packets. It's not clear whether latency will be affected much. It could be.
However, for the time being, getting full rates out of HIPPI or SCSI are what
interests us at NASA, so we'll hew to this bias.
* make map and alloc take 'flags' rather than 'cacheable,' for
more flexibility.
* rename BUS_BARRIER_* to BUS_SPACE_BARRIER_*, for consistency.
* rename bus_space_copy_* to bus_space_copy_region_* and make their
defns match the updated spec.
Backward compatibility is provided by defining __BUS_SPACE_COMPAT_OLDDEFS,
which is currently defined by default.
- Add entries for the LC520, Color Classic, and PB150 to intvid_info[].
- Make the PB150 a Duo-class machine, as it seems to work better this way.
Now that we're doing the latter, it points out something I missed a long
time ago when I added Duo support: CLASSDUO was being ignored in
mac68k_set_io_offsets().

anymore). This makes the code cleaner (no more bus tag guessing in the
serial console driver) and it allows to share code with KGDB port
initialization.
The console device is now given as string ("pc", "com0".."com3").
Modelled after alpha port.
Compute CPU speed(MHz) and loop multiplier for DELAY() based on
counting empty loop between mcclock ticks. New global: cpu_mhz.
Change pmax/pmax/machdep.c to build baseboard model names from cpu_mhz.
Set 'cpuspeed' for more realistic DELAY() on mips3 models.

* prototype and definition for pmap_activate(p). Updates the segtab,
and changes the active ASID if p == curproc.
* Make reserved fixed-address (UADDR) kernelstack PTEs global,
so we still have a kernel stack after pmap_activate() on curproc.
* make KSEG2 mappings for p_addr global (see above.)
Seems to detune contextswitch and NTP resolution (by 60 ms), but
thepmap_activate() interface is mandatory. Needs more thought.

Note that I only did this for the US type keyboard maps.
This and all other such options should be documented, and perhaps
rennamed with consistant PCCONS_ prefixes.
o option DISPLAY_ISO8859 enables the display of iso-latin1
character set (instead of the IBM page code 437)
o option FRENCH_KBD, GERMAN_KBD or NORVEGIAN_KBD implement
support for national keyboards (implies DISPLAY_ISO8859).

2) Add option PCCONS_REAL_BS which (for US keyboards only) forces
backspace to really be backspace and not delete. Intended to close
PR #2264 submitted by Greg Woods. He wanted it changed for everyone
-- I thought adding a kernel compile option was friendlier.
Note: Both of these sets of options really should be documented in an
i386 specific version of options(4).
(address error faults), as well as other reported problems:
- Simplify grfmv_phys() to work like grfiv_phys(), and eliminate the
second argument to both, as we don't use it anyway.
- Handle fbbase and fboff consistently throughout. Closes PR 3862.
- Eliminate grfaddr() by pulling it into grfmmap(), which is the
only place it was used, previously.
- grfmap() now gets the physical address of the framebuffer from
the appropriate driver, rather than try to compute it by itself.
Be careful with aligning the base to a page address and increase
the length of the mapped region appropriately. Closes PR 2867.
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
Removed some un-necessary cache synchronisations.
Call the cpu_sleep() function in an infinite loop in halt().
Removed the long dead swap specifier from rc7500 initarm().
the only timings we know are the ones inherited from the boot and the
drivers that will attach to the bus may change these.
Use the IS_PODULE macro for checking manufacturer and podule id's
against attach args.
