That puts constraints on where the platform may align physical memory. 32M may not be unreasonable (Can you even buy DIMMS that small anymore?) But 64G is way too large. Since we only deal with blocks of memory in IA64_GRANULE_SIZE pieces (16M or 64M) that would seem to be the natural skip amount. -Tony - : send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
