  KVM: nVMX: Add a sanity check that nested PML Full stems from EPT Violations (2024-04-09 10:24:36 -0700)

----------------------------------------------------------------
KVM VMX changes for 6.10:

 - Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to
   L1, as per the SDM.

 - Move kvm_vcpu_arch's exit_qualification into x86_exception, as the field is
   used only when synthesizing nested EPT violation, i.e. it's not the vCPU's
   "real" exit_qualification, which is tracked elsewhere.

 - Add a sanity check to assert that EPT Violations are the only sources of
   nested PML Full VM-Exits.
