> runq: Deduce most parameters, remove machine headers
>
> The 'runq' machinery now depends on only two settable parameters,
> RQ_MAX_PRIO, the maximum priority number that can be accepted, the
> minimum being 0, and RQ_PPQ, the number of priorities per queue (to
> reduce the number of queues).
>
> All other parameters are deduced from these ones. Also, all
> architectures automatically get a runq word that is their natural word.
>
> RQB_FFS() always was 'ffsl() - 1' except for amd64 where it was
> 'bsfq()'. Now that all these finally call compiler builtins, the
> resulting assembly code is the same, so there is no cost to removing
> this special case.
>
> After all these changes, <machine/runq.h> headers have no more purpose,
> so remove them.
>
> While here, fix potentially confusing parameter name for RQB_WORD() and
> RQB_BIT().
>
> While here, include all necessary headers so that <sys/runq.h> can be
> included standalone.
>
> No functional change (intended).

make buildworld is broken on arm64. Is this missing?
