With this fix in place, all the VRAM mappings for GPU drivers ended up at UC instead of WC. There are probably better ways to fix this long term, but nothing I'd considered for -fixes that wouldn't need more settling in time. So I've just created a new arch API that the drivers can reserve all their VRAM aperture ranges as WC" * tag 'drm-x86-pat-regression-fix' of git://people.freedesktop.org/~airlied/linux: drm/drivers: add support for using the arch wc mapping API. x86/io: add interface to reserve io memtype for a resource range.
