powerpc/eeh: Remove EEH_PE_PHB_DEAD
The PE state (for eeh_pe instance) EEH_PE_PHB_DEAD is duplicate to EEH_PE_ISOLATED. Originally, those PHBs (PHB PE) with EEH_PE_PHB_DEAD would be removed from the system. However, it's safe to replace that with EEH_PE_ISOLATED. The patch also clear EEH_PE_RECOVERING after fenced PHB has been handled, either failure or success. It makes the PHB PE state consistent with: PHB functions normally NONE PHB has been removed EEH_PE_ISOLATED PHB fenced, recovery in progress EEH_PE_ISOLATED | RECOVERING Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
