Rather than bisecting, I was rebasing my local customizations onto ZFS related
commits.

Looks like the culprit is "Update OpenZFS to 2.0.0-rc3-gfc5966"!

Interestingly I've also found https://github.com/openzfs/zfs/issues/11108 << a
recent issue mentioning non-canonical addresses (seems like Linux detects that
when handling faults), even if in a different context.

I'll report this to OpenZFS.
