Subject: [PATCH 0/2] KVM: x86: avoid potential soft lockup and unneeded mmu reload

This patch makes kvm_mmu_zap_all be preemptable since it is a slow path,
break the mmu-lock if needed to avoid potential soft lockup. Also it drops
unnecessary kvm_reload_remote_mmus

This is the preparing work about kvm_mmu_zap_all, the fast approach is being
developed

Xiao Guangrong (2):
  KVM: MMU: make kvm_mmu_zap_all preemptable
  KVM: MMU: drop unnecessary kvm_reload_remote_mmus
