Subject: [patch 04/30] x86/microcode: Include vendor headers into microcode.h

From: Ashok Raj <ashok.raj@...el.com>

Currently vendor specific headers are included explicitly when used in common
code. Instead, include the vendor specific headers in microcode.h, and
include that in all usages. No functional change.
