Subject: [PATCH v5 0/6] KVM: nVMX: Enable nested apicv support

v1 ---> v2:
  Use spin lock to ensure vmcs12 is safe when doing nested
  posted interrupt delivery.

v2 ---> v3:
  1. Add a new field in nested_vmx to avoid the spin lock in v2.
  2. Drop send eoi to L1 when doing nested interrupt delivery.
  3. Use hardware MSR bitmap to enable nested virtualize x2apic
     mode.

v3 ---> v4:
  1. Optimize nested msr bitmap merging.
  2. Allocate nested msr bitmap only when nested == 1.
  3. Inline the nested vmx control checking functions.

v4 ---> v5:
  1. Move EXIT_REASON_APIC_WRITE to the apic register
     virtualization patch.
  2. Accomplish nested posted interrupts manually if
     they are not recognized by hardware.

Wincy Van (6):
  KVM: nVMX: Use hardware MSR bitmap
  KVM: nVMX: Enable nested virtualize x2apic mode
  KVM: nVMX: Make nested control MSRs per-cpu
  KVM: nVMX: Enable nested apic register virtualization
  KVM: nVMX: Enable nested virtual interrupt delivery
  KVM: nVMX: Enable nested posted interrupt processing
