commit a7a7aeefbc upstream.
When interrupting an application which was allocating DMAable
memory, it was possible, that the DMA memory was deallocated
twice, leading to the error symptoms below.
Thanks to Gerald, who analyzed the problem and provided this
patch.
I agree with his analysis of the problem: ddcb_cmd_fixups() ->
genwqe_alloc_sync_sgl() (fails in f/lpage, but sgl->sgl != NULL
and f/lpage maybe also != NULL) -> ddcb_cmd_cleanup() ->
genwqe_free_sync_sgl() (double free, because sgl->sgl != NULL and
f/lpage maybe also != NULL)
In this scenario we would have exactly the kind of double free that
would explain the WARNING / Bad page state, and as expected it is
caused by broken error handling (cleanup).
Using the Ubuntu git source, tag Ubuntu-4.4.0-33.52, he was able to reproduce
the "Bad page state" issue, and with the patch on top he could not reproduce
it any more.

commit 43605e293e upstream.
SEC registers are not accessible when the TXE device is in low power
state, hence the SEC interrupt cannot be processed if device is not
awake.
In some rare cases entrance to low power state (aliveness off) and input
ready bits can be signaled at the same time, resulting in communication
stall as input ready won't be signaled again after waking up. To resolve
this IPC_HHIER_SEC bit in HHISR_REG should not be cleaned if the
interrupt is not processed.

commit f862b6b24f upstream.
There is a possible integer overflow following by a buffer overflow
when accumulating messages coming from the FW to compose a full payload.
Occurrence of wrap around has to be prevented for next message size
calculation.
For unsigned integer the addition overflow has occurred when the
result is smaller than one of the arguments.
To simplify the fix, the types of buf.size and buf_idx are set to the
same width, namely size_t also to be aligned with the type of length
parameter in file read/write ops.

commit cf35d6e047 upstream.
`genwqe_user_vmap()` calls `get_user_pages_fast()` and if the return
value is less than the number of pages requested, it frees the pages and
returns an error (`-EFAULT`). However, it fails to consider a negative
error return value from `get_user_pages_fast()`. In that case, the test
`if (rc < m->nr_pages)` will be false (due to promotion of `rc` to a
large `unsigned int`) and the code will continue on to call
`genwqe_map_pages()` with an invalid list of page pointers. Fix it by
bailing out if `get_user_pages_fast()` returns a negative error value.

- drivers/misc fix for Kconfig PWM symbol

- fix at91sam9261/at91sam9261ek mistake in slow crystal vs. slow RC osc
* tag 'at91-fixes' of git://github.com/at91linux/linux-at91:
ARM: at91/dt: sam9261: remove slow RC osc
ARM: at91/dt: define sam9261ek slow crystal frequency

ARM: at91/dt: sam9n12: correct PLLA ICPLL and OUT values
ARM: at91/dt: sam9x5: correct PLLA ICPLL and OUT values
misc: atmel_pwm: fix Kconfig symbols
AT91 symbols AT91SAM9263, AT91SAM9RL, and AT91SAM9G45 do not exist and this
patch changes them to their correct ARCH_* version.
These symbols are chosen instead of the SOC_* ones because this driver is not
converted to DT.
Anyway, the ATMEL_PWM symbol and the associated driver will be removed soon,
during the move to the PWM sub-system.

There is architecture code in mach-at91 that depends on the
CONFIG_ATMEL_PWM symbol in order to call the soc-specific
at91_add_device_pwm function. While all of this is about code
that will be removed in the future, using DT probing and
the PWM framework, we currently get a build failure:
arch/arm/mach-at91/built-in.o: In function `at91_pwm_leds':
arch/arm/mach-at91/leds.c:88: undefined reference to `at91_add_device_pwm'

This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:
* LEDs code has been completely removed and replaced with
"gpio-leds" nodes in the tree (referencing dedicated
GPIO subnodes in sysreg - bindings documentation updated);
this also better fits the reality as some variants of the
motherboard don't have all the LEDs populated
* syscfg bridge code has been extracted into a separate
driver (placed in drivers/misc for no better place)
* all the ID & MISC registers are defined as sysconf
making them available for other drivers should they need
to use them (and also to the user via /sys/kernel/debug/regmap
which can be helpful in platform debugging)

Adding power gating introduced new waiting state for client also during
connection attempt, a connection request can be queued for later either due
device is power gated or due to other on going connection.
We setting client connection state before start of full connect procedure so
in both cased the client state will be MEI_FILE_CONNECTING
which create interlock between the two connection attempts, both
detecting that another connection is in progress.
The interlock is resolved by moving client to connecting state
only upon connection request transmission, so the first
cb in queue can be processed.
