'nobats' kernel parameter or some options like CONFIG_DEBUG_PAGEALLOC deny the use of BATS for mapping memory.
This patch makes sure that the specific wii RAM mapping function takes it into account as well.
Fixes: de32400dd26e ("wii: use both mem1 and mem2 as ram") Cc: stable@vger.kernel.org Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> --- Resending due to some servers not accepting 'umlaut' on Jonathan's family name. Sorry Jonathan.
