So this is what I've pushed to my perf/core branch:

https://git.kernel.org/acme/c/707ba03243d2 (HEAD -> perf/core) Revert "x86/asm: Allow again using asm.h when building for the 'bpf' clang target"
https://git.kernel.org/acme/c/4364203f5563 pref tests bpf: Remove unused ptrace.h include from LLVM test

Thanks,
