Subject: [PATCH 04/12] KVM: selftests: Use X86_PROPERTY_MAX_KVM_LEAF in CPUID test
Date: Thu, 6 Oct 2022 00:51:17 +0000 [thread overview]
Message-ID: <20221006005125.680782-5-seanjc@google.com> (raw)
In-Reply-To: <20221006005125.680782-1-seanjc@google.com>
Use X86_PROPERTY_MAX_KVM_LEAF to replace the equivalent open coded check
on KVM's maximum paravirt CPUID leaf.
No functional change intended.
