-gerrit commit 598b6a366801f2302402f567926d9c38a6f988f8 Author: Duncan Laurie <[email protected]> Date: Wed Oct 10 12:11:55 2012 -0700 SMM: Fix save state searching for GSMI The search for save state was comparing the entire RAX value when it needs to just operate on the bottom byte so it can find the GSMI command in bits 7:0 but not the extended command code in bits 15:8.
