Merge tag 'x86-asm-2023-10-28' of git://git./linux/kernel/git/tip/tip

Pull x86 assembly code updates from Ingo Molnar:

 - 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
