[PATCH 5/5] arch_topology: Use cpumask_intersects where applicable

[Shrikanth Hegde <sshegde@linux.ibm.com>]

Looping over one cpumask and checking if any bit is set in another
cpumask is same as evaluating if two cpumasks intersects or not.

So use cpumask_intersects instead. It is probably faster too.
