Subject[PATCH 4.6 08/31] ipmr/ip6mr: Initialize the last assert time of mfc entries.
Date
4.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tom Goff <thomas.goff@ll.mit.edu>

[ Upstream commit 70a0dec45174c976c64b4c8c1d0898581f759948 ]

This fixes wrong-interface signaling on 32-bit platforms for entries
created when jiffies > 2^31 + MFC_ASSERT_THRESH.
