From: "Luis R. Rodriguez" <mcg...@suse.com>
The crusade to replace mtrr_add() with architecture agnostic
arch_phys_wc_add() is complete, this will ensure write-combining
implementations (PAT on x86) is taken advantage instead of using
MTRR. With the crusade done now, hide direct MTRR access for
drivers.
