Hmm, since we flush the TLB on every nested-guest entry I think we can
make this function a nop.

I think, unless it specified ASID 0? In that case you need a local tlb flush.

(the kvm_mmu_reset_context() and kvm_mmu_load() are total overkills in any case).


Oh, but we do need to resync OOS pages, here for ASID 0 and on guest entry. Marcelo?
