[PATCH] ARC: Adjust cpuinfo for non-continuous cpu ids

From: Noam Camus
Date: Tue Oct 18 2016 - 10:02:07 EST


From: Noam Camus <noamc@xxxxxxxxxx>

num_possible_cpus() returns how many CPUs may be present on system.
However we want the highest possible CPU number.
This may be differ in a sparsed possible CPUs map.
