By the time mmu_cleanup_all runs it is too late to use # udbg_printf, and calling it will cause PS3 systems to hang. # # Remove all debugging statements from ps3_mm_region_destroy() and # ps3_mm_vas_destroy() and replace any error reporting with calls # to lv1_panic. # # With this change builds with 'DEBUG' defined will not cause kexec # reboots to hang, and builds with 'DEBUG' defined or not will end # in lv1_panic if an error is encountered. # # Signed-off-by: Geoff Levand # Signed-off-by: Michael Ellerman # Link:
