Subject: [PATCH v3 0/5]  KVM: VMX: Clean up RTIT MAXPHYADDR usage
Date: Thu, 24 Sep 2020 12:42:45 -0700	[thread overview]
Message-ID: <20200924194250.19137-1-sean.j.christopherson@intel.com> (raw)

Stop using cpuid_query_maxphyaddr() for a random RTIT MSR check, unexport
said function to discourage future use, and do additional related cleanup.

Paolo, feel free to reorder/squash these as you see fit.  Five patches
feels more than a bit gratuitous, but every time I tried to squash things
I ended up with changelogs that ran on and on...

v2:
  - Rebased to kvm/queue, commit e1ba1a15af73 ("KVM: SVM: Enable INVPCID
    feature on AMD").

Sean Christopherson (5):
  KVM: VMX: Use precomputed MAXPHYADDR for RTIT base MSR check
  KVM: x86: Unexport cpuid_query_maxphyaddr()
  KVM: VMX: Replace MSR_IA32_RTIT_OUTPUT_BASE_MASK with helper function
  KVM: x86: Move illegal GPA helper out of the MMU code
  KVM: VMX: Use "illegal GPA" helper for PT/RTIT output base check
