max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new
situation. The larger buffers are required by the very high speed
KDDI devices in Japan (CF com, or USB ucom) so those are the only two
drivers which currently ask for a larger buffer size.

which contains the constraints for DMA/memory allocation for each
architecture, and dma_constraints which contains the range of addresses
that are dma accessable by the system.
This is based on ariane@'s physcontig diff, with lots of bugfixes and
additions the following additions by my self:
Introduce a new function pool_set_constraints() which sets the address
range for which we allocate pages for the pool from, this is now used
for the mbuf/mbuf cluster pools to keep them dma accessible.
The !direct archs no longer stuff pages into the kernel object in
uvm_km_getpage_pla but rather do a pmap_extract() in uvm_km_putpages.
Tested heavily by my self on i386, amd64 and sparc64. Some tests on
alpha and SGI.

it defines. In some cases, this means pulling in uvm.h or pcb.h
instead, but most of the inclusions were just noise. Tested on
alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax,
mostly by krw and naddy.

a fat kernel (GERERIC or GENERIC.MP) into a temporary dir, then extract some
variables using make -V, and after some more singing and dancing use this
full and (more) correct list of files with ctags. Don't read this code.

the differences between these files. You will need a newer config(8) binary
to be able to build kernels.

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.
The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.
This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on. You can still screwed really easily, so continue running make
depend as config tells you.

On AViiON systems with the 6:1 CMMU:CPU configuration, force cached
mappings to be writethrough - this probably hides a bug in the code, but
that's the only way so far to get such a system running stably.

two directories. in reality, because of how we place files, it has four:
.../arch/A, .../arch/A/A, .../arch/M, and .../arch/M/M
formalize this A/A and M/M scheme directly in the Makefiles, which makes
them a lot more similar

4000 and 4300 will need more work, because they don't have as many distinct
software interrupt sources as required by this implementation, so a
different IPI scheme will be necessary.
Tested on dual-processor 4625 (AV530 family) and single processor 4300
(AV400 family).

/usr/opt/sdk/include/sys/dg_sys_info.h on a DG-UX filesystem).

board-specific defines to prevent any risk of collision. This also adds
clock support for AV530 family, and timecounter support (cio code sync'ed
with mvme88k). And various bugs fixed in the process.
This is enough to get models 4600 and 530 to run multiuser with a Hawk
Ethernet VME card (the onboard Ethernet is not supported yet, coming soon).
There is no way to share a disk with DG/UX yet, the kernel (and fdisk(8))
needs to become aware of its ways.

Also features support for {awkw,bast}ard 6:1 CMMU:CPU configurations (4I2D).
Tested on model 4605, which runs up to cpu_initclocks(), which is not written
for this system family yet. No regression on model 4300.

to be 00:00:00:00:00:00 if `-z' is passed; this allows netboot to work on a
machine which has lost its nvram (despite the ethernet address not being
stored in nvram at all, stupid prom can't be bothered to get it right...).
Crank netboot version.
