Before downloading firmware, a command response is required to
identify the silicon. However, when downloading IVSC firmware,
reading data from the SPI transfers with the IVSC ROM is not
necessary. Therefore, the rx buffer of SPI transfer command is
determined based on the specific request of the caller.

Audio PD daemon will allocate memory for audio PD dynamic loading
usage when it is attaching for the first time to audio PD. As
part of this, the memory ownership is moved to the VM where
audio PD can use it. In case daemon process is killed without any
impact to DSP audio PD, the daemon process will retry to attach to
audio PD and in this case memory won't be reallocated. If the invoke
fails due to any reason, as part of err_invoke, the memory ownership
is getting reassigned to HLOS even when the memory was not allocated.
At this time the audio PD might still be using the memory and an

The DSP capability request call expects 2 arguments. First is the
information about the total number of attributes to be copied from
DSP and second is the information about the buffer where the DSP
needs to copy the information. The current design is passing the
information about the size to be copied from DSP which would be
considered as a bad argument to the call by DSP causing a failure
suggesting the same. The second argument carries the information
about the buffer where the DSP needs to copy the capability
information and the size to be copied. As the first entry of
capability attribute is getting skipped, same should also be
considered while sending the information to DSP. Add changes to
pass proper arguments to DSP.

The kernel test robot reported that clang no longer compiles the 32-bit
x86 kernel in some configurations due to commit 95ece48165
("locking/atomic/x86: Rewrite x86_32 arch_atomic64_{,fetch}_{and,or,xor}()
functions").
The build fails with
arch/x86/include/asm/cmpxchg_32.h:149:9: error: inline assembly requires more registers than available
and the reason seems to be that not only does the cmpxchg8b instruction
need four fixed registers (EDX:EAX and ECX:EBX), with the emulation
fallback the inline asm also wants a fifth fixed register for the
address (it uses %esi for that, but that's just a software convention
with cmpxchg8b_emu).
Avoiding using another pointer input to the asm (and just forcing it to
use the "0(%esi)" addressing that we end up requiring for the sw
fallback) seems to fix the issue.

late in the release cycle

The 'profile_pc()' function is used for timer-based profiling, which
isn't really all that relevant any more to begin with, but it also ends
up making assumptions based on the stack layout that aren't necessarily
valid.
Basically, the code tries to account the time spent in spinlocks to the
caller rather than the spinlock, and while I support that as a concept,
it's not worth the code complexity or the KASAN warnings when no serious
profiling is done using timers anyway these days.
And the code really does depend on stack layout that is only true in the
simplest of cases. We've lost the comment at some point (I think when
the 32-bit and 64-bit code was unified), but it used to say:
Assume the lock function has either no stack frame or a copy
of eflags from PUSHF.
which explains why it just blindly loads a word or two straight off the
stack pointer and then takes a minimal look at the values to just check
if they might be eflags or the return pc:
Eflags always has bits 22 and up cleared unlike kernel addresses
but that basic stack layout assumption assumes that there isn't any lock
debugging etc going on that would complicate the code and cause a stack
frame.
It causes KASAN unhappiness reported for years by syzkaller [1] and
others [2].
With no real practical reason for this any more, just remove the code.
Just for historical interest, here's some background commits relating to
this code from 2006:
0cb91a2293 ("i386: Account spinlocks to the caller during profiling for !FP kernels")
31679f38d8 ("Simplify profile_pc on x86-64")
and a code unification from 2009:
ef4512882d ("x86: time_32/64.c unify profile_pc")
but the basics of this thing actually goes back to before the git tree.

When clearing registers on new write requests was added, the protection
for currently running commands was missed leading to concurrent access
to the testunit registers. Check the flag beforehand.

STOP fallsthrough to WRITE_REQUESTED but this became problematic when
clearing the testunit registers was added to the latter. Actually, there
is no reason to clear the testunit state after STOP. Doing it when a new
WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.

Revert "nfsd: fix oops when reading pool_stats before server is started"
nfsd: initialise nfsd_info.mutex early.
simple stuff:
- null ptr/err ptr deref fixes
- fix for getting wedged on shutdown after journal error
- fix missing recalc_capacity() call, capacity now changes correctly
after a device goes read only
however: our capacity calculation still doesn't take into account when
we have mixed ro/rw devices and the ro devices have data on them,
that's going to be a more involved fix to separate accounting for
"capacity used on ro devices" and "capacity used on rw devices"
- boring syzbot stuff
slightly more involved:
- discard, invalidate workers are now per device
this has the effect of simplifying how we take device refs in these
paths, and the device ref cleanup fixes a longstanding race between
the device removal path and the discard path
- fixes for how the debugfs code takes refs on btree_trans objects
we have debugfs code that prints in use btree_trans objects. It uses
closure_get() on trans->ref, which is mainly for the cycle detector,
but the debugfs code was using it on a closure that may have hit 0,
which is not allowed; for performance reasons we cannot avoid having
not-in-use transactions on the global list.
introduce some new primitives to fix this and make the synchronization
here a whole lot saner
