Subject: [PATCH 0/2] mm, drm/ttm: Fix pte insertion with customized protection
Date: Tue,  3 Dec 2019 08:54:44 +0100	[thread overview]
Message-ID: <20191203075446.60197-1-thomas_os@shipmail.org> (raw)

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.
