We ran into a big problem with this on x86-64. The SUSE installer would load the floppy driver during installation. Floppy driver would try to allocate some pages with GFP_DMA and on a small memory x86-64 system (256-512MB) the OOM killer would always start to kill things trying to free some DMA pages. This was quite a show stopper because you effectively couldn't install. So at least for GFP_DMA it seems to be definitely needed. -Andi - 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/
