Subject: drm/i915: Don't allocate context pages as mappable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c69766f2b9fa612840a820b68f7a417cc64c102b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Don't allocate context pages as mappable

Only the hardware really access them, so no need to have cpu
gtt access available.

Split out from Chris vma-bind rework.

Note that this is only possible due to the split-up of the mappable
pin flag into PIN_GLOBAL and PIN_MAPPABLE.
