[PATCH 1/3] x86, cpufeatures: update cpufeaure macros

From: Dave Hansen
Date: Wed Jun 29 2016 - 16:01:12 EST



From: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx>

We had a new CPUID "NCAPINT" word added, but the REQUIRED_MASK and
DISABLED_MASK macros did not get updated. Update them.

None of the features was needed in these masks, so there was no
harm, but we should keep them updated anyway.
