Fixes and debug help for prove #VE support. I'm not in love with the sanity
check implementation, but I also don't love the idea of plumbing in @kvm to
the low level SPTE helpers.
Not super well tested, but I wanted to get this posted asap in case someone
wants to debug the unexpected #VEs we're seeing.
Note, Isaku's patch needs his SoB.
Isaku Yamahata (1):
KVM: x86/mmu: Use SHADOW_NONPRESENT_VALUE for atomic zap in TDP MMU
Sean Christopherson (8):
KVM: nVMX: Initialize #VE info page for vmcs02 when proving #VE
support
KVM: nVMX: Always handle #VEs in L0 (never forward #VEs from L2 to L1)
KVM: x86/mmu: Add sanity checks that KVM doesn't create EPT #VE SPTEs
KVM: VMX: Dump VMCS on unexpected #VE
KVM: x86/mmu: Print SPTEs on unexpected #VE
KVM: VMX: Don't kill the VM on an unexpected #VE
KVM: VMX: Enumerate EPT Violation #VE support in /proc/cpuinfo
KVM: x86: Disable KVM_INTEL_PROVE_VE by default
