[PATCH v3 0/5] KVM: VMX: Clean up RTIT MAXPHYADDR usage

From: Sean Christopherson
Date: Thu Sep 24 2020 - 15:43:19 EST


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
