#     powerpc/mm: dump block address translation on book3s/32
#     
#     This patch adds a debugfs file to dump block address translation:
#     
#     ~# cat /sys/kernel/debug/block_address_translation
#     Instruction Block Address Translations:
#     0:         -
#     1:         -
#     2: 0xc0000000-0xcfffffff 0x00000000 Kernel EXEC coherent
#     3: 0xd0000000-0xdfffffff 0x10000000 Kernel EXEC coherent
#     4:         -
#     5:         -
#     6:         -
