KVM: VMX: Add ept_sync_context in flush_tlb
Fix a potention issue caused by kvm_mmu_slot_remove_write_access(). The old behavior don't sync EPT TLB with modified EPT entry, which result in inconsistent content of EPT TLB and EPT table. Signed-off-by: Sheng Yang <sheng.yang@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
