3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit a5948fa092a04dfd6b9ee31c99eb6896c158eb08 upstream.
In parallel to the Processor ID Register (PIR) threaded POWER8 also adds a
Thread ID Register (TIR). Since PR KVM doesn't emulate more than one thread
per core, we can just always expose 0 here.
