This series introduce a fast-path when handling AVIC incomplete IPI #vmexit
for AVIC and x2AVIC, and introduce a new tracepoint for the slow-path
processing.

Please note that the prereq of this series is:
  [PATCH v2 00/12] Introducing AMD x2APIC Virtualization (x2AVIC) support
  (https://lore.kernel.org/lkml/20220412115822.14351-2-suravee.suthikulpanit@amd.com/T/)

Regards,
Suravee

Since x2AVIC stuff is still under development, and likely will need v3,
I will extract the logic for x2AVIC, and send out V2 of this series.
The support for x2AVIC will be send separately.
