Pull MIPS fixes from Ralf Baechle:
"Another round of MIPS fixes for 4.2.
Things are looking quite decent at this stage but the recent work on
the FPU support took its toll:
- fix an incorrect overly restrictive ifdef
- select O32 64-bit FP support for O32 binary compatibility
- remove workarounds for Sibyte SB1250 Pass1 parts. There are rare
fixing the workarounds is not worth the effort.
- patch up an outdated and now incorrect comment"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: fpu.h: Allow 64-bit FPU on a 64-bit MIPS R6 CPU
MIPS: SB1: Remove support for Pass 1 parts.
MIPS: Require O32 FP64 support for MIPS64 with O32 compat
MIPS: asm-offset.c: Patch up various comments refering to the old filename.

Pass 1 parts had a number of significant erratas and were only available
in small numbers and under NDA. Full support also required the use of a
special toolchain that kept branches properly aligned. These workarounds
were never upstreamed and the only toolchain known to have them is
Montavista's GCC 3.0-based toolchain which completly obsoleted if not
useless these days.
So now that automated testing has tripped over the user of the
-msb1-pass1-workarounds option, rather than fixing it remove support for
pass 1 parts.
Probably nobody will notice. I seem to own the last know pass 1 board
and I haven't noticed another one in the wild in the past decade, at
least.

bcmgenet driver needs to separate packet drops from packet errors.
When the driver has to drop a *good* packet, due to lack of buffers or
replacement skbs, increment only dev->stats.[rx|tx]_dropped.
When the driver encounters a bad Rx packet or Tx error, increment only
dev->stats.[rx|tx]_errors + relevant detailed error counter.

Value returned by devm_ioremap_resource() was checked for non-NULL but
devm_ioremap_resource() returns IOMEM_ERR_PTR, not NULL. In case of
error this could lead to dereference of ERR_PTR.

In commit 'c03abd84634d ("net: ethernet: cpsw: don't requests
IRQs we don't use")', common isr is split into tx and rx, but
in rx isr tx interrupt is also disabledi in cpsw_disable_irq().
So tx interrupts are not handled during rx interrupts and rx
napi completion and results in poor tx performance by 40Mbps.
Fixing by disabling only rx interrupt in rx isr.

Use eth_hw_addr_random() instead of calling random_ether_addr().
Here, this change is setting addr_assign_type to NET_ADDR_RANDOM.
The Coccinelle semantic patch that performs this transformation
is as follows:
@@
identifier a,b;
@@
-random_ether_addr(a->b);
+eth_hw_addr_random(a);

The limit for BQL is updated each time we call
netdev_tx_completed_queue.
Without this patch the BQL limit was updated for every TX event we
see.
The issue was that this only updated the limit to handle the data
we complete in two events as the first event wouldn't show that
enough traffic had been processed between them.
This was OK when interrupt moderation was off but not when it was
on as more data had to be completed in a single interrupt.
The patch changes this so that we do report the completion to BQL
only when all the TX events in the interrupt have been processed.

As its first order of business, boomerang_interrupt() checks whether
the device really has any pending interrupts. If it does not,
it does nothing and returns, but it still returns IRQ_HANDLED.
This is wrong: interrupt was not handled, IRQ handlers of other
devices sharing this IRQ line need to be called.
vortex_interrupt() has it right: it returns IRQ_NONE in this case
via IRQ_RETVAL(0).
Do the same in boomerang_interrupt().

When cpsw's number of slave is set to 1 in device tree and while
accessing second slave ndev and priv in cpsw_tx_interrupt(),
there is a kernel crash. This is due to cpsw_get_slave_priv()
not verifying number of slaves while retriving netdev priv and
returns a invalid memory region. Fixing the issue by introducing
number of slave check in cpsw_get_slave_priv() and
cpsw_get_slave_ndev().

Some versions of MCFW do not support the MC_CMD_VADAPTOR_SET_MAC
command, and ENOSYS will be returned.
If the PF created its own vport, the function's datapath must be
stopped and the vport can be reconfigured to reflect the new MAC
address.
If the MCFW created the vport for the PF (which is the case when
the nic_data->vport_mac is blank), nothing further needs to be
done as the vport is not under the control of the PF.
This only applies to PFs because the MCFW in question does not
support VFs.

Re-organize the structure of error handling to avoid having
to duplicate the netif_err() around the ifdefs.
The only change to the behaviour of the error-handling is that
the PF's data structure to record VF details should only be
updated if the original command succeeded.

When a switch is attached to the mdio bus, the mdio bus can be used
while the interface is not open. If the IPG clock is not enabled, MDIO
reads/writes will simply time out.
Add support for runtime PM to control this clock. Enable/disable this
clock using runtime PM, with open()/close() and mdio read()/write()
function triggering runtime PM operations. Since PM is optional, the
IPG clock is enabled at probe and is no longer modified by
fec_enet_clk_enable(), thus if PM is not enabled in the kernel, it is
guaranteed the clock is running when MDIO operations are performed.

When running a kernel configured with CONFIG_DMA_API_DEBUG=y a warning
is issued:
DMA-API: device driver tries to sync DMA memory it has not allocated
This warning is the result of mapping the full range of the Rx buffer
pages allocated and then performing a dma_sync_single_for_cpu against
a calculated DMA address. The proper thing to do is to use the
dma_sync_single_range_for_cpu with a base DMA address and an offset.

Part of commit 49aa284fe64c4c1 ("cxgb4: Add support for devlog")
change introduced a real bug where the Device Log Sequence Numbers are
no longer being converted from firmware Big-Endian to local CPU-Endian
format.
This patch moves all of the translation into the devlog_show() routine.
The only endianness code now in devlog_open() is the small loop to find the
earliest (lowest Sequence Number) Device Log entry in the circular buffer.

In enic_poll, we clean tx and rx queues, when low latency busy socket polling
is happening, enic_poll will only clean tx queue. After cleaning tx, it should
return total budget for re-poll.
There is a small window between vnic_intr_unmask() and enic_poll_unlock_napi().
In this window if an irq occurs and napi is scheduled on different cpu, it tries
to acquire enic_poll_lock_napi() and fails. Unlock napi_poll before unmasking
the interrupt.
v2:
Do not change tx wonk done behaviour. Consider only rx work done for completing
napi.

When allocating Rx related buffers, alloc_pages is called using an order
number that is decreased until successful. A system under stress can
experience failures during this allocation process resulting in a warning
being issued. This message can be of concern to end users even though the
failure is not fatal. Since the failure is not fatal and can occur
multiple times, the driver should include the __GFP_NOWARN flag to
suppress the warning message from being issued.

All BCM7xxx integrated Gigabit PHYs have an issue in their MDIO
management controller which will make the initial read or write to them
to fail and return 0xffff. This is a real issue as the typical first
thing we do is read from MII_PHYSID1 and MII_PHYSID2 from get_phy_id()
to register a driver for these PHYs.
Coupled with the workaround in drivers/net/phy/bcm7xxx.c, this
workaround for the MDIO bus controller consists in scanning the list of
PHYs to do this initial read workaround for as part of the MDIO bus
reset routine which is invoked prior to mdiobus_scan().
Once we have a proper PHY driver/device registered, all workarounds are
located there (e.g: power management suspend/resume calls).

With CONFIG_DMA_API_DEBUG=y bnx2x triggers the error "DMA-API: device
driver frees DMA memory with wrong function".
On archs where PAGE_SIZE > SGE_PAGE_SIZE it also triggers "DMA-API:
device driver frees DMA memory with different size".
Fix this by making the mapping and unmapping symmetric:
- Do not map the whole pool page at once. Instead map the
SGE_PAGE_SIZE-sized pieces individually, so they can be unmapped in
the same manner.
- What's mapped using dma_map_page() must be unmapped using
dma_unmap_page().
Tested on ppc64.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2015-06-26
This series contains fixes for igb, e1000e and i40evf.
Todd disables IPv6 extension header processing due to a hardware errata
and bumps the driver version.
Yanir provides six fixes for e1000e. First is a fix for a locking issue
where we were not always taking the pci_bus_sem semaphore all the time
when calling pci_disable_link_state_locked(), so fix the code to only call
pci_disable_link_state_locked() when the semaphore has been acquired,
otherwise call pci_disable_link_state(). A previous fix for i219 where
the hardware prevented ULP entry caused EEE in Sx not the be enabled, so
modify the code flow that allows both ULP and EEE in Sx. Fix an issue
when running 10/100 full duplex on i219 where CRC errors were occurring
by increasing the IPG from 8 to 0xC as per the hardware developers.
Fix a data corruption issue found on some platforms by increasing the
minimum gap between the PHY FIFO read and write pointers. Fix i219,
which does not require the K1 workaround for LPT devices.
Mitch provides a i40evf fix for a panic when changing MTU. Down was
requesting queue disables, but then exited immediately without waiting
for the queues to actually be disabled. This could allow any function
called after i40evf_down() to run immediately, including i40evf_up(),
and causes a memory leak. Fixed the issue by removing the whole
reinit_locked function which allows for the driver to handle the state
changes by requesting reset from the periodic timer. The second fix
resolves an issue where RSS was being configured as though it is using
the maximum number of queue. This can cause the device to drop a lot
of receive traffic, as the packets get assigned to non-functional queues.
This is resolved by only configuring RSS with the number of active queues.

The driver will only configure as many queues as there are available
CPUs, up the maximum number of queues. However, it always configures
RSS as though it is using the maximum number of queues. This can cause
the device to drop a lot of RX traffic, as the packets get assigned to
nonfunctional queues.
Fix this by only configuring RSS with the number of active queues.

Down was requesting queue disables, but then exited immediately
without waiting for the queues to actually disable. This could
allow any function called after i40evf_down to run immediately,
including i40evf_up, and causes a memory leak.
Removing the whole reinit_locked function is the best way
to go about this, and allows for the driver to handle the
state changes by requesting reset from the periodic timer.
Also, add a couple WARN_ONs in slow path to help us recognize
if we re-introduce this issue or missed any cases.

pci_bus_sem to be held, but is also called from places where this semaphore
was not previously acquired. This patch implements two flavors of

As bnx2x_init_ptp() is only called if bp->flags contains PTP_SUPPORTED,
we also need to guard bnx2x_stop_ptp() with same condition, otherwise
ptp_task workqueue is not initialized and kernel barfs on
cancel_work_sync()

Not all silicon implementations of the Freescale FEC hardware module
have the RACC (Receive Accelerator Function) register, so we should not
be trying to access it on those that don't. Currently none of the ColdFire
based parts with a FEC have it.
Support for RACC was introduced by commit 4c09eed9 ("net: fec: Enable imx6
enet checksum acceleration"). A fix was introduced in commit d1391930
("net: fec: Fix build for MCF5272") that disables its use on the ColdFire
M5272 part, but it doesn't fix the general case of other ColdFire parts.
To fix we create a quirk flag, FEC_QUIRK_HAS_RACC, and check it before
working with the RACC register.

Due to FW constraints, driver must make sure that transmitted SKBs will
not be too fragmented, or in the case that they are - that each 'window'
of fragments passed to the FW would contain at least an mss worth of data.
For encapsultaed packets the calculation is wrong, since it ignores the
inner headers in the calculation of the headers' length.
This could lead to a FW assertion in case of a too-fragmented encapsulated
packet.

Since driver statistics flow access MACs and those might reset during
link re-configurations, when we're about to change link properties we
have to make sure that statistics are not operational.
Statisics would be re-enabled [i.e., gathering of statistics would
re-commence] once physical link is achieved again.
Since driver employs a link-flap avoidance scheme, there are scenarios
where driver will receive no indication that the new link is up, and
as a result the statistics would not be re-enabled.
Preventing LFA from working in such cases would guarantee that we'll
always receive such indications and thus will fix statistics gathering.

20g-capable devices are not configured properly for self-test, using
10g as their speed which cause the link indication to remain down and
fail the internal loopback test.

There's a bug in today's driver where VF requests to add/remove MAC filters
always reach the Hypervisor as add requests.
This prevents the VF from changing its MAC address, as it cannot remove the
previously configured MAC and runs out of MAC credits.
