Drop it for good. It only showed minimal benefit on ia64 (however, 3% on i386). I am working on something different that uses temporal and nontemporal stores for clearing pages. It will add a clear_cold function that can zero higher order pages using nontemporal stores in order to avoid thrashing the cache. No clear_page/clear_pages anymore. - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
