From 6a360048a1a4f8eaebbf9c4ec75fe4a9543421b2 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 13 Feb 2014 10:30:42 -0600 Subject: haswell: backup the default SMM region on resume Haswell CPUs need to use the default SMM region for relocating to the desired SMM location. Back up that memory on resume instead of reserving the default region. This makes the haswell support more forgiving to software which expects PC-compatible memory layouts.
