We were talking about 8xx, not 82xx -- is it always identity mapped there? If so, then why bother with the ioremap in immr_map_size() in arch/ppc/8xx_io/commproc.c? And why compare the result from ioremap() with a raw identity-mapped address? -Scott - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
