.. the main reason to use machdep.idle=hlt is that it is a different code path.
But to ensure you're always going via the hlt codepath, you _first_
have to disable mwait.
The idle code first decides whether to run mwait or <idle>, then if it
doesn't choose mwait, it chooses machdep.idle. That's why you first
have to disable idle_wait.
