Jane Chu 4a83a9deea mm/memory-failure: unnecessary amount of unmapping 
[ Upstream commit 4d75136be8bf3ae01b0bc3e725b2cdc921e103bd ]

It appears that unmap_mapping_range() actually takes a 'size' as its third
argument rather than a location, the current calling fashion causes
unnecessary amount of unmapping to occur.
