From: Gavin Shan <shangw@linux.vnet.ibm.com> Date: Tue, 4 Mar 2014 15:35:20 +0800 > In kexec scenario, we failed to load the mlx4 driver in the > second kernel because the ownership bit was hold by the first > kernel without release correctly. > > The patch adds shutdown() interface so that the ownership can > be released correctly in the first kernel. It also helps avoiding > EEH error happened during boot stage of the second kernel because > of undesired traffic, which can't be handled by hardware during > that stage on Power platform. > > Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> > Tested-by: Wei Yang <weiyang@linux.vnet.ibm.com> Applied.
