    Subject[RFC PATCH v5 041/104] KVM: VMX: Move setting of EPT MMU masks to common VT-x code
    Date
    From: Sean Christopherson <sean.j.christopherson@intel.com>

    EPT MMU masks are used commonly for VMX and TDX. The value needs to be
    initialized in common code before both VMX/TDX-specific initialization
    code.
