From: John Hubbard <jhubbard@nvidia.com>

For pages that were retained via get_user_pages*(), release those pages
via the new put_user_page*() routines, instead of via put_page() or

This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").

This is a merge-able version of the fix, because it restricts
itself to put_user_page() and put_user_pages(), both of which
have not changed their APIs. Later, i915_gem_userptr_put_pages()
can be simplified to use put_user_pages_dirty_lock().
