Subject: ARM: Make CONFIG_CPU_V7 valid for 32bit ARMv8 implementations
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=252309adc81f529d42c8c90a4965866ec82cb6ad;p=linux.git

ARM: Make CONFIG_CPU_V7 valid for 32bit ARMv8 implementations

ARMv8 is a superset of ARMv7, and all the ARMv8 features are
discoverable with a set of ID registers. It means that we can
use CPU_V7 to guard ARMv8 features at compile time.

This commit simply amends the CPU_V7 configuration symbol comment
to reflect that CPU_V7 also covers ARMv8.
