#     powerpc/64s: Add MMU type to __die() output
#     
#     On Power9 machines (64-bit Book3S), we can be running with either the
#     Hash table or Radix tree MMU enabled. So add some text to the __die()
#     output to tell us which is enabled, for the case where all you have is
#     the oops output and no other information.
#     
#     Example output:
#     
#       kernel BUG at drivers/misc/lkdtm/bugs.c:63!
#       Oops: Exception in kernel mode, sig: 5 [#1]
#       LE PAGE_SIZE=64K MMU=Hash SMP NR_CPUS=2048 NUMA pSeries
