 "This became a slightly big update, but it's more or less expected, as
  the first batch after holidays.

  All changes (but for the last two last-minute fixes) have been stewed
  in linux-next long enough, so it's fairly safe to take:

   - PCM UAF fix in 32bit compat layer

   - ASoC board-specific fixes for Intel, AMD, Medathek, Qualcomm

   - SOF power management fixes

   - ASoC Intel link failure fixes

   - A series of fixes for USB-audio regressions

   - CS35L41 HD-audio codec regression fixes

   - HD-audio device-specific fixes / quirks

  Note that one SPI patch has been taken in ASoC subtree mistakenly, and
  the same fix is found in spi tree, but it should be OK to apply"

Takes rwsem lock inside snd_ctl_elem_read instead of snd_ctl_elem_read_user
like it was done for write in commit 1fa4445f ("ALSA: control - introduce
snd_ctl_notify_one() helper"). Doing this way we are also fixing the following
locking issue happening in the compat path which can be easily triggered and
turned into an use-after-free.

64-bits:
snd_ctl_ioctl
  snd_ctl_elem_read_user
    [takes controls_rwsem]
    snd_ctl_elem_read [lock properly held, all good]
    [drops controls_rwsem]

32-bits:
snd_ctl_ioctl_compat
  snd_ctl_elem_write_read_compat
    ctl_elem_write_read
      snd_ctl_elem_read [missing lock, not good]

CVE-2023-0266 was assigned for this issue.

Recently AMT mode was enabled (somewhat unexpectedly) on the Lenovo
Z13 platform. The FW is advertising it is available and the driver tries
to use it - unfortunately it reports the profile mode incorrectly.

Note, there is also some extra work needed to enable the dynamic aspect
of AMT support that I will be following up with; but more testing is
needed first. This patch just fixes things so the profiles are reported
correctly.

- Remove vcca-supply and vdds-supply as mandatory for 14nm PHY and
  10nm PHY DT schemas respectively as they are not present on some
  SOCs using these PHYs
- Add the dsi-phy-regulator-ldo-mode to dsi-phy-28nm.yaml as it was
  missed out during txt to yaml migration
- Remove operating-points-v2 and power-domain as a required property
  for the DSI controller as thats not the case for every SOC
- Fix the description from display escape clock to display core
  clock in the dsi controller yaml
- Fix the memory leak for mdp1-mem path for the cases when we return

Pull s390 fixes from Heiko Carstens:

 - Add various missing READ_ONCE() to cmpxchg() loops prevent the
   compiler from potentially generating incorrect code. This includes a
   rather large change to the s390 specific hardware sampling code and
   its current use of cmpxchg_double().

   Do the fix now to get it out of the way of Peter Zijlstra's
   cmpxchg128() work, and have something that can be backported. The
   added new code includes a private 128 bit cmpxchg variant which will
   be removed again after Peter's rework is available. Also note that
   this 128 bit cmpxchg variant is used to implement 128 bit
   READ_ONCE(), while strictly speaking it wouldn't be necessary, and
   _READ_ONCE() should also be sufficient; even though it isn't obvious
   for all converted locations that this is the case. Therefore use this
   implementation for for the sake of clarity and consistency for now.

 - Fix ipl report address handling to avoid kdump failures/hangs.

 - Fix misuse of #(el)if in kernel decompressor.

 - Define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36,
   caused by the recently changed discard behaviour.

 - Make sure _edata and _end symbols are always page aligned.

 - The current header guard DEBUG_H in one of the s390 specific header
   files is too generic and conflicts with the ath9k wireless driver.

Pull nolibc fixes from Paul McKenney:

 - The fd_set structure was incorrectly defined as arrays of u32 instead
   of long, which breaks BE64. Fix courtesy of Sven Schnelle.

 - S_ISxxx macros were incorrectly testing the bits after applying them
   instead of bitwise ANDing S_FMT with the value. Fix from Warner Losh.

 - The mips code was randomly broken due to an unprotected "noreorder"
   directive in the _start code that could prevent the assembler from
   filling delayed slots. This in turn resulted in random other
   instructions being placed into those slots. Fix courtesy of Willy
   Tarreau.

 - The current nolibc header layout refrains from including files that
   are not explicitly included by the code using nolibc. Unfortunately,
   this causes build failures when such files contain definitions that
   are used (for example) by libgcc. Example definitions include raise()
   and memset(), which are called by some architectures, but only at
   certain optimization levels. Fix courtesy of Willy Tarreau.

 - gcc 11.3 in ARM thumb2 mode at -O2 recognized a memset() construction
   inside the memset() definition. The compiler replaced this
   construction with a call to... memset(). Userland cannot be forced to
   build with -ffreestanding, so an empty asm() statement was introduced
   into the loop the loop in order to prevent the compiler from making
   this unproductive transformation. Fix courtesy of Willy Tarreau.

 - Most of the O_* macros were wrong on RISCV because their octal values
   were coded as hexadecimal. This resulted in the getdents64() selftest
   failing. Fix courtesy of Willy Tarreau.

This was tested on x86_64, i386, armv5, armv7, thumb1, thumb2, mips and
riscv, all at -O0, -Os and -O3.

acpi_get_and_request_gpiod() does not take a gpio_lookup_flags argument
specifying that the pins direction should be initialized to a specific
value.

This means that in some cases the pins might be left in input mode, causing
the gpiod_set() calls made to enable the clk / regulator to not work.

One example of this problem is the clk-enable GPIO for the ov01a1s sensor
on a Dell Latitude 9420 being left in input mode causing the clk to
never get enabled.

Explicitly set the direction of the pins to output to fix this.

Unlike keys where userspace only reacts to keypresses, userspace may act
on switches in both (0 and 1) of their positions.

For example if a SW_TABLET_MODE switch is registered then GNOME will not
automatically show the onscreen keyboard when a text field gets focus on
touchscreen devices when SW_TABLET_MODE reports 0 and when SW_TABLET_MODE
reports 1 libinput will block (filter out) builtin keyboard and touchpad
events.

So to avoid unwanted side-effects EV_SW type inputs should only be
registered if they are actually present, only register SW_CAMERA_LENS_COVER
if it is actually there.

Use KE_VSW instead of KE_SW for the SW_CAMERA_LENS_COVER key_entry
and get the value of the switch from the status field when handling
SW_CAMERA_LENS_COVER events, instead of always reporting 0.

Also correctly set the initial SW_CAMERA_LENS_COVER value.

It is possible that we (the host/kernel driver) receive command messages
that are not intended for us. Ignore those for now.

The whole story is a bit more complicated: It is possible to enable
debug output on SAM, which is sent via SSH command messages. By default
this output is sent to a debug connector, with its own target ID
(TID=0x03). It is possible to override the target of the debug output
and set it to the host/kernel driver. This, however, does not change the
original target ID of the message. Meaning, we receive messages with
TID=0x03 (debug) but expect to only receive messages with TID=0x00
(host).

The problem is that the different target ID also comes with a different
scope of request IDs. In particular, these do not follow the standard
event rules (i.e. do not fall into a set of small reserved values).
Therefore, current message handling interprets them as responses to
pending requests and tries to match them up via the request ID. However,
these debug output messages are not in fact responses, and therefore
this will at best fail to find the request and at worst pass on the
wrong data as response for a request.

Therefore ignore any command messages not intended for us (host) for
now. We can implement support for the debug messages once we have a
better understanding of them.

Note that this may also provide a bit more stability and avoid some
driver confusion in case any other targets want to talk to us in the
future, since we don't yet know what to do with those as well. A warning
for the dropped messages should suffice for now and also give us a
chance of discovering new targets if they come along without any
potential for bugs/instabilities.

We are observing performance drop in many usecases which include
games, 3D benchmark applications,etc.. To solve this problem, We
are strictly not allowing top down flag enabled allocations to
steal the memory space from cpu visible region.

The idea is, we are sorting each order list entries in
ascending order and compare the last entry of each order
list in the freelist and return the max block.

This patch improves the 3D benchmark scores and solves
fragmentation issues.
