From: Christoffer Dall <cdall@xxxxxxxxxx> These two patches slightly improves our preemption configuration when accessing the per-CPU variables holding the currently running VCPU by removing a redundant check and rearranging calling code from non-preemptible context on RT systems. I'm not entirely sure if we fix issues only affecting PREEMPT_RT in mainline and also cc these to stable. Looking at the git log there seems to be some precedence for this. If not, I'm happy to remove the cc tag and/or drop the second patch.
