Merge branch 'x86/cpu' into WIP.x86/core, to merge the NOP changes & resolve a semantic conflict
Conflict-merge this main commit in essence:
a89dfde3dc3c: ("x86: Remove dynamic NOP selection")
With this upstream commit:
b90829704780: ("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);
