Subject: drm/i915: Use complete address space in true PPGTT
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a4e0bedca678c81eea4cd79a4bd502335639f73a;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: Use complete address space in true PPGTT

True PPGTT is capable of having a full address space, even if the system
has less allocated memory.

Note that aliasing PPGTT always aliases the GGTT and thus should remain
of the same size.
