[PATCH] ppc64: serialize reports of PCI errors
07-eeh-report-race.patch When a PCI slot is isolated, all PCI functions under that slot are affected. If hese functions have separate device drivers, the EEH isolation event might be reported multiple times. This patch adds a lock to prevent the racing of such multiple reports. It also marks every device under the slot as having experienced an EEH event, so that multiple reports may be recognized more easily.
