Subject: [PATCH 0/3] KVM: VMX: Clean up RTIT MAXPHYADDR usage
Date: Wed, 15 Jul 2020 20:44:05 -0700 [thread overview]
Message-ID: <20200716034408.6342-1-sean.j.christopherson@intel.com> (raw)
Stop using cpuid_query_maxphyaddr() for a random RTIT MSR check and
unexport said function to discourage future use.
Sean Christopherson (3):
KVM: VMX: Use precomputed MAXPHYADDR for RTIT base MSR check
KVM: VMX: Replace MSR_IA32_RTIT_OUTPUT_BASE_MASK with helper function
KVM: x86: Unexport cpuid_query_maxphyaddr()
