The Cafe chip only appeared in the OLPC XO-1 and cannot even come close to doing S/G I/O. So this patch robs a bit of memory for no use on a platform that can ill afford it. OTOH, the number of people building contemporary kernels for the XO-1 has got to be pretty small. So, in the interest of mollifying randconfig users out there, you can add my: Acked-by: Jonathan Corbet <cor...@lwn.net> jon -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
