Paolo, please pull these two patches for 6.7.

They introduce counters and a tracepoint into our nested VM page table
management code. Debuging nested page table management is notoriously
hard but the added low-overhead debug data will allow us to get a feel
for the problem before deploying deeper and higher overhead debugging
means.

I've held back the patches for a bit since we had suspicious CI fails
but they turned out to be unrelated and have been fixed at the end of
last week.
