Linus Torvalds 5780e39edb 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
