Only exists in drivers/cpuidle/governors/menu.c, and still would need a do_div to avoid the subsequent 64-bit division. The choice appears to be either perform the divide by 1000 using do_div, or note that a u32 * 128 / 1000 is also a u32 and so cast the result of DIV_ROUND_UP_ULL back to u32. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
