Takuya Yoshikawa b3ae209697 KVM: Introduce kvm_unmap_hva_range() for kvm_mmu_notifier_invalidate_range_start() ... When we tested KVM under memory pressure, with THP enabled on the host, we noticed that MMU notifier took a long time to invalidate huge pages. Since the invalidation was done with mmu_lock held, it not only wasted the CPU but also made the host harder to respond. This patch mitigates this by using kvm_handle_hva_range().
