Right, and SMP_CACHE_BYTES setting should save us in any case.

For ARM, SMP_CACHE_BYTES seems to be set to L1_CACHE_BYTES which in
turn is set via ARM_L1_CACHE_SHIFT which can be set seemingly to any
value but the defaults are 5 and 6 which should be OK.

So unless Tony is using a non-standard setting of ARM_L1_CACHE_SHIFT,
this report is a bit mysterious.
