From: Thomas Hellstrom <thellstrom@vmware.com>

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.
