Linus,

   # HEAD: 8ae292c66dcb160b3e1e16b66c3076d5a2c63873 x86/lib: Address kernel-doc warnings

x86 assembly code improvements for v6.7 are:

- Micro-optimize the x86 bitops code
- Define target-specific {raw,this}_cpu_try_cmpxchg{64,128}() to improve code generation
- Define and use raw_cpu_try_cmpxchg() preempt_count_set()
- Do not clobber %rsi in percpu_{try_,}cmpxchg{64,128}_op
- Remove the unused __sw_hweight64() implementation on x86-32
- Misc fixes and cleanups

 Thanks,

	Ingo
