If you use sys/param.h, you don't need sys/types.h

ansi functions

Don't need LINEAR mappings.

Add a "where" argument to the sparc64 interrupt code. This lets us
associate a name with each interrupt handler. This is not visible
outside the kernel (yet).

Nuke my clause 3 and 4 (and a couple of files jointly (c) with Theo).

Add support for the Sun Enterprise 450
Reduce the size of a GENERIC kernel by ~190k

Add support for the Sun Enterprise 450
Reduce the size of a GENERIC kernel by ~190k
Remove the nasty pointer/bus_space_handle_t casts
Adds debug bus_space code including the ability to trace
bus operations (it actually works now).

The following rules are now followed (and verfified by the debug
code):

1. A "bus_space_handle_t" may only be used with the
"bus_space_tag_t" that created it.
2. Only "bus_space_map()" may create "bus_space_handle_t"s.
3. A "bus_space_handle_t" may not be modified after it has
been created (other than being destroyed by "bus_space_unmap()").


Thanks to help from mcbride, marc, jason, drahn, to anyone that might
have slipped my mind at the moment.

ok jason@, deraadt@
