Sean Christopherson e89505698c KVM: x86/mmu: Commit zap of remaining invalid pages when recovering lpages ... Call kvm_mmu_commit_zap_page() after exiting the "prepare zap" loop in kvm_recover_nx_lpages() to finish zapping pages in the unlikely event that the loop exited due to lpage_disallowed_mmu_pages being empty. Because the recovery thread drops mmu_lock() when rescheduling, it's possible that lpage_disallowed_mmu_pages could be emptied by a different thread without to_zap reaching zero despite to_zap being derived from the number of disallowed lpages.
