Due to:
1e61f78baf ("x86/cpufeature: Make sure DISABLED/REQUIRED macros are updated")
No changes to tools using those headers (tools/arch/x86/lib/mem{set,cpu}_64.S)
seems necessary.
Detected by the tools build header drift checker:

really early to actually display a visible error message before the

Some requirements that are not in CPUID yet are also in the
