Description: mm/mempolicy.c: fix error handling in set_mempolicy and mbind
References:
https://grsecurity.net/the_infoleak_that_mostly_wasnt.php
Notes:
bwh> As Brad Spengler notes, this doesn't affect amd64. The compat
bwh> wrappers are only used for swapping bitmap words on 64-bit
bwh> architectures that are (or can be) big-endian. Fixing this on
bwh> wheezy was a (small) waste of time.
