You might put some evidence that we're suffering from contention here
(I'm very willing to believe it, but hard evidence is better).
Don't have any evidence yet, the main purpose of the split is to fix the

You might have said that.
But, with the data we have so far, slots_lock and kvm->lock will cause
significant cache bouncing on EPT hardware (with measurements on shadow
mmu_lock is #1 offender).
Well, mmu_lock is probably contended, which is much worse than just
cache bouncing.
