Dave, Daniel,

A small fix for the long-standing ttm vm page protection hack.

I'm sending this a separate pull request since it is touching mm code and
similar to the vmwgfx coherent stuff, Linus might want this as a separate
pull request. If sent separate it'd be good if it could still spend some
time in linux-next.

The mm changes have been acked by Andrew for merging through drm.
The ttm changes have been OK'd by Christian for a direct pull.

The following changes since commit 71e7274066c646bb3d9da39d2f4db0a6404c0a2d:

  Merge tag 'drm-intel-next-2020-01-14' of git://anongit.freedesktop.org/drm/drm-intel into drm-next (2020-01-15 16:57:54 +1000)
