Subject: [PATCH v5 0/7] KVM: VMX: Tscdeadline timer emulation fastpath

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
