq` number from the `nameidata`, so it needs to be extra careful
+when accessing fields in the dentry.  This "extra care" typically
+involves using `ACCESS_ONCE()` or the newer [`READ_ONCE()`] to access
+fields, and verifying the result is not NULL before using it.  This
+pattern can be see in `nfs_lookup_revalidate()`.
+
+A pair of patterns
+------------------
+
+In various places in the details of REF-walk and RCU-walk, and also in
+the big picture, there are a couple of related patterns that are worth
+being aware of.
+
+The first is "try quickly and check, if that fails try slowly".  We
+can see that in the high-level approach of first trying RCU-walk and
+then trying REF-walk, and in places where `unlazy_walk()` is used to
+switch to REF-walk for the rest of the path.  We also saw it earlier
+in `dget_parent()` when following a "`..`" link.  It tries a quick way
+to get a reference, then falls back to taking locks if needed.
+
+The second pattern is "try quickly and check, if that fails try
+again - repeatedly".  This is seen with the use of `rename_lock` and
+`mount_lock` in REF-walk.  RCU-walk doesn't make use of this pattern -
+if anything goes wrong it is much safer to just abort and try a more
+sedate approach.
+
+The emphasis here is "try quickly and check".  It should probably be
+"try quickly _and carefully,_ then check".  The fact that checking is
+needed is a reminder that the system is dynamic and only a limited
+number of things are safe at all.  The most likely cause of errors in
+this whole process is assuming something is safe when in reality it
+isn't.  Careful consideration of what exactly guarantees the safety of
+each access is sometimes necessary.
+
+A walk among the symlinks
+=========================
+
+There are several basic issues that we will examine to understand the
+handling of symbolic links:  the symlink stack, together with cache
+lifetimes, will help us understand the overall recursive handling of
+symlinks and lead to the special care needed for the final component.
+Then a consideration of access-time updates and summary of the various
+flags controlling lookup will finish the story.
+
+The symlink stack
+-----------------
+
+There are only two sorts of filesystem objects that can usefully
+appear in a path prior to the final component: directories and symlinks.
+Handling directories is quite straightforward: the new directory
+simply becomes the starting point at which to interpret the next
+component on the path.  Handling symbolic links requires a bit more
+work.
+
+Conceptually, symbolic links could be handled by editing the path.  If
+a component name refers to a symbolic link, then that component is
+replaced by the body of the link and, if that body starts with a '/',
+then all preceding parts of the path are discarded.  This is what the
+"`readlink -f`" command does, though it also edits out "`.`" and
+"`..`" components.
+
+Directly editing the path string is not really necessary when looking
+up a path, and discarding early components is pointless as they aren't
+looked at anyway.  Keeping track of all remaining components is
+important, but they can of course be kept separately; there is no need
+to concatenate them.  As one symlink may easily refer to another,
+which in turn can refer to a third, we may need to keep the remaining
+components of several paths, each to be processed when the preceding
+ones are completed.  These path remnants are kept on a stack of
+limited size.
+
+There are two reasons for placing limits on how many symlinks can
+occur in a single path lookup.  The most obvious is to avoid loops.
+If a symlink referred to itself either directly or through
+intermediaries, then following the symlink can never complete
+successfully - the error `ELOOP` must be returned.  Loops can be
+detected without imposing limits, but limits are the simplest solution
+and, given the second reason for restriction, quite sufficient.
+
+[outlined recently]: http://thread.gmane.org/gmane.linux.kernel/1934390/focus=1934550
+
+The second reason was [outlined recently] by Linus:
+
+>  Because it's a latency and DoS issue too. We need to react well to
+>  true loops, but also to "very deep" non-loops. It's not about memory
+>  use, it's about users triggering unreasonable CPU resources.
+
+Linux imposes a limit on the length of any pathname: `PATH_MAX`, which
+is 4096.  There are a number of reasons for this limit; not letting the
+kernel spend too much time on just one path is one of them.  With
+symbolic links you can effectively generate much longer paths so some
+sort of limit is needed for the same reason.  Linux imposes a limit of
+at most 40 symlinks in any one path lookup.  It previously imposed a
+further limit of eight on the maximum depth of recursion, but that was
+raised to 40 when a separate stack was implemented, so there is now
+just the one limit.
+
+The `nameidata` structure that we met in an earlier article contains a
+small stack that can be used to store the remaining part of up to two
+symlinks.  In many cases this will be sufficient.  If it isn't, a
+separate stack is allocated with room for 40 symlinks.  Pathname
+lookup will never exceed that stack as, once the 40th symlink is
+detected, an error is returned.
+
+It might seem that the name remnants are all that needs to be stored on
+this stack, but we need a bit more.  To see that, we need to move on to
+cache lifetimes.
+
+Storage and lifetime of cached symlinks
+---------------------------------------
+
+Like other filesystem resources, such as inodes and directory
+entries, symlinks are cached by Linux to avoid repeated costly access
+to external storage.  It is particularly important for RCU-walk to be
+able to find and temporarily hold onto these cached entries, so that
+it doesn't need to drop down into REF-walk.
+
+[object-oriented design pattern]: https://lwn.net/Articles/446317/
+
+While each filesystem is free to make its own choice, symlinks are
+typically stored in one of two places.  Short symlinks are often
+stored directly in the inode.  When a filesystem allocates a `struct
+inode` it typically allocates extra space to store private data (a
+common [object-oriented design pattern] in the kernel).  This will
+sometimes include space for a symlink.  The other common location is
+in the page cache, which normally stores the content of files.  The
+pathname in a symlink can be seen as the content of that symlink and
+can easily be stored in the page cache just like file content.
+
+When neither of these is suitable, the next most likely scenario is
+that the filesystem will allocate some temporary memory and copy or
+construct the symlink content into that memory whenever it is needed.
+
+When the symlink is stored in the inode, it has the same lifetime as
+the inode which, itself, is protected by RCU or by a counted reference
+on the dentry.  This means that the mechanisms that pathname lookup
+uses to access the dcache and icache (inode cache) safely are quite
+sufficient for accessing some cached symlinks safely.  In these cases,
+the `i_link` pointer in the inode is set to point to wherever the
+symlink is stored and it can be accessed directly whenever needed.
+
+When the symlink is stored in the page cache or elsewhere, the
+situation is not so straightforward.  A reference on a dentry or even
+on an inode does not imply any reference on cached pages of that
+inode, and even an `rcu_read_lock()` is not sufficient to ensure that
+a page will not disappear.  So for these symlinks the pathname lookup
+code needs to ask the filesystem to provide a stable reference and,
+significantly, needs to release that reference when it is finished
+with it.
+
+Taking a reference to a cache page is often possible even in RCU-walk
+mode.  It does require making changes to memory, which is best avoided,
+but that isn't necessarily a big cost and it is better than dropping
+out of RCU-walk mode completely.  Even filesystems that allocate
+space to copy the symlink into can use `GFP_ATOMIC` to often successfully
+allocate memory without the need to drop out of RCU-walk.  If a
+filesystem cannot successfully get a reference in RCU-walk mode, it
+must return `-ECHILD` and `unlazy_walk()` will be called to return to
+REF-walk mode in which the filesystem is allowed to sleep.
+
+The place for all this to happen is the `i_op->follow_link()` inode
+method.  In the present mainline code this is never actually called in
+RCU-walk mode as the rewrite is not quite complete.  It is likely that
+in a future release this method will be passed an `inode` pointer when
+called in RCU-walk mode so it both (1) knows to be careful, and (2) has the
+validated pointer.  Much like the `i_op->permission()` method we
+looked at previously, `->follow_link()` would need to be careful that
+all the data structures it references are safe to be accessed while
+holding no counted reference, only the RCU lock.  Though getting a
+reference with `->follow_link()` is not yet done in RCU-walk mode, the
+code is ready to release the reference when that does happen.
+
+This need to drop the reference to a symlink adds significant
+complexity.  It requires a reference to the inode so that the
+`i_op->put_link()` inode operation can be called.  In REF-walk, that
+reference is kept implicitly through a reference to the dentry, so
+keeping the `struct path` of the symlink is easiest.  For RCU-walk,
+the pointer to the inode is kept separately.  To allow switching from
+RCU-walk back to REF-walk in the middle of processing nested symlinks
+we also need the seq number for the dentry so we can confirm that
+switching back was safe.
+
+Finally, when providing a reference to a symlink, the filesystem also
+provides an opaque "cookie" that must be passed to `->put_link()` so that it
+knows what to free.  This might be the allocated memory area, or a
+pointer to the `struct page` in the page cache, or something else
+completely.  Only the filesystem knows what it is.
+
+In order for the reference to each symlink to be dropped when the walk completes,
+whether in RCU-walk or REF-walk, the symlink stack needs to contain,
+along with the path remnants:
+
+- the `struct path` to provide a reference to the inode in REF-walk
+- the `struct inode *` to provide a reference to the inode in RCU-walk
+- the `seq` to allow the path to be safely switched from RCU-walk to REF-walk
+- the `cookie` that tells `->put_path()` what to put.
+
+This means that each entry in the symlink stack needs to hold five
+pointers and an integer instead of just one pointer (the path
+remnant).  On a 64-bit system, this is about 40 bytes per entry;
+with 40 entries it adds up to 1600 bytes total, which is less than
+half a page.  So it might seem like a lot, but is by no means
+excessive.
+
+Note that, in a given stack frame, the path remnant (`name`) is not
+part of the symlink that the other fields refer to.  It is the remnant
+to be followed once that symlink has been fully parsed.
+
+Following the symlink
+---------------------
+
+The main loop in `link_path_walk()` iterates seamlessly over all
+components in the path and all of the non-final symlinks.  As symlinks
+are processed, the `name` pointer is adjusted to point to a new
+symlink, or is restored from the stack, so that much of the loop
+doesn't need to notice.  Getting this `name` variable on and off the
+stack is very straightforward; pushing and popping the references is
+a little more complex.
+
+When a symlink is found, `walk_component()` returns the value `1`
+(`0` is returned for any other sort of success, and a negative number
+is, as usual, an error indicator).  This causes `get_link()` to be
+called; it then gets the link from the filesystem.  Providing that
+operation is successful, the old path `name` is placed on the stack,
+and the new value is used as the `name` for a while.  When the end of
+the path is found (i.e. `*name` is `'\0'`) the old `name` is restored
+off the stack and path walking continues.
+
+Pushing and popping the reference pointers (inode, cookie, etc.) is more
+complex in part because of the desire to handle tail recursion.  When
+the last component of a symlink itself points to a symlink, we
+want to pop the symlink-just-completed off the stack before pushing
+the symlink-just-found to avoid leaving empty path remnants that would
+just get in the way.
+
+It is most convenient to push the new symlink references onto the
+stack in `walk_component()` immediately when the symlink is found;
+`walk_component()` is also the last piece of code that needs to look at the
+old symlink as it walks that last component.  So it is quite
+convenient for `walk_component()` to release the old symlink and pop
+the references just before pushing the reference information for the
+new symlink.  It is guided in this by two flags; `WALK_GET`, which
+gives it permission to follow a symlink if it finds one, and
+`WALK_PUT`, which tells it to release the current symlink after it has been
+followed.  `WALK_PUT` is tested first, leading to a call to
+`put_link()`.  `WALK_GET` is tested subsequently (by
+`should_follow_link()`) leading to a call to `pick_link()` which sets
+up the stack frame.
+
+### Symlinks with no final component ###
+
+A pair of special-case symlinks deserve a little further explanation.
+Both result in a new `struct path` (with mount and dentry) being set
+up in the `nameidata`, and result in `get_link()` returning `NULL`.
+
+The more obvious case is a symlink to "`/`".  All symlinks starting
+with "`/`" are detected in `get_link()` which resets the `nameidata`
+to point to the effective filesystem root.  If the symlink only
+contains "`/`" then there is nothing more to do, no components at all,
+so `NULL` is returned to indicate that the symlink can be released and
+the stack frame discarded.
+
+The other case involves things in `/proc` that look like symlinks but
+aren't really.
+
+>     $ ls -l /proc/self/fd/1
+>     lrwx------ 1 neilb neilb 64 Jun 13 10:19 /proc/self/fd/1 -> /dev/pts/4
+
+Every open file descriptor in any process is represented in `/proc` by
+something that looks like a symlink.  It is really a reference to the
+target file, not just the name of it.  When you `readlink` these
+objects you get a name that might refer to the same file - unless it
+has been unlinked or mounted over.  When `walk_component()` follows
+one of these, the `->follow_link()` method in "procfs" doesn't return
+a string name, but instead calls `nd_jump_link()` which updates the
+`nameidata` in place to point to that target.  `->follow_link()` then
+returns `NULL`.  Again there is no final component and `get_link()`
+reports this by leaving the `last_type` field of `nameidata` as
+`LAST_BIND`.
+
+Following the symlink in the final component
+--------------------------------------------
+
+All this leads to `link_path_walk()` walking down every component, and
+following all symbolic links it finds, until it reaches the final
+component.  This is just returned in the `last` field of `nameidata`.
+For some callers, this is all they need; they want to create that
+`last` name if it doesn't exist or give an error if it does.  Other
+callers will want to follow a symlink if one is found, and possibly
+apply special handling to the last component of that symlink, rather
+than just the last component of the original file name.  These callers
+potentially need to call `link_path_walk()` again and again on
+successive symlinks until one is found that doesn't point to another
+symlink.
+
+This case is handled by the relevant caller of `link_path_walk()`, such as
+`path_lookupat()` using a loop that calls `link_path_walk()`, and then
+handles the final component.  If the final component is a symlink
+that needs to be followed, then `trailing_symlink()` is called to set
+things up properly and the loop repeats, calling `link_path_walk()`
+again.  This could loop as many as 40 times if the last component of
+each symlink is another symlink.
+
+The various functions that examine the final component and possibly
+report that it is a symlink are `lookup_last()`, `mountpoint_last()`
+and `do_last()`, each of which use the same convention as
+`walk_component()` of returning `1` if a symlink was found that needs
+to be followed.
+
+Of these, `do_last()` is the most interesting as it is used for
+opening a file.  Part of `do_last()` runs with `i_mutex` held and this
+part is in a separate function: `lookup_open()`.
+
+Explaining `do_last()` completely is beyond the scope of this article,
+but a few highlights should help those interested in exploring the
+code.
+
+1. Rather than just finding the target file, `do_last()` needs to open
+ it.  If the file was found in the dcache, then `vfs_open()` is used for
+ this.  If not, then `lookup_open()` will either call `atomic_open()` (if
+ the filesystem provides it) to combine the final lookup with the open, or
+ will perform the separate `lookup_real()` and `vfs_create()` steps
+ directly.  In the later case the actual "open" of this newly found or
+ created file will be performed by `vfs_open()`, just as if the name
+ were found in the dcache.
+
+2. `vfs_open()` can fail with `-EOPENSTALE` if the cached information
+ wasn't quite current enough.  Rather than restarting the lookup from
+ the top with `LOOKUP_REVAL` set, `lookup_open()` is called instead,
+ giving the filesystem a chance to resolve small inconsistencies.
+ If that doesn't work, only then is the lookup restarted from the top.
+
+3. An open with O_CREAT **does** follow a symlink in the final component,
+     unlike other creation system calls (like `mkdir`).  So the sequence:
+
+     >     ln -s bar /tmp/foo
+     >     echo hello > /tmp/foo
+
+     will create a file called `/tmp/bar`.  This is not permitted if
+     `O_EXCL` is set but otherwise is handled for an O_CREAT open much
+     like for a non-creating open: `should_follow_link()` returns `1`, and
+     so does `do_last()` so that `trailing_symlink()` gets called and the
+     open process continues on the symlink that was found.
+
+Updating the access time
+------------------------
+
+We previously said of RCU-walk that it would "take no locks, increment
+no counts, leave no footprints."  We have since seen that some
+"footprints" can be needed when handling symlinks as a counted
+reference (or even a memory allocation) may be needed.  But these
+footprints are best kept to a minimum.
+
+One other place where walking down a symlink can involve leaving
+footprints in a way that doesn't affect directories is in updating access times.
+In Unix (and Linux) every filesystem object has a "last accessed
+time", or "`atime`".  Passing through a directory to access a file
+within is not considered to be an access for the purposes of
+`atime`; only listing the contents of a directory can update its `atime`.
+Symlinks are different it seems.  Both reading a symlink (with `readlink()`)
+and looking up a symlink on the way to some other destination can
+update the atime on that symlink.
+
+[clearest statement]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_08
+
+It is not clear why this is the case; POSIX has little to say on the
+subject.  The [clearest statement] is that, if a particular implementation
+updates a timestamp in a place not specified by POSIX, this must be
+documented "except that any changes caused by pathname resolution need
+not be documented".  This seems to imply that POSIX doesn't really
+care about access-time updates during pathname lookup.
+
+[Linux 1.3.87]: https://git.kernel.org/cgit/linux/kernel/git/history/history.git/diff/fs/ext2/symlink.c?id=f806c6db77b8eaa6e00dcfb6b567706feae8dbb8
+
+An examination of history shows that prior to [Linux 1.3.87], the ext2
+filesystem, at least, didn't update atime when following a link.
+Unfortunately we have no record of why that behavior was changed.
+
+In any case, access time must now be updated and that operation can be
+quite complex.  Trying to stay in RCU-walk while doing it is best
+avoided.  Fortunately it is often permitted to skip the `atime`
+update.  Because `atime` updates cause performance problems in various
+areas, Linux supports the `relatime` mount option, which generally
+limits the updates of `atime` to once per day on files that aren't
+being changed (and symlinks never change once created).  Even without
+`relatime`, many filesystems record `atime` with a one-second
+granularity, so only one update per second is required.
+
+It is easy to test if an `atime` update is needed while in RCU-walk
+mode and, if it isn't, the update can be skipped and RCU-walk mode
+continues.  Only when an `atime` update is actually required does the
+path walk drop down to REF-walk.  All of this is handled in the
+`get_link()` function.
+
+A few flags
+-----------
+
+A suitable way to wrap up this tour of pathname walking is to list
+the various flags that can be stored in the `nameidata` to guide the
+lookup process.  Many of these are only meaningful on the final
+component, others reflect the current state of the pathname lookup.
+And then there is `LOOKUP_EMPTY`, which doesn't fit conceptually with
+the others.  If this is not set, an empty pathname causes an error
+very early on.  If it is set, empty pathnames are not considered to be
+an error.
+
+### Global state flags ###
+
+We have already met two global state flags: `LOOKUP_RCU` and
+`LOOKUP_REVAL`.  These select between one of three overall approaches
+to lookup: RCU-walk, REF-walk, and REF-walk with forced revalidation.
+
+`LOOKUP_PARENT` indicates that the final component hasn't been reached
+yet.  This is primarily used to tell the audit subsystem the full
+context of a particular access being audited.
+
+`LOOKUP_ROOT` indicates that the `root` field in the `nameidata` was
+provided by the caller, so it shouldn't be released when it is no
+longer needed.
+
+`LOOKUP_JUMPED` means that the current dentry was chosen not because
+it had the right name but for some other reason.  This happens when
+following "`..`", following a symlink to `/`, crossing a mount point
+or accessing a "`/proc/$PID/fd/$FD`" symlink.  In this case the
+filesystem has not been asked to revalidate the name (with
+`d_revalidate()`).  In such cases the inode may still need to be
+revalidated, so `d_op->d_weak_revalidate()` is called if
+`LOOKUP_JUMPED` is set when the look completes - which may be at the
+final component or, when creating, unlinking, or renaming, at the penultimate component.
+
+### Final-component flags ###
+
+Some of these flags are only set when the final component is being
+considered.  Others are only checked for when considering that final
+component.
+
+`LOOKUP_AUTOMOUNT` ensures that, if the final component is an automount
+point, then the mount is triggered.  Some operations would trigger it
+anyway, but operations like `stat()` deliberately don't.  `statfs()`
+needs to trigger the mount but otherwise behaves a lot like `stat()`, so
+it sets `LOOKUP_AUTOMOUNT`, as does "`quotactl()`" and the handling of
+"`mount --bind`".
+
+`LOOKUP_FOLLOW` has a similar function to `LOOKUP_AUTOMOUNT` but for
+symlinks.  Some system calls set or clear it implicitly, while
+others have API flags such as `AT_SYMLINK_FOLLOW` and
+`UMOUNT_NOFOLLOW` to control it.  Its effect is similar to
+`WALK_GET` that we already met, but it is used in a different way.
+
+`LOOKUP_DIRECTORY` insists that the final component is a directory.
+Various callers set this and it is also set when the final component
+is found to be followed by a slash.
+
+Finally `LOOKUP_OPEN`, `LOOKUP_CREATE`, `LOOKUP_EXCL`, and
+`LOOKUP_RENAME_TARGET` are not used directly by the VFS but are made
+available to the filesystem and particularly the `->d_revalidate()`
+method.  A filesystem can choose not to bother revalidating too hard
+if it knows that it will be asked to open or create the file soon.
+These flags were previously useful for `->lookup()` too but with the
+introduction of `->atomic_open()` they are less relevant there.
+
+End of the road
+---------------
+
+Despite its complexity, all this pathname lookup code appears to be
+in good shape - various parts are certainly easier to understand now
+than even a couple of releases ago.  But that doesn't mean it is
+"finished".   As already mentioned, RCU-walk currently only follows
+symlinks that are stored in the inode so, while it handles many ext4
+symlinks, it doesn't help with NFS, XFS, or Btrfs.  That support
+is not likely to be long delayed.

+FPGA Manager Core
+
+Alan Tull 2015
+
+Overview
+========
+
+The FPGA manager core exports a set of functions for programming an FPGA with
+an image.  The API is manufacturer agnostic.  All manufacturer specifics are
+hidden away in a low level driver which registers a set of ops with the core.
+The FPGA image data itself is very manufacturer specific, but for our purposes
+it's just binary data.  The FPGA manager core won't parse it.
+
+
+API Functions:
+==============
+
+To program the FPGA from a file or from a buffer:
+-------------------------------------------------
+
+	int fpga_mgr_buf_load(struct fpga_manager *mgr, u32 flags,
+		              const char *buf, size_t count);
+
+Load the FPGA from an image which exists as a buffer in memory.
+
+	int fpga_mgr_firmware_load(struct fpga_manager *mgr, u32 flags,
+		                   const char *image_name);
+
+Load the FPGA from an image which exists as a file.  The image file must be on
+the firmware search path (see the firmware class documentation).
+
+For both these functions, flags == 0 for normal full reconfiguration or
+FPGA_MGR_PARTIAL_RECONFIG for partial reconfiguration.  If successful, the FPGA
+ends up in operating mode.  Return 0 on success or a negative error code.
+
+
+To get/put a reference to a FPGA manager:
+-----------------------------------------
+
+	struct fpga_manager *of_fpga_mgr_get(struct device_node *node);
+
+	void fpga_mgr_put(struct fpga_manager *mgr);
+
+Given a DT node, get an exclusive reference to a FPGA manager or release
+the reference.
+
+
+To register or unregister the low level FPGA-specific driver:
+-------------------------------------------------------------
+
+	int fpga_mgr_register(struct device *dev, const char *name,
+		              const struct fpga_manager_ops *mops,
+		              void *priv);
+
+	void fpga_mgr_unregister(struct device *dev);
+
+Use of these two functions is described below in "How To Support a new FPGA
+device."
+
+
+How to write an image buffer to a supported FPGA
+================================================
+/* Include to get the API */
+#include <linux/fpga/fpga-mgr.h>

+#include <linux/fpga/fpga-mgr.h>
+
+/* device node that specifies the FPGA manager to use */
+struct device_node *mgr_node = ...
+
+/* FPGA image is in this file which is in the firmware search path */

+/* Get the firmware image (path) and load it to the FPGA */
+ret = fpga_mgr_firmware_load(mgr, flags, path);
+
+/* Release the FPGA manager */
+fpga_mgr_put(mgr);
+
+
+How to support a new FPGA device
+================================
+To add another FPGA manager, write a driver that implements a set of ops.  The
+probe function calls fpga_mgr_register(), such as:
+
+static const struct fpga_manager_ops socfpga_fpga_ops = {
+       .write_init = socfpga_fpga_ops_configure_init,
+       .write = socfpga_fpga_ops_configure_write,
+       .write_complete = socfpga_fpga_ops_configure_complete,
+       .state = socfpga_fpga_ops_state,
+};
+
+static int socfpga_fpga_probe(struct platform_device *pdev)
+{
+	struct device *dev = &pdev->dev;
+	struct socfpga_fpga_priv *priv;
+	int ret;
+
+	priv = devm_kzalloc(dev, sizeof(*priv), GFP_KERNEL);
+	if (!priv)
+		return -ENOMEM;
+
+	/* ... do ioremaps, get interrupts, etc. and save
+	   them in priv... */
+
+	return fpga_mgr_register(dev, "Altera SOCFPGA FPGA Manager",
+				 &socfpga_fpga_ops, priv);
+}
+
+static int socfpga_fpga_remove(struct platform_device *pdev)
+{
+	fpga_mgr_unregister(&pdev->dev);
+
+	return 0;
+}
+
+
+The ops will implement whatever device specific register writes are needed to
+do the programming sequence for this particular FPGA.  These ops return 0 for
+success or negative error codes otherwise.
+
+The programming sequence is:
+ 1. .write_init
+ 2. .write (may be called once or multiple times)
+ 3. .write_complete
+
+The .write_init function will prepare the FPGA to receive the image data.
+
+The .write function writes a buffer to the FPGA. The buffer may be contain the
+whole FPGA image or may be a smaller chunk of an FPGA image.  In the latter
+case, this function is called multiple times for successive chunks.
+
+The .write_complete function is called after all the image has been written
+to put the FPGA into operating mode.
+
+The ops include a .state function which will read the hardware FPGA manager and
+return a code of type enum fpga_mgr_states.  It doesn't result in a change in
+hardware state.

+This driver implements support for the Maxim MAX31790 chip.
+
+The MAX31790 controls the speeds of up to six fans using six independent
+PWM outputs. The desired fan speeds (or PWM duty cycles) are written
+through the I2C interface. The outputs drive "4-wire" fans directly,
+or can be used to modulate the fan's power terminals using an external
+pass transistor.
+
+Tachometer inputs monitor fan tachometer logic outputs for precise (+/-1%)
+monitoring and control of fan RPM as well as detection of fan failure.
+Six pins are dedicated tachometer inputs. Any of the six PWM outputs can
+also be configured to serve as tachometer inputs.

+--------------------------------------------------------------------------------
+
+1. Introduction
+~~~~~~~~~~~~~~~
+  This module is intended to try to make the lives of input driver developers
+easier by allowing them to test various serio devices (mainly the various
+touchpads found on laptops) without having to have the physical device in front
+of them. userio accomplishes this by allowing any privileged userspace program
+to directly interact with the kernel's serio driver and control a virtual serio
+port from there.
+
+2. Usage overview
+~~~~~~~~~~~~~~~~~
+  In order to interact with the userio kernel module, one simply opens the
+/dev/userio character device in their applications. Commands are sent to the
+kernel module by writing to the device, and any data received from the serio
+driver is read as-is from the /dev/userio device. All of the structures and
+macros you need to interact with the device are defined in <linux/userio.h> and
+<linux/serio.h>.
+
+3. Command Structure
+~~~~~~~~~~~~~~~~~~~~
+  The struct used for sending commands to /dev/userio is as follows:
+
+	struct userio_cmd {
+		__u8 type;
+		__u8 data;
+	};
+
+  "type" describes the type of command that is being sent. This can be any one
+of the USERIO_CMD macros defined in <linux/userio.h>. "data" is the argument
+that goes along with the command. In the event that the command doesn't have an
+argument, this field can be left untouched and will be ignored by the kernel.
+Each command should be sent by writing the struct directly to the character
+device. In the event that the command you send is invalid, an error will be
+returned by the character device and a more descriptive error will be printed
+to the kernel log. Only one command can be sent at a time, any additional data
+written to the character device after the initial command will be ignored.
+  To close the virtual serio port, just close /dev/userio.
+
+4. Commands
+~~~~~~~~~~~
+
+4.1 USERIO_CMD_REGISTER
+~~~~~~~~~~~~~~~~~~~~~~~
+  Registers the port with the serio driver and begins transmitting data back and
+forth. Registration can only be performed once a port type is set with
+USERIO_CMD_SET_PORT_TYPE. Has no argument.
+
+4.2 USERIO_CMD_SET_PORT_TYPE
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Sets the type of port we're emulating, where "data" is the port type being
+set. Can be any of the macros from <linux/serio.h>. For example: SERIO_8042
+would set the port type to be a normal PS/2 port.
+
+4.3 USERIO_CMD_SEND_INTERRUPT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Sends an interrupt through the virtual serio port to the serio driver, where
+"data" is the interrupt data being sent.
+
+5. Userspace tools
+~~~~~~~~~~~~~~~~~~
+  The userio userspace tools are able to record PS/2 devices using some of the
+debugging information from i8042, and play back the devices on /dev/userio. The
+latest version of these tools can be found at:

+# Test with:
+#
+# make KBUILD_KCONFIG=Documentation/kbuild/Kconfig.recursion-issue-01 allnoconfig
+#
+# This Kconfig file has a simple recursive dependency issue. In order to
+# understand why this recursive dependency issue occurs lets consider what
+# Kconfig needs to address. We iterate over what Kconfig needs to address
+# by stepping through the questions it needs to address sequentially.
+#
+#  * What values are possible for CORE?
+#
+# CORE_BELL_A_ADVANCED selects CORE, which means that it influences the values
+# that are possible for CORE. So for example if CORE_BELL_A_ADVANCED is 'y',
+# CORE must be 'y' too.
+#
+#  * What influences CORE_BELL_A_ADVANCED ?
+#
+# As the name implies CORE_BELL_A_ADVANCED is an advanced feature of
+# CORE_BELL_A so naturally it depends on CORE_BELL_A. So if CORE_BELL_A is 'y'
+# we know CORE_BELL_A_ADVANCED can be 'y' too.
+#
+#   * What influences CORE_BELL_A ?
+#
+# CORE_BELL_A depends on CORE, so CORE influences CORE_BELL_A.
+#
+# But that is a problem, because this means that in order to determine
+# what values are possible for CORE we ended up needing to address questions
+# regarding possible values of CORE itself again. Answering the original
+# question of what are the possible values of CORE would make the kconfig
+# tools run in a loop. When this happens Kconfig exits and complains about
+# the "recursive dependency detected" error.
+#
+# Reading the Documentation/kbuild/Kconfig.recursion-issue-01 file it may be
+# obvious that an easy to solution to this problem should just be the removal
+# of the "select CORE" from CORE_BELL_A_ADVANCED as that is implicit already
+# since CORE_BELL_A depends on CORE. Recursive dependency issues are not always
+# so trivial to resolve, we provide another example below of practical
+# implications of this recursive issue where the solution is perhaps not so
+# easy to understand. Note that matching semantics on the dependency on
+# CORE also consist of a solution to this recursive problem.

+# Cumulative Kconfig recursive issue
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+# Test with:
+#
+# make KBUILD_KCONFIG=Documentation/kbuild/Kconfig.recursion-issue-02 allnoconfig
+#
+# The recursive limitations with Kconfig has some non intuitive implications on
+# kconfig sematics which are documented here. One known practical implication
+# of the recursive limitation is that drivers cannot negate features from other
+# drivers if they share a common core requirement and use disjoint semantics to
+# annotate those requirements, ie, some drivers use "depends on" while others
+# use "select". For instance it means if a driver A and driver B share the same
+# core requirement, and one uses "select" while the other uses "depends on" to
+# annotate this, all features that driver A selects cannot now be negated by
+# driver B.
+#
+# A perhaps not so obvious implication of this is that, if semantics on these
+# core requirements are not carefully synced, as drivers evolve features
+# they select or depend on end up becoming shared requirements which cannot be
+# negated by other drivers.
+#
+# The example provided in Documentation/kbuild/Kconfig.recursion-issue-02
+# describes a simple driver core layout of example features a kernel might
+# have. Let's assume we have some CORE functionality, then the kernel has a
+# series of bells and whistles it desires to implement, its not so advanced so
+# it only supports bells at this time: CORE_BELL_A and CORE_BELL_B. If
+# CORE_BELL_A has some advanced feature CORE_BELL_A_ADVANCED which selects
+# CORE_BELL_A then CORE_BELL_A ends up becoming a common BELL feature which
+# other bells in the system cannot negate. The reason for this issue is
+# due to the disjoint use of semantics on expressing each bell's relationship
+# with CORE, one uses "depends on" while the other uses "select". Another
+# more important reason is that kconfig does not check for dependencies listed
+# under 'select' for a symbol, when such symbols are selected kconfig them
+# as mandatory required symbols. For more details on the heavy handed nature
+# of select refer to Documentation/kbuild/Kconfig.select-break
+#
+# To fix this the "depends on CORE" must be changed to "select CORE", or the
+# "select CORE" must be changed to "depends on CORE".
+#
+# For an example real world scenario issue refer to the attempt to remove
+# "select FW_LOADER" [0], in the end the simple alternative solution to this
+# problem consisted on matching semantics with newly introduced features.

+Kconfig recursive dependency limitations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you've hit the Kconfig error: "recursive dependency detected" you've run
+into a recursive dependency issue with Kconfig, a recursive dependency can be
+summarized as a circular dependency. The kconfig tools need to ensure that
+Kconfig files comply with specified configuration requirements. In order to do
+that kconfig must determine the values that are possible for all Kconfig
+symbols, this is currently not possible if there is a circular relation
+between two or more Kconfig symbols. For more details refer to the "Simple
+Kconfig recursive issue" subsection below. Kconfig does not do recursive
+dependency resolution; this has a few implications for Kconfig file writers.
+We'll first explain why this issues exists and then provide an example
+technical limitation which this brings upon Kconfig developers. Eager
+developers wishing to try to address this limitation should read the next
+subsections.

+Practical solutions to kconfig recursive issue
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Developers who run into the recursive Kconfig issue have three options
+at their disposal. We document them below and also provide a list of
+historical issues resolved through these different solutions.
+
+  a) Remove any superfluous "select FOO" or "depends on FOO"
+  b) Match dependency semantics:
+	b1) Swap all "select FOO" to "depends on FOO" or,
+	b2) Swap all "depends on FOO" to "select FOO"
+
+The resolution to a) can be tested with the sample Kconfig file
+Documentation/kbuild/Kconfig.recursion-issue-01 through the removal
+of the "select CORE" from CORE_BELL_A_ADVANCED as that is implicit already
+since CORE_BELL_A depends on CORE. At times it may not be possible to remove
+some dependency criteria, for such cases you can work with solution b).
+
+The two different resolutions for b) can be tested in the sample Kconfig file
+Documentation/kbuild/Kconfig.recursion-issue-02.
+
+Below is a list of examples of prior fixes for these types of recursive issues;
+all errors appear to involve one or more select's and one or more "depends on".

+
+Future kconfig work
+~~~~~~~~~~~~~~~~~~~
+
+Work on kconfig is welcomed on both areas of clarifying semantics and on
+evaluating the use of a full SAT solver for it. A full SAT solver can be
+desirable to enable more complex dependency mappings and / or queries,
+for instance on possible use case for a SAT solver could be that of handling
+the current known recursive dependency issues. It is not known if this would
+address such issues but such evaluation is desirable. If support for a full SAT
+solver proves too complex or that it cannot address recursive dependency issues
+Kconfig should have at least clear and well defined semantics which also
+addresses and documents limitations or requirements such as the ones dealing
+with recursive dependencies.
+
+Further work on both of these areas is welcomed on Kconfig. We elaborate
+on both of these in the next two subsections.
+
+Semantics of Kconfig
+~~~~~~~~~~~~~~~~~~~~
+
+The use of Kconfig is broad, Linux is now only one of Kconfig's users:
+one study has completed a broad analysis of Kconfig use in 12 projects [0].
+Despite its widespread use, and although this document does a reasonable job
+in documenting basic Kconfig syntax a more precise definition of Kconfig
+semantics is welcomed. One project deduced Kconfig semantics through
+the use of the xconfig configurator [1]. Work should be done to confirm if
+the deduced semantics matches our intended Kconfig design goals.
+
+Having well defined semantics can be useful for tools for practical
+evaluation of depenencies, for instance one such use known case was work to
+express in boolean abstraction of the inferred semantics of Kconfig to
+translate Kconfig logic into boolean formulas and run a SAT solver on this to
+find dead code / features (always inactive), 114 dead features were found in
+Linux using this methodology [1] (Section 8: Threats to validity).
+
+Confirming this could prove useful as Kconfig stands as one of the the leading
+industrial variability modeling languages [1] [2]. Its study would help
+evaluate practical uses of such languages, their use was only theoretical
+and real world requirements were not well understood. As it stands though
+only reverse engineering techniques have been used to deduce semantics from
+variability modeling languages such as Kconfig [3].

+[3] http://gsd.uwaterloo.ca/sites/default/files/icse2011.pdf
+
+Full SAT solver for Kconfig
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Although SAT solvers [0] haven't yet been used by Kconfig directly, as noted in
+the previous subsection, work has been done however to express in boolean
+abstraction the inferred semantics of Kconfig to translate Kconfig logic into
+boolean formulas and run a SAT solver on it [1]. Another known related project
+is CADOS [2] (former VAMOS [3]) and the tools, mainly undertaker [4], which has
+been introduced first with [5].  The basic concept of undertaker is to exract
+variability models from Kconfig, and put them together with a propositional
+formula extracted from CPP #ifdefs and build-rules into a SAT solver in order
+to find dead code, dead files, and dead symbols. If using a SAT solver is
+desirable on Kconfig one approach would be to evaluate repurposing such efforts
+somehow on Kconfig. There is enough interest from mentors of existing projects
+to not only help advise how to integrate this work upstream but also help
+maintain it long term. Interested developers should visit:

   The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
   N.B. CAN FD capable devices can also handle and send legacy CAN frames.
 
-  FIXME: Add details about the CAN FD controller configuration when available.
+  When configuring CAN FD capable CAN controllers an additional 'data' bitrate
+  has to be set. This bitrate for the data phase of the CAN FD frame has to be
+  at least the bitrate which was configured for the arbitration phase. This
+  second bitrate is specified analogue to the first bitrate but the bitrate
+  setting keywords for the 'data' bitrate start with 'd' e.g. dbitrate,
+  dsample-point, dsjw or dtq and similar settings. When a data bitrate is set
+  within the configuration process the controller option "fd on" can be
+  specified to enable the CAN FD mode in the CAN controller. This controller
+  option also switches the device MTU to 72 (CANFD_MTU).
+
+  The first CAN FD specification presented as whitepaper at the International
+  CAN Conference 2012 needed to be improved for data integrity reasons.
+  Therefore two CAN FD implementations have to be distinguished today:
+
+  - ISO compliant:     The ISO 11898-1:2015 CAN FD implementation (default)
+  - non-ISO compliant: The CAN FD implementation following the 2012 whitepaper
+
+  Finally there are three types of CAN FD controllers:
+
+  1. ISO compliant (fixed)
+  2. non-ISO compliant (fixed, like the M_CAN IP core v3.0.1 in m_can.c)
+  3. ISO/non-ISO CAN FD controllers (switchable, like the PEAK PCAN-USB FD)
+
+  The current ISO/non-ISO mode is announced by the CAN controller driver via
+  netlink and displayed by the 'ip' tool (controller option FD-NON-ISO).
+  The ISO/non-ISO-mode can be altered by setting 'fd-non-iso {on|off}' for
+  switchable CAN FD controllers only.
+
+  Example configuring 500 kbit/s arbitration bitrate and 4 Mbit/s data bitrate:

+
+Using iproute2 for VRFs
+=======================
+VRF devices do *not* have to start with 'vrf-'. That is a convention used here
+for emphasis of the device type, similar to use of 'br' in bridge names.
+
+1. Create a VRF
+
+   To instantiate a VRF device and associate it with a table:
+       $ ip link add dev NAME type vrf table ID
+
+   Remember to add the ip rules as well:
+       $ ip ru add oif NAME table 10
+       $ ip ru add iif NAME table 10
+       $ ip -6 ru add oif NAME table 10
+       $ ip -6 ru add iif NAME table 10
+
+   Without the rules route lookups are not directed to the table.
+
+   For example:
+   $ ip link add dev vrf-blue type vrf table 10
+   $ ip ru add pref 200 oif vrf-blue table 10
+   $ ip ru add pref 200 iif vrf-blue table 10
+   $ ip -6 ru add pref 200 oif vrf-blue table 10
+   $ ip -6 ru add pref 200 iif vrf-blue table 10
+
+
+2. List VRFs
+
+   To list VRFs that have been created:
+       $ ip [-d] link show type vrf
+         NOTE: The -d option is needed to show the table id
+
+   For example:
+   $ ip -d link show type vrf
+   11: vrf-mgmt: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether 72:b3:ba:91:e2:24 brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 1 addrgenmode eui64
+   12: vrf-red: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether b6:6f:6e:f6:da:73 brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 10 addrgenmode eui64
+   13: vrf-blue: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether 36:62:e8:7d:bb:8c brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 66 addrgenmode eui64
+   14: vrf-green: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether e6:28:b8:63:70:bb brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 81 addrgenmode eui64
+
+
+   Or in brief output:
+
+   $ ip -br link show type vrf
+   vrf-mgmt         UP             72:b3:ba:91:e2:24 <NOARP,MASTER,UP,LOWER_UP>
+   vrf-red          UP             b6:6f:6e:f6:da:73 <NOARP,MASTER,UP,LOWER_UP>
+   vrf-blue         UP             36:62:e8:7d:bb:8c <NOARP,MASTER,UP,LOWER_UP>
+   vrf-green        UP             e6:28:b8:63:70:bb <NOARP,MASTER,UP,LOWER_UP>
+
+
+3. Assign a Network Interface to a VRF
+
+   Network interfaces are assigned to a VRF by enslaving the netdevice to a
+   VRF device:
+       $ ip link set dev NAME master VRF-NAME
+
+   On enslavement connected and local routes are automatically moved to the
+   table associated with the VRF device.
+
+   For example:
+   $ ip link set dev eth0 master vrf-mgmt
+
+
+4. Show Devices Assigned to a VRF
+
+   To show devices that have been assigned to a specific VRF add the master
+   option to the ip command:
+       $ ip link show master VRF-NAME
+
+   For example:
+   $ ip link show master vrf-red
+   3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
+       link/ether 02:00:00:00:02:02 brd ff:ff:ff:ff:ff:ff
+   4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
+       link/ether 02:00:00:00:02:03 brd ff:ff:ff:ff:ff:ff
+   7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master vrf-red state DOWN mode DEFAULT group default qlen 1000
+       link/ether 02:00:00:00:02:06 brd ff:ff:ff:ff:ff:ff
+
+
+   Or using the brief output:
+   $ ip -br link show master vrf-red
+   eth1             UP             02:00:00:00:02:02 <BROADCAST,MULTICAST,UP,LOWER_UP>
+   eth2             UP             02:00:00:00:02:03 <BROADCAST,MULTICAST,UP,LOWER_UP>
+   eth5             DOWN           02:00:00:00:02:06 <BROADCAST,MULTICAST>
+
+
+5. Show Neighbor Entries for a VRF
+
+   To list neighbor entries associated with devices enslaved to a VRF device
+   add the master option to the ip command:
+       $ ip [-6] neigh show master VRF-NAME
+
+   For example:
+   $  ip neigh show master vrf-red
+   10.2.1.254 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
+   10.2.2.254 dev eth2 lladdr 5e:54:01:6a:ee:80 REACHABLE
+
+    $ ip -6 neigh show master vrf-red
+    2002:1::64 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
+
+
+6. Show Addresses for a VRF
+
+   To show addresses for interfaces associated with a VRF add the master
+   option to the ip command:
+       $ ip addr show master VRF-NAME
+
+   For example:
+   $ ip addr show master vrf-red
+   3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP group default qlen 1000
+       link/ether 02:00:00:00:02:02 brd ff:ff:ff:ff:ff:ff
+       inet 10.2.1.2/24 brd 10.2.1.255 scope global eth1

+   4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP group default qlen 1000
+       link/ether 02:00:00:00:02:03 brd ff:ff:ff:ff:ff:ff
+       inet 10.2.2.2/24 brd 10.2.2.255 scope global eth2
+          valid_lft forever preferred_lft forever
+       inet6 2002:2::2/120 scope global
+          valid_lft forever preferred_lft forever
+       inet6 fe80::ff:fe00:203/64 scope link
+          valid_lft forever preferred_lft forever
+   7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master vrf-red state DOWN group default qlen 1000
+       link/ether 02:00:00:00:02:06 brd ff:ff:ff:ff:ff:ff
+
+   Or in brief format:
+   $ ip -br addr show master vrf-red
+   eth1             UP             10.2.1.2/24 2002:1::2/120 fe80::ff:fe00:202/64
+   eth2             UP             10.2.2.2/24 2002:2::2/120 fe80::ff:fe00:203/64
+   eth5             DOWN
+
+
+7. Show Routes for a VRF
+
+   To show routes for a VRF use the ip command to display the table associated
+   with the VRF device:
+       $ ip [-6] route show table ID
+
+   For example:
+   $ ip route show table vrf-red
+   prohibit default
+   broadcast 10.2.1.0 dev eth1  proto kernel  scope link  src 10.2.1.2
+   10.2.1.0/24 dev eth1  proto kernel  scope link  src 10.2.1.2
+   local 10.2.1.2 dev eth1  proto kernel  scope host  src 10.2.1.2
+   broadcast 10.2.1.255 dev eth1  proto kernel  scope link  src 10.2.1.2
+   broadcast 10.2.2.0 dev eth2  proto kernel  scope link  src 10.2.2.2
+   10.2.2.0/24 dev eth2  proto kernel  scope link  src 10.2.2.2
+   local 10.2.2.2 dev eth2  proto kernel  scope host  src 10.2.2.2
+   broadcast 10.2.2.255 dev eth2  proto kernel  scope link  src 10.2.2.2
+
+   $ ip -6 route show table vrf-red
+   local 2002:1:: dev lo  proto none  metric 0  pref medium
+   local 2002:1::2 dev lo  proto none  metric 0  pref medium
+   2002:1::/120 dev eth1  proto kernel  metric 256  pref medium
+   local 2002:2:: dev lo  proto none  metric 0  pref medium
+   local 2002:2::2 dev lo  proto none  metric 0  pref medium

+   local fe80:: dev lo  proto none  metric 0  pref medium
+   local fe80:: dev lo  proto none  metric 0  pref medium
+   local fe80::ff:fe00:202 dev lo  proto none  metric 0  pref medium
+   local fe80::ff:fe00:203 dev lo  proto none  metric 0  pref medium
+   fe80::/64 dev eth1  proto kernel  metric 256  pref medium
+   fe80::/64 dev eth2  proto kernel  metric 256  pref medium
+   ff00::/8 dev vrf-red  metric 256  pref medium
+   ff00::/8 dev eth1  metric 256  pref medium
+   ff00::/8 dev eth2  metric 256  pref medium
+
+
+8. Route Lookup for a VRF
+
+   A test route lookup can be done for a VRF by adding the oif option to ip:
+       $ ip [-6] route get oif VRF-NAME ADDRESS
+
+   For example:
+   $ ip route get 10.2.1.40 oif vrf-red
+   10.2.1.40 dev eth1  table vrf-red  src 10.2.1.2
+       cache
+
+   $ ip -6 route get 2002:1::32 oif vrf-red
+   2002:1::32 from :: dev eth1  table vrf-red  proto kernel  src 2002:1::2  metric 256  pref medium
+
+
+9. Removing Network Interface from a VRF
+
+   Network interfaces are removed from a VRF by breaking the enslavement to
+   the VRF device:
+       $ ip link set dev NAME nomaster
+
+   Connected routes are moved back to the default table and local entries are
+   moved to the local table.
+
+   For example:
+   $ ip link set dev eth0 nomaster
+

-Initialization of Bus Instance
-==============================
-
-The card driver has to create struct hda_bus at first.  The template
-struct should be filled and passed to the constructor:
-
-struct hda_bus_template {
-	void *private_data;
-	struct pci_dev *pci;
-	const char *modelname;
-	struct hda_bus_ops ops;
-};
-
-The card driver can set and use the private_data field to retrieve its
-own data in callback functions.  The pci field is used when the patch
-needs to check the PCI subsystem IDs, so on.  For non-PCI system, it
-doesn't have to be set, of course.
-The modelname field specifies the board's specific configuration.  The
-string is passed to the codec parser, and it depends on the parser how
-the string is used.
-These fields, private_data, pci and modelname are all optional.
-
-The ops field contains the callback functions as the following:
-
-struct hda_bus_ops {
-	int (*command)(struct hda_codec *codec, hda_nid_t nid, int direct,
-		       unsigned int verb, unsigned int parm);
-	unsigned int (*get_response)(struct hda_codec *codec);
-	void (*private_free)(struct hda_bus *);
-#ifdef CONFIG_SND_HDA_POWER_SAVE
-	void (*pm_notify)(struct hda_codec *codec);
-#endif
-};
-
-The command callback is called when the codec module needs to send a
-VERB to the controller.  It's always a single command.
-The get_response callback is called when the codec requires the answer
-for the last command.  These two callbacks are mandatory and have to
-be given.
-The third, private_free callback, is optional.  It's called in the
-destructor to release any necessary data in the lowlevel driver.
-
-The pm_notify callback is available only with
-CONFIG_SND_HDA_POWER_SAVE kconfig.  It's called when the codec needs
-to power up or may power down.  The controller should check the all
-belonging codecs on the bus whether they are actually powered off
-(check codec->power_on), and optionally the driver may power down the
-controller side, too.
-
-The bus instance is created via snd_hda_bus_new().  You need to pass
-the card instance, the template, and the pointer to store the
-resultant bus instance.
-
-int snd_hda_bus_new(struct snd_card *card, const struct hda_bus_template *temp,
-		    struct hda_bus **busp);
-
-It returns zero if successful.  A negative return value means any
-error during creation.
-
-
-Creation of Codec Instance
-==========================
-
-Each codec chip on the board is then created on the BUS instance.
-To create a codec instance, call snd_hda_codec_new().
-
-int snd_hda_codec_new(struct hda_bus *bus, unsigned int codec_addr,
-		      struct hda_codec **codecp);
-
-The first argument is the BUS instance, the second argument is the
-address of the codec, and the last one is the pointer to store the
-resultant codec instance (can be NULL if not needed).
-
-The codec is stored in a linked list of bus instance.  You can follow
-the codec list like:
-
-	struct hda_codec *codec;
-	list_for_each_entry(codec, &bus->codec_list, list) {
-		...
-	}
-
-The codec isn't initialized at this stage properly.  The
-initialization sequence is called when the controls are built later.
-
-
-Codec Access
-============
-
-To access codec, use snd_hda_codec_read() and snd_hda_codec_write().
-snd_hda_param_read() is for reading parameters.
-For writing a sequence of verbs, use snd_hda_sequence_write().
-
-There are variants of cached read/write, snd_hda_codec_write_cache(),
-snd_hda_sequence_write_cache().  These are used for recording the
-register states for the power-management resume.  When no PM is needed,
-these are equivalent with non-cached version.
-
-To retrieve the number of sub nodes connected to the given node, use
-snd_hda_get_sub_nodes().  The connection list can be obtained via
-snd_hda_get_connections() call.
-
-When an unsolicited event happens, pass the event via
-snd_hda_queue_unsol_event() so that the codec routines will process it
-later.
-
-
-(Mixer) Controls
-================
-
-To create mixer controls of all codecs, call
-snd_hda_build_controls().  It then builds the mixers and does
-initialization stuff on each codec.
-
-
-PCM Stuff
-=========
-
-snd_hda_build_pcms() gives the necessary information to create PCM
-streams.  When it's called, each codec belonging to the bus stores 
-codec->num_pcms and codec->pcm_info fields.  The num_pcms indicates
-the number of elements in pcm_info array.  The card driver is supposed
-to traverse the codec linked list, read the pcm information in
-pcm_info array, and build pcm instances according to them. 
-
-The pcm_info array contains the following record:
-
-/* PCM information for each substream */
-struct hda_pcm_stream {
-	unsigned int substreams;	/* number of substreams, 0 = not exist */
-	unsigned int channels_min;	/* min. number of channels */
-	unsigned int channels_max;	/* max. number of channels */
-	hda_nid_t nid;	/* default NID to query rates/formats/bps, or set up */
-	u32 rates;	/* supported rates */
-	u64 formats;	/* supported formats (SNDRV_PCM_FMTBIT_) */
-	unsigned int maxbps;	/* supported max. bit per sample */
-	struct hda_pcm_ops ops;
-};
-
-/* for PCM creation */
-struct hda_pcm {
-	char *name;
-	struct hda_pcm_stream stream[2];
-};
-
-The name can be passed to snd_pcm_new().  The stream field contains
-the information  for playback (SNDRV_PCM_STREAM_PLAYBACK = 0) and
-capture (SNDRV_PCM_STREAM_CAPTURE = 1) directions.  The card driver
-should pass substreams to snd_pcm_new() for the number of substreams
-to create.
-
-The channels_min, channels_max, rates and formats should be copied to
-runtime->hw record.  They and maxbps fields are used also to compute
-the format value for the HDA codec and controller.  Call
-snd_hda_calc_stream_format() to get the format value.
-
-The ops field contains the following callback functions:
-
-struct hda_pcm_ops {
-	int (*open)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		    struct snd_pcm_substream *substream);
-	int (*close)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		     struct snd_pcm_substream *substream);
-	int (*prepare)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		       unsigned int stream_tag, unsigned int format,
-		       struct snd_pcm_substream *substream);
-	int (*cleanup)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		       struct snd_pcm_substream *substream);
-};
-
-All are non-NULL, so you can call them safely without NULL check.
-
-The open callback should be called in PCM open after runtime->hw is
-set up.  It may override some setting and constraints additionally.
-Similarly, the close callback should be called in the PCM close.
-
-The prepare callback should be called in PCM prepare.  This will set
-up the codec chip properly for the operation.  The cleanup should be
-called in hw_free to clean up the configuration.
-
-The caller should check the return value, at least for open and
-prepare callbacks.  When a negative value is returned, some error
-occurred.
-
-
-Proc Files
-==========
-
-Each codec dumps the widget node information in
-/proc/asound/card*/codec#* file.  This information would be really
-helpful for debugging.  Please provide its contents together with the
-bug report.
-
-
-Power Management
-================
-
-It's simple:
-Call snd_hda_suspend() in the PM suspend callback.
-Call snd_hda_resume() in the PM resume callback.
-
-
-Codec Preset (Patch)
-====================
-
-To set up and handle the codec functionality fully, each codec may
-have a codec preset (patch).  It's defined in struct hda_codec_preset:
-
-	struct hda_codec_preset {
-		unsigned int id;
-		unsigned int mask;
-		unsigned int subs;
-		unsigned int subs_mask;
-		unsigned int rev;
-		const char *name;
-		int (*patch)(struct hda_codec *codec);
-	};
-
-When the codec id and codec subsystem id match with the given id and
-subs fields bitwise (with bitmask mask and subs_mask), the callback
-patch is called.  The patch callback should initialize the codec and
-set the codec->patch_ops field.  This is defined as below:
-
-	struct hda_codec_ops {
-		int (*build_controls)(struct hda_codec *codec);
-		int (*build_pcms)(struct hda_codec *codec);
-		int (*init)(struct hda_codec *codec);
-		void (*free)(struct hda_codec *codec);
-		void (*unsol_event)(struct hda_codec *codec, unsigned int res);
-	#ifdef CONFIG_PM
-		int (*suspend)(struct hda_codec *codec, pm_message_t state);
-		int (*resume)(struct hda_codec *codec);
-	#endif
-	#ifdef CONFIG_SND_HDA_POWER_SAVE
-		int (*check_power_status)(struct hda_codec *codec,
-					  hda_nid_t nid);
-	#endif
-	};
-
-The build_controls callback is called from snd_hda_build_controls().
-Similarly, the build_pcms callback is called from
-snd_hda_build_pcms().  The init callback is called after
-build_controls to initialize the hardware.
-The free callback is called as a destructor.
-
-The unsol_event callback is called when an unsolicited event is
-received.
-
-The suspend and resume callbacks are for power management.
-They can be NULL if no special sequence is required.  When the resume
-callback is NULL, the driver calls the init callback and resumes the
-registers from the cache.  If other handling is needed, you'd need to
-write your own resume callback.  There, the amp values can be resumed
-via
-	void snd_hda_codec_resume_amp(struct hda_codec *codec);
-and the other codec registers via
-	void snd_hda_codec_resume_cache(struct hda_codec *codec);
-
-The check_power_status callback is called when the amp value of the
-given widget NID is changed.  The codec code can turn on/off the power
-appropriately from this information.
-
-Each entry can be NULL if not necessary to be called.
-
-
-Generic Parser
-==============
-
-When the device doesn't match with any given presets, the widgets are
-parsed via th generic parser (hda_generic.c).  Its support is
-limited: no multi-channel support, for example.
-
-
-Digital I/O
-===========
-
-Call snd_hda_create_spdif_out_ctls() from the patch to create controls
-related with SPDIF out.
-
-
-Helper Functions
-================
-
-snd_hda_get_codec_name() stores the codec name on the given string.
-
-snd_hda_check_board_config() can be used to obtain the configuration
-information matching with the device.  Define the model string table
-and the table with struct snd_pci_quirk entries (zero-terminated),
-and pass it to the function.  The function checks the modelname given
-as a module parameter, and PCI subsystem IDs.  If the matching entry
-is found, it returns the config field value.
-
-snd_hda_add_new_ctls() can be used to create and add control entries.
-Pass the zero-terminated array of struct snd_kcontrol_new
-
-Macros HDA_CODEC_VOLUME(), HDA_CODEC_MUTE() and their variables can be
-used for the entry of struct snd_kcontrol_new.
-
-The input MUX helper callbacks for such a control are provided, too:
-snd_hda_input_mux_info() and snd_hda_input_mux_put().  See
-patch_realtek.c for example.

+Intel(R) Trace Hub (TH)
+=======================
+
+Overview
+--------
+
+Intel(R) Trace Hub (TH) is a set of hardware blocks that produce,
+switch and output trace data from multiple hardware and software
+sources over several types of trace output ports encoded in System
+Trace Protocol (MIPI STPv2) and is intended to perform full system
+debugging. For more information on the hardware, see Intel(R) Trace
+Hub developer's manual [1].
+
+It consists of trace sources, trace destinations (outputs) and a
+switch (Global Trace Hub, GTH). These devices are placed on a bus of
+their own ("intel_th"), where they can be discovered and configured
+via sysfs attributes.
+
+Currently, the following Intel TH subdevices (blocks) are supported:
+  - Software Trace Hub (STH), trace source, which is a System Trace
+  Module (STM) device,
+  - Memory Storage Unit (MSU), trace output, which allows storing
+  trace hub output in system memory,
+  - Parallel Trace Interface output (PTI), trace output to an external
+  debug host via a PTI port,
+  - Global Trace Hub (GTH), which is a switch and a central component
+  of Intel(R) Trace Hub architecture.
+
+Common attributes for output devices are described in
+Documentation/ABI/testing/sysfs-bus-intel_th-output-devices, the most
+notable of them is "active", which enables or disables trace output
+into that particular output device.
+
+GTH allows directing different STP masters into different output ports
+via its "masters" attribute group. More detailed GTH interface
+description is at Documentation/ABI/testing/sysfs-bus-intel_th-devices-gth.
+
+STH registers an stm class device, through which it provides interface
+to userspace and kernelspace software trace sources. See
+Documentation/tracing/stm.txt for more information on that.
+
+MSU can be configured to collect trace data into a system memory
+buffer, which can later on be read from its device nodes via read() or
+mmap() interface.
+
+On the whole, Intel(R) Trace Hub does not require any special
+userspace software to function; everything can be configured, started
+and collected via sysfs attributes, and device nodes.
+
+[1] https://software.intel.com/sites/default/files/managed/d3/3c/intel-th-developer-manual.pdf
+
+Bus and Subdevices
+------------------
+
+For each Intel TH device in the system a bus of its own is
+created and assigned an id number that reflects the order in which TH
+devices were emumerated. All TH subdevices (devices on intel_th bus)
+begin with this id: 0-gth, 0-msc0, 0-msc1, 0-pti, 0-sth, which is
+followed by device's name and an optional index.
+
+Output devices also get a device node in /dev/intel_thN, where N is
+the Intel TH device id. For example, MSU's memory buffers, when
+allocated, are accessible via /dev/intel_th0/msc{0,1}.
+
+Quick example
+-------------
+
+# figure out which GTH port is the first memory controller:
+
+$ cat /sys/bus/intel_th/devices/0-msc0/port
+0
+
+# looks like it's port 0, configure master 33 to send data to port 0:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-gth/masters/33
+
+# allocate a 2-windowed multiblock buffer on the first memory
+# controller, each with 64 pages:
+
+$ echo multi > /sys/bus/intel_th/devices/0-msc0/mode
+$ echo 64,64 > /sys/bus/intel_th/devices/0-msc0/nr_pages
+
+# enable wrapping for this controller, too:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/wrap
+
+# and enable tracing into this port:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/active
+
+# .. send data to master 33, see stm.txt for more details ..
+# .. wait for traces to pile up ..
+# .. and stop the trace:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-msc0/active
+
+# and now you can collect the trace from the device node:
+
+$ cat /dev/intel_th0/msc0 > my_stp_trace

+System Trace Module
+===================
+
+System Trace Module (STM) is a device described in MIPI STP specs as
+STP trace stream generator. STP (System Trace Protocol) is a trace
+protocol multiplexing data from multiple trace sources, each one of
+which is assigned a unique pair of master and channel. While some of
+these masters and channels are statically allocated to certain
+hardware trace sources, others are available to software. Software
+trace sources are usually free to pick for themselves any
+master/channel combination from this pool.
+
+On the receiving end of this STP stream (the decoder side), trace
+sources can only be identified by master/channel combination, so in
+order for the decoder to be able to make sense of the trace that
+involves multiple trace sources, it needs to be able to map those
+master/channel pairs to the trace sources that it understands.
+
+For instance, it is helpful to know that syslog messages come on
+master 7 channel 15, while arbitrary user applications can use masters
+48 to 63 and channels 0 to 127.
+
+To solve this mapping problem, stm class provides a policy management
+mechanism via configfs, that allows defining rules that map string
+identifiers to ranges of masters and channels. If these rules (policy)
+are consistent with what decoder expects, it will be able to properly
+process the trace data.
+
+This policy is a tree structure containing rules (policy_node) that
+have a name (string identifier) and a range of masters and channels
+associated with it, located in "stp-policy" subsystem directory in
+configfs. The topmost directory's name (the policy) is formatted as
+the STM device name to which this policy applies and and arbitrary
+string identifier separated by a stop. From the examle above, a rule
+may look like this:
+
+$ ls /config/stp-policy/dummy_stm.my-policy/user
+channels masters
+$ cat /config/stp-policy/dummy_stm.my-policy/user/masters
+48 63
+$ cat /config/stp-policy/dummy_stm.my-policy/user/channels
+0 127
+
+which means that the master allocation pool for this rule consists of
+masters 48 through 63 and channel allocation pool has channels 0
+through 127 in it. Now, any producer (trace source) identifying itself
+with "user" identification string will be allocated a master and
+channel from within these ranges.
+
+These rules can be nested, for example, one can define a rule "dummy"
+under "user" directory from the example above and this new rule will
+be used for trace sources with the id string of "user/dummy".
+
+Trace sources have to open the stm class device's node and write their
+trace data into its file descriptor. In order to identify themselves
+to the policy, they need to do a STP_POLICY_ID_SET ioctl on this file
+descriptor providing their id string. Otherwise, they will be
+automatically allocated a master/channel pair upon first write to this
+file descriptor according to the "default" rule of the policy, if such
+exists.
+
+Some STM devices may allow direct mapping of the channel mmio regions
+to userspace for zero-copy writing. One mappable page (in terms of
+mmu) will usually contain multiple channels' mmios, so the user will
+need to allocate that many channels to themselves (via the
+aforementioned ioctl() call) to be able to do this. That is, if your
+stm device's channel mmio region is 64 bytes and hardware page size is
+4096 bytes, after a successful STP_POLICY_ID_SET ioctl() call with
+width==64, you should be able to mmap() one page on this file
+descriptor and obtain direct access to an mmio region for 64 channels.
+
+For kernel-based trace sources, there is "stm_source" device
+class. Devices of this class can be connected and disconnected to/from
+stm devices at runtime via a sysfs attribute.
+
+Examples of STM devices are Intel(R) Trace Hub [1] and Coresight STM
+[2].

+Interface authorization
+-----------------------
+There is a similar approach to allow or deny specific USB interfaces.
+That allows to block only a subset of an USB device.
+
+Authorize an interface:

+

+
+Deny interfaces per default:
+$ echo 0 > /sys/bus/usb/devices/usbX/interface_authorized_default
+
+Per default the interface_authorized_default bit is 1.
+So all interfaces would authorized per default.
+
+Note:
+If a deauthorized interface will be authorized so the driver probing must
+be triggered manually by writing INTERFACE to /sys/bus/usb/drivers_probe
+
+For drivers that need multiple interfaces all needed interfaces should be
+authroized first. After that the drivers should be probed.
+This avoids side effects.

+KVM/ARM VGIC Forwarded Physical Interrupts
+==========================================
+
+The KVM/ARM code implements software support for the ARM Generic
+Interrupt Controller's (GIC's) hardware support for virtualization by
+allowing software to inject virtual interrupts to a VM, which the guest
+OS sees as regular interrupts.  The code is famously known as the VGIC.
+
+Some of these virtual interrupts, however, correspond to physical
+interrupts from real physical devices.  One example could be the
+architected timer, which itself supports virtualization, and therefore
+lets a guest OS program the hardware device directly to raise an
+interrupt at some point in time.  When such an interrupt is raised, the
+host OS initially handles the interrupt and must somehow signal this
+event as a virtual interrupt to the guest.  Another example could be a
+passthrough device, where the physical interrupts are initially handled
+by the host, but the device driver for the device lives in the guest OS
+and KVM must therefore somehow inject a virtual interrupt on behalf of
+the physical one to the guest OS.
+
+These virtual interrupts corresponding to a physical interrupt on the
+host are called forwarded physical interrupts, but are also sometimes
+referred to as 'virtualized physical interrupts' and 'mapped interrupts'.
+
+Forwarded physical interrupts are handled slightly differently compared
+to virtual interrupts generated purely by a software emulated device.
+
+
+The HW bit
+----------
+Virtual interrupts are signalled to the guest by programming the List
+Registers (LRs) on the GIC before running a VCPU.  The LR is programmed
+with the virtual IRQ number and the state of the interrupt (Pending,
+Active, or Pending+Active).  When the guest ACKs and EOIs a virtual
+interrupt, the LR state moves from Pending to Active, and finally to
+inactive.
+
+The LRs include an extra bit, called the HW bit.  When this bit is set,
+KVM must also program an additional field in the LR, the physical IRQ
+number, to link the virtual with the physical IRQ.
+
+When the HW bit is set, KVM must EITHER set the Pending OR the Active
+bit, never both at the same time.
+
+Setting the HW bit causes the hardware to deactivate the physical
+interrupt on the physical distributor when the guest deactivates the
+corresponding virtual interrupt.
+
+
+Forwarded Physical Interrupts Life Cycle
+----------------------------------------
+
+The state of forwarded physical interrupts is managed in the following way:
+
+  - The physical interrupt is acked by the host, and becomes active on
+    the physical distributor (*).
+  - KVM sets the LR.Pending bit, because this is the only way the GICV
+    interface is going to present it to the guest.
+  - LR.Pending will stay set as long as the guest has not acked the interrupt.
+  - LR.Pending transitions to LR.Active on the guest read of the IAR, as
+    expected.
+  - On guest EOI, the *physical distributor* active bit gets cleared,
+    but the LR.Active is left untouched (set).
+  - KVM clears the LR on VM exits when the physical distributor
+    active state has been cleared.
+
+(*): The host handling is slightly more complicated.  For some forwarded
+interrupts (shared), KVM directly sets the active state on the physical
+distributor before entering the guest, because the interrupt is never actually
+handled on the host (see details on the timer as an example below).  For other
+forwarded interrupts (non-shared) the host does not deactivate the interrupt
+when the host ISR completes, but leaves the interrupt active until the guest
+deactivates it.  Leaving the interrupt active is allowed, because Linux
+configures the physical GIC with EOIMode=1, which causes EOI operations to
+perform a priority drop allowing the GIC to receive other interrupts of the
+default priority.
+
+
+Forwarded Edge and Level Triggered PPIs and SPIs
+------------------------------------------------
+Forwarded physical interrupts injected should always be active on the
+physical distributor when injected to a guest.
+
+Level-triggered interrupts will keep the interrupt line to the GIC
+asserted, typically until the guest programs the device to deassert the
+line.  This means that the interrupt will remain pending on the physical
+distributor until the guest has reprogrammed the device.  Since we
+always run the VM with interrupts enabled on the CPU, a pending
+interrupt will exit the guest as soon as we switch into the guest,
+preventing the guest from ever making progress as the process repeats
+over and over.  Therefore, the active state on the physical distributor
+must be set when entering the guest, preventing the GIC from forwarding
+the pending interrupt to the CPU.  As soon as the guest deactivates the
+interrupt, the physical line is sampled by the hardware again and the host
+takes a new interrupt if and only if the physical line is still asserted.
+
+Edge-triggered interrupts do not exhibit the same problem with
+preventing guest execution that level-triggered interrupts do.  One
+option is to not use HW bit at all, and inject edge-triggered interrupts
+from a physical device as pure virtual interrupts.  But that would
+potentially slow down handling of the interrupt in the guest, because a
+physical interrupt occurring in the middle of the guest ISR would
+preempt the guest for the host to handle the interrupt.  Additionally,
+if you configure the system to handle interrupts on a separate physical
+core from that running your VCPU, you still have to interrupt the VCPU
+to queue the pending state onto the LR, even though the guest won't use
+this information until the guest ISR completes.  Therefore, the HW
+bit should always be set for forwarded edge-triggered interrupts.  With
+the HW bit set, the virtual interrupt is injected and additional
+physical interrupts occurring before the guest deactivates the interrupt
+simply mark the state on the physical distributor as Pending+Active.  As
+soon as the guest deactivates the interrupt, the host takes another
+interrupt if and only if there was a physical interrupt between injecting
+the forwarded interrupt to the guest and the guest deactivating the
+interrupt.
+
+Consequently, whenever we schedule a VCPU with one or more LRs with the
+HW bit set, the interrupt must also be active on the physical
+distributor.
+
+
+Forwarded LPIs
+--------------
+LPIs, introduced in GICv3, are always edge-triggered and do not have an
+active state.  They become pending when a device signal them, and as
+soon as they are acked by the CPU, they are inactive again.
+
+It therefore doesn't make sense, and is not supported, to set the HW bit
+for physical LPIs that are forwarded to a VM as virtual interrupts,
+typically virtual SPIs.
+
+For LPIs, there is no other choice than to preempt the VCPU thread if
+necessary, and queue the pending state onto the LR.
+
+
+Putting It Together: The Architected Timer
+------------------------------------------
+The architected timer is a device that signals interrupts with level
+triggered semantics.  The timer hardware is directly accessed by VCPUs
+which program the timer to fire at some point in time.  Each VCPU on a
+system programs the timer to fire at different times, and therefore the
+hardware is multiplexed between multiple VCPUs.  This is implemented by
+context-switching the timer state along with each VCPU thread.
+
+However, this means that a scenario like the following is entirely
+possible, and in fact, typical:
+
+1.  KVM runs the VCPU
+2.  The guest programs the time to fire in T+100
+3.  The guest is idle and calls WFI (wait-for-interrupts)
+4.  The hardware traps to the host
+5.  KVM stores the timer state to memory and disables the hardware timer
+6.  KVM schedules a soft timer to fire in T+(100 - time since step 2)
+7.  KVM puts the VCPU thread to sleep (on a waitqueue)
+8.  The soft timer fires, waking up the VCPU thread
+9.  KVM reprograms the timer hardware with the VCPU's values
+10. KVM marks the timer interrupt as active on the physical distributor
+11. KVM injects a forwarded physical interrupt to the guest
+12. KVM runs the VCPU
+
+Notice that KVM injects a forwarded physical interrupt in step 11 without
+the corresponding interrupt having actually fired on the host.  That is
+exactly why we mark the timer interrupt as active in step 10, because
+the active state on the physical distributor is part of the state
+belonging to the timer hardware, which is context-switched along with
+the VCPU thread.
+
+If the guest does not idle because it is busy, the flow looks like this
+instead:
+
+1.  KVM runs the VCPU
+2.  The guest programs the time to fire in T+100
+4.  At T+100 the timer fires and a physical IRQ causes the VM to exit
+    (note that this initially only traps to EL2 and does not run the host ISR
+    until KVM has returned to the host).
+5.  With interrupts still disabled on the CPU coming back from the guest, KVM
+    stores the virtual timer state to memory and disables the virtual hw timer.
+6.  KVM looks at the timer state (in memory) and injects a forwarded physical
+    interrupt because it concludes the timer has expired.
+7.  KVM marks the timer interrupt as active on the physical distributor
+7.  KVM enables the timer, enables interrupts, and runs the VCPU
+
+Notice that again the forwarded physical interrupt is injected to the
+guest without having actually been handled on the host.  In this case it
+is because the physical interrupt is never actually seen by the host because the
+timer is disabled upon guest return, and the virtual forwarded interrupt is
+injected on the KVM guest entry path.

-There are two reasons to be requesting non __GFP_WAIT allocations:
-the caller can not sleep (typically intr context), or does not want
-to incur cost overheads of page stealing and possible swap io for
-whatever reasons.
+The first reason why a caller may avoid reclaim is that the caller can not
+sleep due to holding a spinlock or is in interrupt context. The second may
+be that the caller is willing to fail the allocation without incurring the
+overhead of page reclaim. This may happen for opportunistic high-order
+allocation requests that have order-0 fallback options. In such cases,
+the caller may also wish to avoid waking kswapd.
 
 __GFP_IO allocation requests are made to prevent file system deadlocks.

+Extended slabinfo mode and plotting
+-----------------------------------
+
+The slabinfo tool has a special 'extended' ('-X') mode that includes:
+ - Slabcache Totals
+ - Slabs sorted by size (up to -N <num> slabs, default 1)
+ - Slabs sorted by loss (up to -N <num> slabs, default 1)
+
+Additionally, in this mode slabinfo does not dynamically scale sizes (G/M/K)
+and reports everything in bytes (this functionality is also available to
+other slabinfo modes via '-B' option) which makes reporting more precise and
+accurate. Moreover, in some sense the `-X' mode also simplifies the analysis
+of slabs' behaviour, because its output can be plotted using the
+slabinfo-gnuplot.sh script. So it pushes the analysis from looking through
+the numbers (tons of numbers) to something easier -- visual analysis.
+
+To generate plots:
+a) collect slabinfo extended records, for example:
+
+  while [ 1 ]; do slabinfo -X >> FOO_STATS; sleep 1; done
+
+b) pass stats file(-s) to slabinfo-gnuplot.sh script:
+  slabinfo-gnuplot.sh FOO_STATS [FOO_STATS2 .. FOO_STATSN]
+
+The slabinfo-gnuplot.sh script will pre-processes the collected records
+and generates 3 png files (and 3 pre-processing cache files) per STATS
+file:
+ - Slabcache Totals: FOO_STATS-totals.png
+ - Slabs sorted by size: FOO_STATS-slabs-by-size.png
+ - Slabs sorted by loss: FOO_STATS-slabs-by-loss.png
+
+Another use case, when slabinfo-gnuplot can be useful, is when you need
+to compare slabs' behaviour "prior to" and "after" some code modification.
+To help you out there, slabinfo-gnuplot.sh script can 'merge' the
+`Slabcache Totals` sections from different measurements. To visually
+compare N plots:
+
+a) Collect as many STATS1, STATS2, .. STATSN files as you need
+  while [ 1 ]; do slabinfo -X >> STATS<X>; sleep 1; done
+
+b) Pre-process those STATS files
+  slabinfo-gnuplot.sh STATS1 STATS2 .. STATSN
+
+c) Execute slabinfo-gnuplot.sh in '-t' mode, passing all of the
+generated pre-processed *-totals
+  slabinfo-gnuplot.sh -t STATS1-totals STATS2-totals .. STATSN-totals
+
+This will produce a single plot (png file).
+
+Plots, expectedly, can be large so some fluctuations or small spikes
+can go unnoticed. To deal with that, `slabinfo-gnuplot.sh' has two
+options to 'zoom-in'/'zoom-out':
+ a) -s %d,%d  overwrites the default image width and heigh
+ b) -r %d,%d  specifies a range of samples to use (for example,
+              in `slabinfo -X >> FOO_STATS; sleep 1;' case, using
+              a "-r 40,60" range will plot only samples collected
+              between 40th and 60th seconds).

-
- (*) try_to_unmap_anon()
-
-     To unmap anonymous pages, each VMA in the list anchored in the anon_vma
-     must be visited - at least until a VM_LOCKED VMA is encountered.  If the
-     page is being unmapped for migration, VM_LOCKED VMAs do not stop the
-     process because mlocked pages are migratable.  However, for reclaim, if
-     the page is mapped into a VM_LOCKED VMA, the scan stops.
-
-     try_to_unmap_anon() attempts to acquire in read mode the mmap semaphore of
-     the mm_struct to which the VMA belongs.  If this is successful, it will
-     mlock the page via mlock_vma_page() - we wouldn't have gotten to
-     try_to_unmap_anon() if the page were already mlocked - and will return
-     SWAP_MLOCK, indicating that the page is unevictable.
-
-     If the mmap semaphore cannot be acquired, we are not sure whether the page
-     is really unevictable or not.  In this case, try_to_unmap_anon() will
-     return SWAP_AGAIN.
-
- (*) try_to_unmap_file() - linear mappings
-
-     Unmapping of a mapped file page works the same as for anonymous mappings,
-     except that the scan visits all VMAs that map the page's index/page offset
-     in the page's mapping's reverse map priority search tree.  It also visits
-     each VMA in the page's mapping's non-linear list, if the list is
-     non-empty.
-
-     As for anonymous pages, on encountering a VM_LOCKED VMA for a mapped file
-     page, try_to_unmap_file() will attempt to acquire the associated
-     mm_struct's mmap semaphore to mlock the page, returning SWAP_MLOCK if this
-     is successful, and SWAP_AGAIN, if not.
-
- (*) try_to_unmap_file() - non-linear mappings
-
-     If a page's mapping contains a non-empty non-linear mapping VMA list, then
-     try_to_un{map|lock}() must also visit each VMA in that list to determine
-     whether the page is mapped in a VM_LOCKED VMA.  Again, the scan must visit
-     all VMAs in the non-linear list to ensure that the pages is not/should not
-     be mlocked.
-
-     If a VM_LOCKED VMA is found in the list, the scan could terminate.
-     However, there is no easy way to determine whether the page is actually
-     mapped in a given VMA - either for unmapping or testing whether the
-     VM_LOCKED VMA actually pins the page.
-
-     try_to_unmap_file() handles non-linear mappings by scanning a certain
-     number of pages - a "cluster" - in each non-linear VMA associated with the
-     page's mapping, for each file mapped page that vmscan tries to unmap.  If
-     this happens to unmap the page we're trying to unmap, try_to_unmap() will
-     notice this on return (page_mapcount(page) will be 0) and return
-     SWAP_SUCCESS.  Otherwise, it will return SWAP_AGAIN, causing vmscan to
-     recirculate this page.  We take advantage of the cluster scan in
-     try_to_unmap_cluster() as follows:
-
-	For each non-linear VMA, try_to_unmap_cluster() attempts to acquire the
-	mmap semaphore of the associated mm_struct for read without blocking.
-
-	If this attempt is successful and the VMA is VM_LOCKED,
-	try_to_unmap_cluster() will retain the mmap semaphore for the scan;
-	otherwise it drops it here.
-
-	Then, for each page in the cluster, if we're holding the mmap semaphore
-	for a locked VMA, try_to_unmap_cluster() calls mlock_vma_page() to
-	mlock the page.  This call is a no-op if the page is already locked,
-	but will mlock any pages in the non-linear mapping that happen to be
-	unlocked.
-
-	If one of the pages so mlocked is the page passed in to try_to_unmap(),
-	try_to_unmap_cluster() will return SWAP_MLOCK, rather than the default
-	SWAP_AGAIN.  This will allow vmscan to cull the page, rather than
-	recirculating it on the inactive list.
-
-	Again, if try_to_unmap_cluster() cannot acquire the VMA's mmap sem, it
-	returns SWAP_AGAIN, indicating that the page is mapped by a VM_LOCKED
-	VMA, but couldn't be mlocked.
+functions handle anonymous and mapped file and KSM pages, as these types of

+In each case, whether rmap_walk_anon() or rmap_walk_file() or rmap_walk_ksm(),
+it will call try_to_unmap_one() for every VMA which might contain the page.
+
+When trying to reclaim, if try_to_unmap_one() finds the page in a VM_LOCKED
+VMA, it will then mlock the page via mlock_vma_page() instead of unmapping it,
+and return SWAP_MLOCK to indicate that the page is unevictable: and the scan
+stops there.
+
+mlock_vma_page() is called while holding the page table's lock (in addition

+munlock or munmap system calls, mm teardown (munlock_vma_pages_all), reclaim,

+ *
+ * kmap_atomic() can't sleep (calls pagefault_disable()), thus it provides
+ * shortlived ala "temporary mappings" which historically were implemented as
+ * fixmaps (compile time addr etc). Their book-keeping is done per cpu.
+ *
+ *	Both these facts combined (preemption disabled and per-cpu allocation)
+ *	means the total number of concurrent fixmaps will be limited to max

+ *
+ * - the kernel vaddr space from 0x7z to 0x8z (currently used by vmalloc/module)
+ *   is now shared between vmalloc and kmap (non overlapping though)
+ *
+ * - Both fixmap/pkmap use a dedicated page table each, hooked up to swapper PGD
+ *   This means each only has 1 PGDIR_SIZE worth of kvaddr mappings, which means
+ *   2M of kvaddr space for typical config (8K page and 11:8:13 traversal split)
+ *
+ * - fixmap anyhow needs a limited number of mappings. So 2M kvaddr == 256 PTE
+ *   slots across NR_CPUS would be more than sufficient (generic code defines
+ *   KM_TYPE_NR as 20).
+ *
+ * - pkmap being preemptible, in theory could do with more than 256 concurrent
+ *   mappings. However, generic pkmap code: map_new_virtual(), doesn't traverse
+ *   the PGD and only works with a single page table @pkmap_page_table, hence

- *
- * Params passed in registers:

- *  r1 = unlock SDRC DLL? (1 = yes, 0 = no).  Only unlock DLL for
- *      SDRC rates < 83MHz
- *  r2 = number of MPU cycles to wait for SDRC to stabilize after
- *      reprogramming the SDRC when switching to a slower MPU speed
- *  r3 = increasing SDRC rate? (1 = yes, 0 = no)
- *
- * Params passed via the stack. The needed params will be copied in SRAM
- *  before use by the code in SRAM (SDRAM is not accessible during SDRC
- *  reconfiguration):
- *  new SDRC_RFR_CTRL_0 register contents
- *  new SDRC_ACTIM_CTRL_A_0 register contents
- *  new SDRC_ACTIM_CTRL_B_0 register contents
- *  new SDRC_MR_0 register value
- *  new SDRC_RFR_CTRL_1 register contents
- *  new SDRC_ACTIM_CTRL_A_1 register contents
- *  new SDRC_ACTIM_CTRL_B_1 register contents
- *  new SDRC_MR_1 register value
- *
- * If the param SDRC_RFR_CTRL_1 is 0, the parameters are not programmed into
- * the SDRC CS1 registers
- *
- * NOTE: This code no longer attempts to program the SDRC AC timing and MR
- * registers.  This is because the code currently cannot ensure that all
- * L3 initiators (e.g., sDMA, IVA, DSS DISPC, etc.) are not accessing the
- * SDRAM when the registers are written.  If the registers are changed while
- * an initiator is accessing SDRAM, memory can be corrupted and/or the SDRC
- * may enter an unpredictable state.  In the future, the intent is to
- * re-enable this code in cases where we can ensure that no initiators are
- * touching the SDRAM.  Until that time, users who know that their use case
- * can satisfy the above requirement can enable the CONFIG_OMAP3_SDRC_AC_TIMING
- * option.
- *
- * Richard Woodruff notes that any changes to this code must be carefully
- * audited and tested to ensure that they don't cause a TLB miss while
- * the SDRAM is inaccessible.  Such a situation will crash the system
- * since it will cause the ARM MMU to attempt to walk the page tables.
- * These crashes may be intermittent.

+	  keeps in the memory allocator.  If you need to allocate very large
+	  blocks of physically contiguous memory, then you may need to
+	  increase this value.
+
+	  This config option is actually maximum order plus one. For example,
+	  a value of 11 means that the largest free memory block is 2^10 pages.
+
+	  We make sure that we can allocate upto a HugePage size for each configuration.
+	  Hence we have :
+		MAX_ORDER = (PMD_SHIFT - PAGE_SHIFT) + 1 => PAGE_SHIFT - 2
+
+	  However for 4K, we choose a higher default value, 11 as opposed to 10, giving us
+	  4M allocations matching the default size used by generic code.

-*!
-*! FILE NAME  : i2c.c
-*!
-*! DESCRIPTION: implements an interface for IIC/I2C, both directly from other
-*!              kernel modules (i2c_writereg/readreg) and from userspace using
-*!              ioctl()'s
-*!
-*! Nov 30 1998  Torbjorn Eliasson  Initial version.
-*!              Bjorn Wesen        Elinux kernel version.
-*! Jan 14 2000  Johan Adolfsson    Fixed PB shadow register stuff -
-*!                                 don't use PB_I2C if DS1302 uses same bits,
-*!                                 use PB.
-*| June 23 2003 Pieter Grimmerink  Added 'i2c_sendnack'. i2c_readreg now
-*|                                 generates nack on last received byte,
-*|                                 instead of ack.
-*|                                 i2c_getack changed data level while clock
-*|                                 was high, causing DS75 to see  a stop condition

- * processor could come with a 32-bit CM. Moreover, accesses on 64-bit CMs

+ * introducing 64 bit GCRs and all prior CM versions having 32 bit GCRs.
+ * However we may run a kernel built for MIPS32 on a system with 64 bit GCRs,

- * The caller puts arg2 in %ecx, which gets pushed. The kernel will use

- * (found in entry.S) requires that we clobber %ecx with the desired %esp.
- * User code might expect that %ecx is unclobbered though, as it would be
- * for returning via the iret instruction, so we must push and pop.
- *
- * The caller puts arg3 in %edx, which the sysexit instruction requires
- * for %eip. Thus, exactly as for arg2, we must push and pop.
- *
- * Arg6 is different. The caller puts arg6 in %ebp. Since the sysenter
- * instruction clobbers %esp, the user's %esp won't even survive entry
- * into the kernel. We store %esp in %ebp. Code in entry.S must fetch
- * arg6 from the stack.
- *
- * You can not use this vsyscall for the clone() syscall because the
- * three words on the parent stack do not get copied to the child.
