c7f5d10549 net: Add eth_platform_get_mac_address() helper.
A repeating pattern in drivers has become to use OF node information
and, if not found, platform specific host information to extract the
ethernet address for a given device.

Currently this is done with a call to of_get_mac_address() and then
some ifdef'd stuff for SPARC.

Consolidate this into a portable routine, and provide the
arch_get_platform_mac_address() weak function hook for all
architectures to implement if they want.

03996f2064 storvsc: Tighten up the interrupt path
On the interrupt path, we repeatedly establish the pointer to the
storvsc_device. While the compiler does inline get_in_stor_device() (and
other static functions) in the call chain in the interrupt path, the
compiler is repeatedly inlining the call to get_in_stor_device() each
time it is invoked.  The return value of get_in_stor_device() can be
cached in the interrupt path since there is higher level serialization
in place to ensure correct handling when the module unload races with
the processing of an incoming message from the host.  Optimize this code
path by caching the pointer to storvsc_device and passing it as an
argument.

c406700cdf ethernet/atheros/alx: sanitize buffer sizing and padding
This is based on the work done by Przemek Rudy in bug 70761 at
bugzilla.kernel.org, but with some work done to disentagle and clarify
things a bit.

Similar to Przemek's work and other drivers, we're adding a padding of 16
here, but we're also disentangling mtu size calculations from max buffer
size calculations a bit, and adding ETH_HLEN to the value written into
ALX_MTU. Hopefully, with a bit more consistency and clarity, things behave
better here. Sadly, I can only test in my alx-driven E2200, which worked
just fine before this patch.

In comment #58 of bug 70761, Eugene A. Shatokhin reports that this patch
does help considerably for a ROSA Linux user of his with an AR8162 network
adapter when patched into a 4.1.x-based kernel, with several days of
normal operation where wired network previously wasn't usable without
setting MTU to 9000 as a work-around.

Data is read in blocks of up to one fragment is size from the circular
buffer on the DSP and is re-packed to remove the padding byte that

565ace4641 ASoC: wm_adsp: Add a handler for the compressed IRQ
Here support is added for responding to DSP IRQs that are used to
indicate data being available on the DSP. The idea is that we check the
amount of data available upon receipt of an IRQ and on subsequent calls
to the pointer callback we recheck once less than one fragment is
available (to avoid excessive SPI traffic), if there is truely less than
one fragment available we ack the last IRQ and wait for a new one.

24338722cf ASoC: wm5110: Fix PGA clear when disabling DRE
We don't want to use a bypassed write in wm5110_clear_pga_volume,
we might disable the DRE whilst the CODEC is powered down. A
normal regmap_write will always go to the hardware (when not on
cache_only) even if the written value matches the cache. As using
a normal write will still achieve the desired behaviour of bring
the cache and hardware in sync, this patch updates the function
to use a normal write, which avoids issues when the CODEC is
powered down.

13331a551a SUNRPC: Fixup socket wait for memory
We're seeing hangs in the NFS client code, with loops of the form:

Turns out commit ceb5d58b21 ("net: fix sock_wake_async() rcu protection")
moved SOCKWQ_ASYNC_NOSPACE out of sock->flags and into sk->sk_wq->flags,
however it never tried to fix up the code in net/sunrpc.

The new idiom is to use the flags in the RCU protected struct socket_wq.
While we're at it, clear out the now redundant places where we set/clear
SOCKWQ_ASYNC_NOSPACE and SOCK_NOSPACE. In principle, sk_stream_wait_memory()
is supposed to set these for us, so we only need to clear them in the
particular case of our ->write_space() callback.

e7b11dc7b7 ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruption
Commit 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")
unified the GPMC debug for the SoCs with GPMC. The commit also left out
the option for HWMOD_INIT_NO_RESET as we now require proper timings for
GPMC to be able to remap GPMC devices out of address 0.

Unfortunately on Nokia N900, onenand now only partially works with the
device tree provided timings. It works enough to get detected but the
clock rate supported by the onenand chip gets misdetected. This in turn
causes the GPMC timings to be miscalculated and this leads into file
system corruption on N900.

Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync
write. This is needed also for async timings when we write to onenand
with omap2_onenand_set_async_mode(). Without sync write bit set, the
async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff.

Let's exit with an error if onenand rate is not detected. And let's
remove the extra call to omap2_onenand_set_async_mode() as we only need
to do this once at the end of omap2_onenand_setup_async().

Fixes: 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")

2a803c4db6 arm64: head.S: use memset to clear BSS
Currently we use an open-coded memzero to clear the BSS. As it is a
trivial implementation, it is sub-optimal.

Our optimised memset doesn't use the stack, is position-independent, and
for the memzero case can use of DC ZVA to clear large blocks
efficiently. In __mmap_switched the MMU is on and there are no live
caller-saved registers, so we can safely call an uninstrumented memset.

This patch changes __mmap_switched to use memset when clearing the BSS.
We use the __pi_memset alias so as to avoid any instrumentation in all
kernel configurations.
