From 9cd4d78e21cfdc709b1af516214ec4f69ee0e6bd Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Thu, 20 Dec 2012 23:44:22 -0800 Subject: x86/microcode_intel.h: Define functions and macros for early loading ucode Define some functions and macros that will be used in early loading ucode. Some of them are moved from microcode_intel.c driver in order to be called in early boot phase before module can be called.
