The TCP delayed ack parameters can be configured from user space
application which runs with non-root credentials and does not have
direct write access to /proc entries. This commit creates shadow
files under /sys/kernel/ipv4 which maps to /proc/sys/net/ipv4.

wcnss: Log debug registers when receives certain notification

If powering on a subsystem during restart fails, SSR framework will send
a "powerup failure" notification to the subsystem. Add support that
WCNSS platform driver will register to listen the notifications and if
receives "powerup failure" notification, it will log the debug registers.

wcnss: add API to check if wcnss is undergoing an SSR

Wlan driver should not read registers from wcnss or
try to communicate with the chip when it is undergoing
a subsystem-restart. Added an API with the wcnss platform
driver to check if ssr is in progress, this API will be
used by the wlan driver to protect register access and
other prohibited operations.

ARM: OMAP2+: INTC: Acknowledge stuck active interrupts

commit 698b48532539484b012fb7c4176b959d32a17d00 upstream.

When an interrupt has become active on the INTC it will stay active
until it is acked, even if masked or de-asserted. The
INTC_PENDING_IRQn registers are however updated and since these are
used by omap_intc_handle_irq to determine which interrupt to handle,
it will never see the active interrupt. This will result in a storm of
useless interrupts that is only stopped when another higher priority
interrupt is asserted.

Fix by sending the INTC an acknowledge if we find no interrupts to
handle.

OMAP3 doesn't contain "l3_init_clkdm" clock domain. Use the

ARM: 8027/1: fix do_div() bug in big-endian systems

commit 80bb3ef109ff40a7593d9481c17de9bbc4d7c0e2 upstream.

In big-endian systems, "%1" get the most significant part of the value, cause the instruction to get the wrong result.

When viewing ftrace record in big-endian ARM systems, we found that
the timestamp errors:

swapper-0   [001] 1325.970000:   0:120:R ==> [001]    16:120:R events/1
events/1-16 [001] 1325.970000:   16:120:S ==> [001]    0:120:R swapper
swapper-0   [000] 1325.1000000:  0:120:R   + [000]    15:120:R events/0
swapper-0   [000] 1325.1000000:  0:120:R ==> [000]    15:120:R events/0
swapper-0   [000] 1326.030000:   0:120:R   + [000]  1150:120:R sshd
swapper-0   [000] 1326.030000:   0:120:R ==> [000]  1150:120:R sshd

When viewed ftrace records, it will call the do_div(n, base) function, which achieved arch/arm/include/asm/div64.h in. When n = 10000000, base = 1000000, in do_div(n, base) will execute "umull %Q0, %R0, %1, %Q2".

commit 4f8e940095536bc002a81666a4107a581c84e9b9 upstream.

PCM pointer callbacks in ice1712 driver check the buffer size boundary
wrongly between bytes and frames.  This leads to PCM core warnings
like:

   ALSA pcm_lib.c:352 BUG: pcmC3D0c:0, pos = 5461, buffer size = 5461, period size = 2730

mfd: max8925: Fix possible NULL pointer dereference on i2c_new_dummy error

commit 96cf3dedc491d2f1f66cc26217f2b06b0c7b6797 upstream.

During probe the driver allocates dummy I2C devices for RTC and ADC
with i2c_new_dummy() but it does not check the return value of this
calls.

In case of error (i2c_new_device(): memory allocation failure or I2C
address cannot be used) this function returns NULL which is later used
by i2c_unregister_device().

If i2c_new_dummy() fails for RTC or ADC devices, fail also the probe
for main MFD driver.
