Description
AMD's Advanced Virtual Interrupt Controller (AVIC) offers similar functionality to APICv on Intel CPUs. It has the potential to drastically reduce VM exits for interrupt handling on the virtual APIC. We should wire up support for it on CPUs which possess that capability.

Further errata from AMD has suggested that use of AVIC is fraught with peril.
