Yes, I think so.

Hrrm? I don't understand. If there are hugepages configured, all the
tests will run. If there are no hugepages, only the tests that can pass
without hugepages will run.

Sortof - if there aren't hugepages configured for an environment
reason (like unsupported) why get failure reports? Better to either
fail when we try to setup the hugepages, or skip when none are available
because they are two separate concerns.
