[PATCH 08/42] KVM: selftests: Drop redundant vcpu_set_cpuid() from PMU selftest

From: Sean Christopherson
Date: Fri Jun 03 2022 - 21:21:45 EST


Drop a redundant vcpu_set_cpuid() from the PMU test. The vCPU's CPUID is
set to KVM's supported CPUID by vm_create_with_one_vcpu(), which was also
true back when the helper was named vm_create_default().
