working with dentries given to it.

Fix up some ->d_inode accesses in the chelsio driver.
(1) FILE_DATA() should just be replaced with file_inode().
(2) set_debugfs_file_size() should be removed and debugfs_create_file_size()
should be used to create the file.

Pull more power management and ACPI updates from Rafael Wysocki:
"These are fixes mostly (intel_pstate, ACPI core, ACPI EC driver,
cpupower tool), a new CPU ID for the Intel RAPL driver and one
intel_pstate driver improvement that didn't make it to my previous
pull requests due to timing.
Specifics:
- Fix a build warning in the intel_pstate driver showing up in
non-SMP builds (Borislav Petkov)
- Change one of the intel_pstate's P-state selection parameters for
Baytrail and Cherrytrail CPUs to significantly improve performance
at the cost of a small increase in energy consumption (Kristen
Carlson Accardi)
- Fix a NULL pointer dereference in the ACPI EC driver due to an
unsafe list walk in the query handler removal routine (Chris
Bainbridge)
- Get rid of a false-positive lockdep warning in the ACPI container
hot-remove code (Rafael J Wysocki)
- Prevent the ACPI device enumeration code from creating device
objects of a wrong type in some cases (Rafael J Wysocki)
- Add Skylake processors support to the Intel RAPL power capping
driver (Brian Bian)
- Drop the stale MAINTAINERS entry for the ACPI dock driver that is
regarded as part of the ACPI core and maintained along with it now
(Chao Yu)
- Fix cpupower tool breakage caused by a library API change in libpci
3.3.0 (Lucas Stach)"

If the special PRP0001 device ID is present in the given device's list
of ACPI/PNP IDs and the device has a valid "compatible" property in
the _DSD, it should be enumerated using the default mechanism,
unless some scan handlers match the IDs preceding PRP0001 in the
device's list of ACPI/PNP IDs. In addition to that, no scan handlers
matching the IDs following PRP0001 in that list should be attached
to the device.
To make that happen, define a scan handler that will match PRP0001
and trigger the default enumeration for the matching devices if the
"compatible" property is present for them.
Since that requires the check for platform_id and device->handler
to be removed from acpi_default_enumeration(), move the fallback
invocation of acpi_default_enumeration() to acpi_bus_attach()
(after it's checked if there's a matching ACPI driver for the
device), which is a better place to call it, and do the platform_id
check in there too (device->handler is guaranteed to be unset at
the point where the function is looking for a matching ACPI driver).

acpi_scan_is_offline() may be called under the physical_node_lock
lock of the given device object's parent, so prevent lockdep from
complaining about that by annotating that instance with
SINGLE_DEPTH_NESTING.

libpci 3.3.0 introduced an additional member in the pci_filter struct
which needs to be initialized to -1 to get the same behavior as before
the API change. The libpci internal helpers got updated accordingly,
but as the cpupower pci helpers initialized the struct themselves the
behavior changed.
Use the libpci helper pci_filter_init() to fix this and guard against
similar breakages in the future.
This fixes probing of the AMD fam12h/14h cpuidle monitor on systems
with libpci >= 3.3.0.

drivers/cpufreq/intel_pstate.c:1187:26: warning: initialization from incompatible pointer type
struct cpuinfo_x86 *c = &boot_cpu_data;
when doing randconfig builds.
This is caused by the fact that when !CONFIG_SMP, asm/processor.h
defines cpu_info to boot_cpu_data and the local variable
struct cpu_defaults *cpu_info
overshadows it leading to this unfortunate assignment in the
preprocessed source:
struct cpu_defaults *boot_cpu_data;
struct cpuinfo_x86 *c = &boot_cpu_data;
Rename the local variable and use static_cpu_has_safe() which alleviates
the need for defining a local cpuinfo_x86 pointer.

SSSE3 implementation to base layer") changed the prototypes of the
core asm SHA-512 implementations so that they are compatible with
the prototype used by the base layer.
However, in one instance, the register that was used for passing the
input buffer was reused as a scratch register later on in the code,
and since the input buffer param changed places with the digest param
-which needs to be written back before the function returns- this
resulted in the scratch register to be dereferenced in a memory write
operation, causing a GPF.
Fix this by changing the scratch register to use the same register as
the input buffer param again.

commit a39f46df33c6 ("toshiba_acpi: Fix regression caused by backlight extra
check code") causes the backlight to no longer work on the Toshiba Z30,
reverting that commit fixes this but restores the original issue fixed
by that commit.
Looking at the toshiba_acpi backlight code for a fix for this I noticed that
the toshiba code is the only code under platform/x86 which unconditionally
registers a vendor acpi backlight interface, without checking for acpi_video
backlight support first.
This commit adds the necessary checks bringing toshiba_acpi in line with the
other drivers, and fixing the Z30 regression without needing to revert the
commit causing it.
Chances are that there will be some Toshiba models which have a non working
acpi-video implementation while the toshiba vendor backlight interface does
work, this commit adds an empty dmi_id table where such systems can be added,
this is identical to how other drivers handle such systems.

This patch adds the support for the configuration of the keyboard
backlight on supported Dell laptops.
With this patch it is possible to set:
* keyboard backlight level
* timeout after which the backlight will be automatically turned off
* input activity triggers (keyboard, touchpad, mouse) that enable the backlight
* ambient light settings
The settings are exposed via /sys/class/leds/dell::kbd_backlight/
The code is based on the newly released documentation by Dell in the
libsmbios project.

Bug 93911 reported a broken handling of the BT device, causing the
driver to get stuck in a loop enabling/disabling the device whenever
the device is deactivated by the kill switch as follows:
1. The user activated the kill switch, causing the system to generate
a 0x90 (status change) event and disabling the BT device.
2. The driver catches the event and re-enables the BT device.
3. The system detects the device being activated, but since the kill
switch is activated, disables the BT device (again) and generates
a 0x90 event (again).
4. Repeat from 2.
This patch adds an extra check to verify the status of the BT device,
returning silently if it is already activated.
Also, checks and returns appropriate error values while evaluating
the AUSB and BTPO methods.

Some Toshiba laptops with the "Special Functions" feature enabled
fail to properly enable such feature unless a specific value is
used to enable the hotkey events.
This patch adds a new function called "*_enable_special_functions",
that simply makes a call to the HCI_HOTKEY_EVENT call, but this time
we are using a different parameter to make the "Special Functions"
mode work as expected.

With the previous patch adding support to "Hotkey Event Type", we can
now use the type to distinguish which keymap to use.
This patch changes the toshiba_acpi_setup_keyboard function to make
use of the hotkey event type to choose the correct keymap without the
need to use the DMI matching list.

This patch adds support to query the "Hotkey Event Type" the system
supports.
There are two main event types (so far), 0x10 and 0x11, with the
first being all those laptops that have the old keyboard layout, and
the latter all those new laptops with the new keyboard layout.

In commit bff431e49ff531a343fbb2b4426e313000844f32 ("ACPI: WMI: Add
ACPI-WMI mapping driver") this mutex was added, but the rest of the
final commit never actually made use of it, resulting in:

A git grep shows no other instances/references to the wmi_data_lock.
Delete it, assuming that the mutex addition was just a leftover from
an earlier work in progress version of the change, since the original
dates from 2008.

As GMUX depends on IO for iGP to be enabled and active, lock the IO at
vgaarb level. This should prevent GPU driver for dGPU to disable IO for
iGP while it tries to own legacy VGA IO.
This fixes usage of backlight control combined with closed nvidia
driver on some Apple dual-GPU (intel/nvidia) systems.
On those systems loading nvidia driver disables intel IO decoding,
disabling the gmux backlight controls as a side effect.
Prior to commits moving boot_vga from (optional) efifb to less optional
vgaarb this mis-behavior could be avoided by using right kernel config
(efifb enabled but vgaarb disabled).
This patch explicitly does not try to trigger vgaarb changes in order
to avoid confusing already running graphics drivers. If IO has been
mis-configured by vgaarb gmux will thus fail to probe.
It is expected to load/probe gmux prior to graphics drivers.

This patch adds a few more events sent to TOSXXXX devices, some of
them are already identified, while some others simply print a message
informing the type of event received.
Also, a netlink event is generated so that userspace apps, daemons,
etc. act accordingly to these events.

This should be >= instead of > because otherwise we read one element
past the end of the hotkey_keycode_map[] array.
The hotkey_keycode_map[] array has TPACPI_HOTKEY_MAP_LEN elements.
