Subject: [PATCH v1] KVM: arm64: Use the known cpu id instead of smp_processor_id()
Date: Thu, 27 Jul 2023 05:07:54 -0400 [thread overview]
Message-ID: <20230727090754.1900310-1-shahuang@redhat.com> (raw)
In kvm_arch_vcpu_load(), it has the parameter cpu which is the value of
smp_processor_id(), so no need to get it again. Simply replace it.
