Flushing ept tlbs of several address range can be done via single hypercall and new list flush function is used in the kvm_mmu_commit_zap_page() and FNAME(sync_page). This patchset also adds more hv ept tlb range flush support in more KVM MMU function. Lan Tianyu (11): X86/Hyper-V: Add parameter offset for hyperv_fill_flush_guest_mapping_list() KVM/VMX: Fill range list in kvm_fill_hv_flush_list_func() KVM: Add spte's point in the struct kvm_mmu_page KVM/MMU: Introduce tlb flush with range list KVM/MMU: Flush tlb directly in the kvm_mmu_slot_gfn_write_protect() KVM/MMU: Flush tlb with range list in sync_page() KVM: Remove redundant check in the kvm_get_dirty_log_protect() KVM: Make kvm_arch_mmu_enable_log_dirty_pt_masked() return value KVM/MMU: Flush tlb in the kvm_mmu_write_protect_pt_masked() KVM: Add flush parameter for kvm_age_hva() KVM/MMU: Flush tlb in the kvm_age_rmapp() arch/arm/include/asm/kvm_host.h | 3 +- arch/arm64/include/asm/kvm_host.h | 3 +- arch/mips/include/asm/kvm_host.h | 3 +- arch/mips/kvm/mmu.c | 8 +++- arch/powerpc/include/asm/kvm_host.h | 3 +- arch/powerpc/kvm/book3s.c | 3 +- arch/powerpc/kvm/e500_mmu_host.c | 3 +- arch/x86/hyperv/nested.c | 4 +- arch/x86/include/asm/kvm_host.h | 11 +++++- arch/x86/include/asm/mshyperv.h | 2 +- arch/x86/kvm/mmu.c | 73 ++++++++++++++++++++++++++++++++----- arch/x86/kvm/paging_tmpl.h | 18 ++++++++- arch/x86/kvm/vmx/vmx.c | 18 ++++++++- include/linux/kvm_host.h | 2 +- virt/kvm/arm/mmu.c | 8 +++- virt/kvm/kvm_main.c | 18 ++++----- 16 files changed, 141 insertions(+), 39 deletions(-)
