[PATCH 07/15] KVM: selftests: Capture per-vCPU GPA in perf_test_vcpu_args

From: Sean Christopherson
Date: Wed Feb 10 2021 - 18:10:18 EST


Capture the per-vCPU GPA in perf_test_vcpu_args so that tests can get
the GPA without having to calculate the GPA on their own.

No functional change intended.
