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.
