Oleksandr Andrushchenko c1e9cfc815 drm/xen-front: Fix mmap attributes for display buffers ... [ Upstream commit 24ded292a5c2ed476f01c77fee65f8320552cd27 ] When GEM backing storage is allocated those are normal pages, so there is no point using pgprot_writecombine while mmaping. This fixes mismatch of buffer pages' memory attributes between the frontend and backend which may cause screen artifacts.
