From 1423bed239415edd1562c25be8a7408858fdbb19 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 4 Mar 2013 21:16:19 +0100 Subject: [PATCH] x86, msr: Unify variable names Make sure all MSR-accessing primitives which split MSR values in two 32-bit parts have their variables called 'low' and 'high' for consistence with the rest of the code and for ease of staring.
