Followup to this patchset:

https://lore.kernel.org/linux-kernel/20250218-force-cpu-bug-v3-0-da3df43d1936@google.com/

Note that some of these changes were actually a part of that patchset
originally, but got lost as the v2 was merged, apparently due to
confusion stemming from Lore losing data.

      x86/cpu: Remove some macros about feature names
      x86/cpu: Warn louder about {set,clear}cpuid
