Subject: x86: unify CPU feature string names
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fa1408e4df53ec1e61f59c030b3488a1ef0c635d;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86: unify CPU feature string names

Move the CPU feature string names to a separate file (common to 32
and 64 bits); additionally, make <asm/cpufeature.h> includable by host
code in preparation for including the CPU feature strings in the boot
code.
