It is possible that stale EPTP-tagged mappings are used, if a

Set KVM_REQ_TLB_FLUSH in vmx_vcpu_load, when switching pcpus, which

Thank you - I was at the brink of a nervous break-down before discovering
this. Maybe it would help for the future to add a comment to
ept_misconfig_inspect_spte that explains that this might be caused by out of
sync tlbs, too (esp. when it doesn't show an apparent cause of the misconfig)
In fact ept_misconfig_inspect_spte() was added in order to track down
this bug, so it will probably be removed in the future.
