From a296ce75e304dcf163a770e3dc6ca580b7a61d29 Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Fri, 31 May 2013 19:36:52 +0200 Subject: Move the MARK_GRAPHICS_MEM_WRCOMB to x86 architecture The MARK_GRAPHICS_MEM_WRCOMB was spreading like a cancer since it was defined in sandybridge. It is really more of an x86 thing however, and we now have three systems that can use it. I considered making this more general, since it technically can apply to PTE-based systems like ARM, and maybe we should. But the 'WRCOMB' moniker is usually closely tied to the x86.
