#     powerpc/64s: Default l1d_size to 64K in RFI fallback flush
#     
#     If there is no d-cache-size property in the device tree, l1d_size could
#     be zero. We don't actually expect that to happen, it's only been seen
#     on mambo (simulator) in some configurations.
#     
#     A zero-size l1d_size leads to the loop in the asm wrapping around to
#     2^64-1, and then walking off the end of the fallback area and
#     eventually causing a page fault which is fatal.
#     
#     Just default to 64K which is correct on some CPUs, and sane enough to
#     not cause a crash on others.
#     
#     Fixes: aa8a5e0062ac9 ('powerpc/64s: Add support for RFI flush of L1-D cache')
