This patchset has a fixup for gup/mm, and provides the necessary arch
hooks to enable protected virtualization.

Andrew: please simply squash/fixup the first patch into the appropriate
one that is already in your tree.

v1 -> v2:
* use put_compound_head in the first patch
* fix commit message of the second patch
* minor code cleanups
* some comments to explain why sometimes we are not doing things
