Subject: [PATCH 0/2] KVM: SVM: Optimize AVIC incomplete IPI #vmexit handling

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

  KVM: SVM: Introduce avic_kick_target_vcpus_fast()
  KVM: SVM: Introduce trace point for the slow-path of
    avic_kic_target_vcpus
