#     powerpc/ps3: Fix kexec shutdown hang
#     
#     The ps3_mm_region_destroy() and ps3_mm_vas_destroy() routines
#     are called very late in the shutdown via kexec's mmu_cleanup_all
#     routine.  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.
