This is my cleaned up version of Wanpeng's TSC deadline timer optimizations. The main change is a reorganization of the fast path enums, removing EXIT_FASTPATH_SKIP_EMUL_INS (following the suggestion of 林鑫龙) and renaming EXIT_FASTPATH_NOP to EXIT_FASTPATH_EXIT_HANDLED.
Paolo Bonzini (1): KVM: x86: introduce kvm_can_use_hv_timer
Wanpeng Li (6): KVM: VMX: Introduce generic fastpath handler KVM: X86: Introduce kvm_vcpu_exit_request() helper KVM: X86: Introduce more exit_fastpath_completion enum values KVM: VMX: Optimize posted-interrupt delivery for timer fastpath KVM: X86: TSCDEADLINE MSR emulation fastpath KVM: VMX: Handle preemption timer fastpath
