To pick the changes from:

  d341db8f ("x86/cpufeatures: Add AMD Collaborative Processor Performance Control feature flag")

This only causes these perf files to be rebuilt:

  CC       /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
  CC       /tmp/build/perf/bench/mem-memset-x86-64-asm.o

And addresses this perf build warning:
