From 10f0b222ea7e0ab90e7c72a255ce8e4f284b12e3 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Mon, 18 Apr 2022 11:28:15 -0700 Subject: [PATCH] KVM: selftests: Convert system_counter_offset_test away from VCPU_ID Convert system_counter_offset_test to use vm_create_with_one_vcpu() and pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
