From: David S. Miller Date: Wed, 21 Jul 2010 01:25:24 +0000 (-0700) Subject: Merge branch 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11fe883936980fe242869d671092a466cf1db3e3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Merge branch 'master' of /linux/kernel/git/davem/net-2.6 Conflicts: drivers/vhost/net.c net/bridge/br_device.c Fix merge conflict in drivers/vhost/net.c with guidance from Stephen Rothwell. Revert the effects of net-2.6 commit 573201f36fd9c7c6d5218cdcd9948cee700b277d since net-next-2.6 has fixes that make bridge netpoll work properly thus we don't need it disabled.
