Could you explain whey move the r13 check out of mca_recover_range()?

Just a picky comment...Is it better to changed to
+ if (mca_cpu!=0) {
+		for_each_online_cpu(i) {
+			if (cpu_isset(i, mca_cpu)) {
+				monarch_cpu = i;
+				cpu_clear(i, mca_cpu);	/* wake next cpu
*/

it may speed up a bit?. After all in reality, there are few bits set in
mca_cpu. So there is no need to go through all of online cpus.

Thanks.
