#     Revert "drm/i915/userptr: Acquire the page lock around set_page_dirty()"
#     
#     The userptr put_pages can be called from inside try_to_unmap, and so
#     enters with the page lock held on one of the object's backing pages. We
#     cannot take the page lock ourselves for fear of recursion.
