Subject: [PATCH 0/3] KVM: x86: sync SPTEs on page/EPT fault injection

This is my take on Junaid and Sean's patch, from the TLB cleanup series.
It passes initial tests, including my usual guest installation and
kvm-unit-tests battery (with both ept=0 and ept=1), but I'm not sure if
there's anything that isn't covered by kvm-unit-tests, especially for
nested.  I have not yet run guest installation tests under nested
virt but I will before merging the whole TLB cleanup series.

Please review!
