holding kvm->arch.mmu_lock (typically with ``read_lock``, otherwise
there's no need to take kvm->arch.tdp_mmu_pages_lock at all).
- kvm->arch.mmu_lock is an rwlock. kvm->arch.tdp_mmu_pages_lock and
kvm->arch.mmu_unsync_pages_lock are taken inside kvm->arch.mmu_lock, and
cannot be taken without already holding kvm->arch.mmu_lock (typically with
``read_lock`` for the TDP MMU, thus the need for additional spinlocks).
Everything else is a leaf: no other lock is taken inside the critical
sections.
