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.
