From c72dcf83ff8585c95739abffa3be7c87ca63d66b Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 13:31:27 +0100 Subject: [PATCH] x86: move load_cr3 to a common place. There are currently two definitions of load_cr3, that essentially do the same thing. This patch moves them all to processor.h.
