Merge branch 'x86/cpu' into WIP.x86/core, to merge the NOP changes & resolve a semantic conflict

Conflict-merge this main commit in essence:

  a89dfde3: ("x86: Remove dynamic NOP selection")

With this upstream commit:

  b9082970

: ("bpf: Use NOP_ATOMIC5 instead of emit_nops(&prog, 5) for BPF_TRAMP_F_CALL_ORIG")

Semantic merge conflict:

  arch/x86/net/bpf_jit_comp.c

  - memcpy(prog, ideal_nops[NOP_ATOMIC5], X86_PATCH_SIZE);
  + memcpy(prog, x86_nops[5], X86_PATCH_SIZE);
