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.
