Subject: [PATCH 0/3] COVER: Remove memcpy_page_flushcache()

Commit 21b56c847753 ("iov_iter: get rid of separate bvec and xarray 
callbacks") removed the calls to memcpy_page_flushcache().

kmap_atomic() is deprecated and used in the x86 version of
memcpy_page_flushcache().

Remove the unnecessary memcpy_page_flushcache() call from all arch's.
