Subject: [PATCH] powerpc/powernv: Unfreeze VF PE on releasing it
Date: Tue, 23 Jun 2015 17:01:13 +1000	[thread overview]
Message-ID: <1435042873-9486-1-git-send-email-gwshan@linux.vnet.ibm.com> (raw)

When releasing PE for SRIOV VF, the PE is forced to be frozen
wrongly. When the same PE is picked for another VF, it won't
work anyhow. The patch fixes the issue by unfreezing, not
freezing the VF PE when releasing it.
