Hi Linus, please pull from:

...to receive the last of the known regression fixes and fallout from
the Xarray conversion of the filesystem-dax implementation. On the path
to debugging why the dax memory-failure injection test started failing
after the Xarray conversion a couple more fixes for the
dax_lock_mapping_entry(), now called dax_lock_page(), surfaced. Those
plus the bug that started the hunt are now addressed. These patches
have appeared in a -next release with no issues reported.
Note the touches to mm/memory-failure.c are just the conversion to the
new function signature for dax_lock_page().
