From: Lan Tianyu <Tianyu.Lan@xxxxxxxxxxxxx>
This patchset is to introduce hv ept tlb range list flush function
support in the KVM MMU component. 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.
Change since v1:
1) Make flush list as a hlist instead of list in order to
keep struct kvm_mmu_page size.
2) Add last_level flag in the struct kvm_mmu_page instead
of spte pointer
3) Move tlb flush from kvm_mmu_notifier_clear_flush_young() to kvm_age_hva()
4) Use range flush in the kvm_vm_ioctl_get/clear_dirty_log()
Lan Tianyu (10):
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/MMU: Add last_level in the struct mmu_spte_page
KVM/MMU: Introduce tlb flush with range list
KVM/MMU: Flush tlb with range list in sync_page()
KVM/MMU: Flush tlb directly in the kvm_mmu_slot_gfn_write_protect()
KVM: Add kvm_get_memslot() to get memslot via slot id
KVM: Use tlb range flush in the kvm_vm_ioctl_get/clear_dirty_log()
KVM: Add flush parameter for kvm_age_hva()
KVM/MMU: Use tlb range flush in the kvm_age_hva()
