Subject[PATCH 1/2] x86, microcode: Correct microcode revision format
Date
From: Borislav Petkov <borislav.petkov@amd.com>

506ed6b53e00ba303ad778122f08e1fca7cf5efb added microcode revision format
to /proc/cpuinfo and the MCE handler in decimal format but both AMD and
Intel patch levels are handled as hex numbers. Fix it.
