chenhui zhao ebb9d30a6a powerpc/mm: any thread in one core can be the first to setup TLB1 
On e6500, in the case of cpu hotplug, either thread in one core
may be the first thread initilzing the TLB1. The subsequent threads
must not setup it again.

The code is derived from the comment of Scott Wood.
