x86: When cleaning MTRRs, do not fold WP into UC The current MTRR code treats WP as a form of UC. This really isn't desirable behaviour, except possibly in the case of severe MTRR shortage. Disable this, to allow legitimate uses of WP to remain unmolested. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: H.
