#     powerpc/fixmap: Fix the size of the early debug area
#     
#     Commit ("03fd42d458fb powerpc/fixmap: Fix FIX_EARLY_DEBUG_BASE when
#     page size is 256k") reworked the setup of the early debug area and
#     mistakenly replaced 128 * 1024 by SZ_128.
#     
#     Change to SZ_128K to restore the original 128 kbytes size of the area.
#
