Subject: x86: prepare consolidation of cpu/ related code usage
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3bc258ad87e5b0bbbca247b24ce8fac380c7d86b;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

x86: prepare consolidation of cpu/ related code usage

Move mce.c to mce_32.c to allow the later move of the x86_64 mce.c
from arch/x86/kernel/ to ...kernel/cpu/mcheck

No code change.
