Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs into master
Pull xtensa csum regression fix from Al Viro:
"Max Filippov caught a breakage introduced in xtensa this cycle
by the csum_and_copy_..._user() series.
Cut'n'paste from the wrong source - the check that belongs
in csum_and_copy_to_user() ended up both there and in
csum_and_copy_from_user()"
