For example an SSE version will at least assume 16 byte alignment, etc etc. clear_page() is supposed to be for full real pages only... for example it allows the architecture to optimize for alignment, cache aliasing etc etc. (and if there are cpus that get a "clear an entire page" instruction.... there has been hardware like that in the past, even on x86, just it's no longer sold afaik) -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
