The idea to shift/share mmu cache memory between guests is great.
You do need to take care of proper inter vm locking (kvm_lock lock,
don't mix the kvm->lock).
Combining the idea with LRU replacment algorithm and a rebalance timer
for the mmu cache can
be a winning combination.

No, we need to stay away from kvm_lock on anything resembling a hot path.
