* Fix a livelock in dax_layout_busy_page() present since v4.18. The
   lockup triggers when truncating an actively mapped huge page out of a
   mapping pinned for direct-I/O.
 
 * Fix mprotect() clobbers of _PAGE_DEVMAP. Broken since v4.5 mprotect()
   clears this flag that is needed to communicate the liveness of device
   pages to the get_user_pages() path.
