A plain 64-bit division causes a link failure in some configurations:
ERROR: modpost: "__aeabi_uldivmod" [sound/soc/codecs/snd-soc-rt1320-sdw.ko] undefined!
Since this divides by a constant, using the div_u64() macro ends up
turning this into an efficient multiply/shift operation where possible.
In rt1320_calc_r0(), the open-coded shift seems a litle simpler.

It is better to check directly whether or not CONFIG_PM has
been enabled instead of relying on an error value returned by
pm_runtime_put() in that case because pm_runtime_put() may also return
an error value in other cases, like after writing "on" to the devices'
runtime PM "control" attribute in sysfs for one example.
This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

Some fixups to the jack handling, adding some necessary hooks to connect
things with the machine driver. I have split these out from the system
suspend chain as that has been generating a fair amount of discussion
and getting these 3 merged is far more important to get basic
functionality working smoothly. I will do a spin of the system suspend
stuff soon, if either no new comments pop up, or we reach some consensus
on how to proceed.
This loop iterates 200 times and then gives up. The problem is that
currently the loop exits with "retry" set to -1 on the failure path but
the check for failure expects it to be 0. Change from a post-op to a
pre-op so that it exits with "retry" set to 0.

Enhance the coccicheck script to filter *.cocci files based on the
specified MODE (e.g., report, patch). This ensures that only compatible
semantic patch files are executed, preventing errors such as:
"virtual rule report not supported"
This error occurs when a .cocci file does not define a 'virtual <MODE>'
rule, yet is executed in that mode.
For example:
make coccicheck M=drivers/hwtracing/coresight/ MODE=report
In this case, running "secs_to_jiffies.cocci" would trigger the error
because it lacks support for 'report' mode. With this change, such files
are skipped automatically, improving robustness and developer
experience.

clang is generating very inefficient code for native_save_fl() which is
used for local_irq_save() in critical spots.
Allowing the "pop %0" to use memory:
1) forces the compiler to add annoying stack canaries when
CONFIG_STACKPROTECTOR_STRONG=y in many places.
2) Almost always is followed by an immediate "move memory,register"
One good example is _raw_spin_lock_irqsave, with 8 extra instructions
ffffffff82067a30 <_raw_spin_lock_irqsave>:
ffffffff82067a30: ...
ffffffff82067a39: 53 push %rbx
// Three instructions to ajust the stack, read the per-cpu canary
// and copy it to 8(%rsp)
ffffffff82067a3a: 48 83 ec 10 sub $0x10,%rsp

ffffffff82067a46: 48 89 44 24 08 mov %rax,0x8(%rsp)
ffffffff82067a4b: 9c pushf
// instead of pop %rbx, compiler uses 2 instructions.
ffffffff82067a4c: 8f 04 24 pop (%rsp)
ffffffff82067a4f: 48 8b 1c 24 mov (%rsp),%rbx

Work around clang problems with "=rm" asm constraint.
clang seems to always chose the memory output, while it is almost

Add ASM_OUTPUT_RM so that we can replace "=rm" constraint
where it matters for clang, while not penalizing gcc.

other series:
- Simplify checks in arch_kfence_init_pool() since force_pte_mapping()
already takes BBML2-noabort (break-before-make Level 2 with no aborts
generated) into account
- Remove unneeded SVE/SME fallback preserve/store handling in the arm64
EFI. With the recent updates, the fallback path is only taken for EFI
runtime calls from hardirq or NMI contexts. In practice, this only
happens under panic/oops/emergency_restart() and no restoring of the
user state expected. There's a corresponding lkdtm update to trigger
a BUG() or panic() from hardirq context together with a fixup not to
confuse clang/objtool about the control flow
GCS (guarded control stacks) fix: flush the GCS locking state on exec,
otherwise the new task will not be able to enable GCS (locked as
