Subject: [PATCH resend 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

Thanks, will apply soon to kvm/queue.
