miss bad address handler saving nonvolatile GPRs # # The SLB bad address handler's trap number fixup does not preserve the # low bit that indicates nonvolatile GPRs have not been saved. This # leads save_nvgprs to skip saving them, and subsequent functions and # return from interrupt will think they are saved. # # This causes kernel branch-to-garbage debugging to not have correct # registers, can also cause userspace to have its registers clobbered # after a segfault. # # Fixes: f0f558b131 ("powerpc/mm: Preserve CFAR value on SLB miss caused by access to bogus address") # Cc:
