3.16.7-ckt9 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Al Viro <viro at ZenIV.linux.org.uk>
commit 1711fd9addf214823b993468567cab1f8254fc51 upstream.
POLL_OUT isn't what callers of ->poll() are expecting to see; it's
actually __SI_POLL | 2 and it's a siginfo code, not a poll bitmap
bit...
