From: Michael Roth <redacted> Determining which CPUID leafs have significant ECX/index values is also needed by guest kernel code when doing SEV-SNP-validated CPUID lookups. Move this to common code to keep future updates in sync.

Just call it arch/x86/include/asm/cpuid.h
And if you feel bored, you can move the cpuid* primitives from
asm/processor.h to it, in another patch so that processor.h gets
slimmer.
Thx.
