Sure. Building it now.

I missed this previous time. Should this be !pmap_every_pte_zero() ?

Correct a mistakenly inverted condition.

Yes, you are correct. I will commit the fix to amd64 and arm64 shortly.

So far, I have seen two (unrelated?) problems while testing with D22890.65867.diff:
https://people.freebsd.org/~pho/stress/log/alc012.txt
https://people.freebsd.org/~pho/stress/log/alc013.txt
I have resumed the tests.

alc012 seems to be either KVA fragmentation or depletion.
alc013 should be not related, I will look into it later.

I completed testing D22890.65867.diff without seeing any problems. The test included a buildworld.
