Subject: KVM: PPC: Book3S PR: Emulate TIR register
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5948fa092a04dfd6b9ee31c99eb6896c158eb08;p=linux-beck.git

KVM: PPC: Book3S PR: Emulate TIR register

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.
