Hi Paul, The patch below implements hotplug style EEH error recovery. Its split into two pieces: a part that needs to be applied to the PPC64 arch tree, and a part that needs to be applied to the RPA PHP hotplug tree. The PPC64 part needs to go in first. Assuming this doesn't generate a round of discussion, please forward upstream to akpm/torvalds. Signed-off-by: Linas Vepstas
