I think Christoph's variable order pagecache should be perfectly fine on ppc64. We're selecting the pagesize on a per-file basis, and the page size selection would choce which segement this mmap gets into. Ben's get_unmapped_area changes are very helpfull for that. - 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/
