x86/mm/pkeys: Fix mismerge of protection keys CPUID bits
Kirill Shutemov pointed this out to me.
The tip tree currently has commit:
dfb4a70f2 [x86/cpufeature, x86/mm/pkeys: Add protection keys related CPUID definitions]
whioch added support for two new CPUID bits: X86_FEATURE_PKU and
X86_FEATURE_OSPKE. But, those bits were mis-merged and put in
cpufeature.h instead of cpufeatures.h.
This didn't cause any breakage *except* it keeps the "ospke" and
"pku" bits from showing up in cpuinfo.
Now cpuinfo has the two new flags:
flags : ... pku ospke
BTW, is it really wise to have cpufeature.h and cpufeatures.h?
It seems like they can only cause confusion and mahem with tab
completion.
