From: "Luis R. Rodriguez" <[email protected]> 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.
