Interesting. Using __get_free_pages guarantees that the pages are physically contiguous. Does the new ARM version do something clever to get physically contiguous pages? Or do the callers have to do a scatter/gather type of operation if they are using more than 1 page? Paul. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
