It seems I forgot to add handling of devmap_hash type maps to the device
unregister hook for devmaps. This omission causes devices to not be
properly released, which causes hangs.
Fix this by adding the missing handler.

r0-r3 & r12 registers are saved & restored, before & after svc
respectively. Intention was to preserve those registers across thread to
handler mode switch.
On v7-M, hardware saves the register context upon exception in AAPCS
complaint way. Restoring r0-r3 & r12 is done from stack location where
hardware saves it, not from the location on stack where these registers
were saved.
To clarify, on stm32f429 discovery board:
1. before svc, sp - 0x90009ff8
2. r0-r3,r12 saved to 0x90009ff8 - 0x9000a00b
3. upon svc, h/w decrements sp by 32 & pushes registers onto stack
4. after svc, sp - 0x90009fd8
5. r0-r3,r12 restored from 0x90009fd8 - 0x90009feb
Above means r0-r3,r12 is not restored from the location where they are
saved, but since hardware pushes the registers onto stack, the registers
are restored correctly.
Note that during register saving to stack (step 2), it goes past
0x9000a000. And it seems, based on objdump, there are global symbols
residing there, and it perhaps can cause issues on a non-XIP Kernel
(on XIP, data section is setup later).
Based on the analysis above, manually saving registers onto stack is at
best no-op and at worst can cause data section corruption. Hence remove
storing of registers onto stack before svc.

It turns out that commit 01ccf903ed ("pwm: Let pwm_get_state() return
the last implemented state") causes backlight failures on a number of
boards. The reason is that some of the drivers do not write the full
state through to the hardware registers, which means that ->get_state()
subsequently does not return the correct state. Consumers which rely on
pwm_get_state() returning the current state will therefore get confused
and subsequently try to program a bad state.
Before this change can be made, existing drivers need to be more
carefully audited and fixed to behave as the framework expects. Until
then, keep the original behaviour of returning the software state that
was applied rather than reading the state back from hardware.

Commit 03c4749dd6 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux
GPIO translation") has made the cherryview gpio numbers sparse, to get
a 1:1 mapping between ACPI pin numbers and gpio numbers in Linux.
This has greatly simplified things, but the code setting the
irq_valid_mask was not updated for this, so the valid mask is still in
the old "compressed" numbering with the gaps in the pin numbers skipped,
which is wrong as irq_valid_mask needs to be expressed in gpio numbers.
This results in the following error on devices using pin 24 (0x0018) on
the north GPIO controller as an ACPI event source:
[ 0.422452] cherryview-pinctrl INT33FF:01: Failed to translate GPIO to IRQ
This has been reported (by email) to be happening on a Caterpillar CAT T20
tablet and I've reproduced this myself on a Medion Akoya e2215t 2-in-1.
This commit uses the pin number instead of the compressed index into
community->pins to clear the correct bits in irq_valid_mask for GPIOs
using GPEs for interrupts, fixing these errors and in case of the
Medion Akoya e2215t also fixing the LID switch not working.

If regular request queue gets full, currently we sleep for a bit and
retrying submission in submitter's context. This assumes submitter is not
holding any spin lock. But this assumption is not true for background
requests. For background requests, we are called with fc->bg_lock held.
This can lead to deadlock where one thread is trying submission with
fc->bg_lock held while request completion thread has called
fuse_request_end() which tries to acquire fc->bg_lock and gets blocked. As
request completion thread gets blocked, it does not make further progress
and that means queue does not get empty and submitter can't submit more
requests.
To solve this issue, retry submission with the help of a worker, instead of
retrying in submitter's context. We already do this for hiprio/forget
requests.

If virtqueue is full, we put forget requests on a list and these forgets
are dispatched later using a worker. As of now we don't count these forgets
in fsvq->in_flight variable. This means when queue is being drained, we
have to have special logic to first drain these pending requests and then
wait for fsvq->in_flight to go to zero.
By counting pending forgets in fsvq->in_flight, we can get rid of special
logic and just wait for in_flight to go to zero. Worker thread will kick
and drain all the forgets anyway, leading in_flight to zero.
I also need similar logic for normal request queue in next patch where I am
about to defer request submission in the worker context if queue is full.
This simplifies the code a bit.
Also add two helper functions to inc/dec in_flight. Decrement in_flight
helper will later used to call completion when in_flight reaches zero.

Submission context can hold some locks which end request code tries to hold
again and deadlock can occur. For example, fc->bg_lock. If a background
request is being submitted, it might hold fc->bg_lock and if we could not
submit request (because device went away) and tried to end request, then
deadlock happens. During testing, I also got a warning from deadlock
detection code.
So put requests on a list and end requests from a worker thread.
I got following warning from deadlock detector.

Nvidia proprietary driver doesn't support runtime power management, so
when a user only wants to use the integrated GPU, it's a common practice
to let dGPU not to bind any driver, and let its upstream port to be
runtime suspended. At the end of runtime suspension the port uses
platform power management to disable power through _OFF method of power
resource, which is listed by _PR3.
After commit b516ea586d ("PCI: Enable NVIDIA HDA controllers"), when
the dGPU comes with an HDA function, the HDA won't be suspended if the
dGPU is unbound, so the power resource can't be turned off by its
upstream port driver.
Commit 37a3a98ef6 ("ALSA: hda - Enable runtime PM only for
discrete GPU") only allows HDA to be runtime suspended once GPU is
bound, to keep APU's HDA working.
However, HDA on dGPU isn't that useful if dGPU is not bound to any
driver. So let's relax the runtime suspend requirement for dGPU's HDA
function, to disable the power source to save lots of power.

According to the PM8916 Hardware Register Description,
CDC_D_CDC_CONN_HPHR_DAC_CTL has only a single bit (RX_SEL)
to switch between RX1 (0) and RX2 (1). It is not possible to
disable it entirely to achieve the "ZERO" state.
However, at the moment the "RDAC2 MUX" mixer defines three possible
values ("ZERO", "RX2" and "RX1"). Setting the mixer to "ZERO"
actually configures it to RX1. Setting the mixer to "RX1" has
(seemingly) no effect.
Remove "ZERO" and replace it with "RX1" to fix this.

When consumer requests a pin, in order to be on the safest side,
we switch it first to GPIO mode followed by immediate transition
to the input state. Due to posted writes it's luckily to be a single
I/O transaction.
However, if firmware or boot loader already configures the pin
to the GPIO mode, user expects no glitches for the requested pin.
We may check if the pin is pre-configured and leave it as is
till the actual consumer toggles its state to avoid glitches.

the same data buffer for slave and master operations. It also means
that H/W command queue handling is unreliable because of the buffer
sharing issue. To fix this issue, it clears command queue if a
master command is queued in pending state to use S/W solution
instead of H/W command queue handling. Also, it refines restarting

The following commit from the v5.4 merge window:

... breaks auxiliary trace buffer tracking.
If I run command 'perf record -e rbd000' to record samples and saving
them in the **auxiliary** trace buffer then the value of 'locked_vm' becomes
negative after all trace buffers have been allocated and released:
During allocation the values increase:

The value of user->locked_vm increases to a limit then the memory
is tracked by pinned_vm.
During deallocation the size is subtracted from pinned_vm until
it hits a limit. Then a larger value is subtracted from locked_vm
leading to a large number (because of type unsigned):

[64.270628] perf_mmap_close mmap_user->locked_vm:0xfffffffffffffe04 pinned_vm:0x0
This value sticks for the user until system is rebooted, causing
follow-on system calls using locked_vm resource limit to fail.
Note: There is no issue using the normal trace buffer.
In fact the issue is in perf_mmap_close(). During allocation auxiliary
trace buffer memory is either traced as 'extra' and added to 'pinned_vm'
or trace as 'user_extra' and added to 'locked_vm'. This applies for
normal trace buffers and auxiliary trace buffer.
However in function perf_mmap_close() all auxiliary trace buffer is
subtraced from 'locked_vm' and never from 'pinned_vm'. This breaks the
ballance.

There are two issues, likely copy/paste:
1. Use cdns->pcm.num_in instead of stream_num_in for consistency with
the rest of the code. This was not detected earlier since platforms did
not have input-only PDIs.
2. use the correct offset for bi-dir PDM, based on IN and OUT
PDIs. Again this was not detected since PDM was not supported earlier.

All the drivers, which use the OPP framework control regulators, which
are already enabled. Typically those regulators are also system critical,
due to providing power to CPU core or system buses. It turned out that
there are cases, where calling regulator_enable() on such boot-enabled
regulator has side-effects and might change its initial voltage due to
performing initial voltage balancing without all restrictions from the
consumers. Until this issue becomes finally solved in regulator core,
avoid calling regulator_enable()/disable() from the OPP framework.
This reverts commit 7f93ff73f7.

cifs_setattr_nounix has two paths which miss free operations
for xid and fullpath.
Use goto cifs_setattr_exit like other paths to fix them.

According to MS-CIFS specification MID 0xFFFF should not be used by the
CIFS client, but we actually do. Besides, this has proven to cause races
leading to oops between SendReceive2/cifs_demultiplex_thread. On SMB1,
MID is a 2 byte value easy to reach in CurrentMid which may conflict with
an oplock break notification request coming from server
