At the moment, NetBSD/arm32 creates a /dev/cpu0 and /dev/cpu1.  These
devices can be opened and closed (only one process is allowed to have each
one open at a time).  ioctls always return ENXIO.  All other operations
return ENODEV.  This has been the case since the beginning of time.

I propose removing support for these devices from the kernel.  Whatever
functionality they were intended to have clearly never materialised, and
CPU operations seem to be being provided by sysarch() IMB these days.  No
other architecture has /dev/cpu*.  Any dissent?
