The drm/ttm module is using a modified on-stack copy of the
struct vm_area_struct to be able to set a page protection with customized
caching. Fix that by adding a vmf_insert_mixed_prot() function similar
to the existing vmf_insert_pfn_prot() for use with drm/ttm.
I'd like to merge this through a drm tree.
Changes since v1:
*) Formatting fixes in patch 1
*) Updated commit message of patch 2.
Changes since v2:
*) Moved vmf_insert_mixed_prot() export to patch 2 (Michal Hocko)
*) Documented under which conditions it's safe to use a page protection
different from struct vm_area_struct::vm_page_prot. (Michal Hocko)
Changes since v3:
*) More documentation regarding under which conditions it's safe to use a
page protection different from struct vm_area_struct::vm_page_prot. This
time also in core vm. (Michal Hocko)

Seems all concerns with this series have been addressed. Could I have an
ack to merge this through a DRM tree?
Thanks,
Thomas
