Re: [PATCH] KVM: x86/mmu: Bug the VM, not the host kernel, if KVM write-protects upper SPTEs

[Paolo Bonzini]

Queued, thanks.  I adjusted the commit message to include Kai's
ovservation:

    Instead of bugging the host kernel, WARN and terminate the VM if KVM
    attempts to write-protect at a level that cannot use leaf SPTEs.
    There is no reason to bring down the entire host; even terminating
    the VM is likely overkill, but in theory a missed write could corrupt
    guest memory, so play it safe.
