It isn't clear that it ever worked, if it did it has almost certainly
bitrotted in the last 12 years. I'm not even sure all the required
components were present.
I suspect it was written to attempt to use a 'farm' of diskless sun3s.
In any case the apparant random assignment fo jobs to other systems doesn't
actually seem like a good idea!
Things like 'distcc' han be used to help slow systems run native builds.
Removing this code also simplifies make, and should let me speed up some of
its processing - without worrying about bitrotting it further.
is not specified. This is because it prints getgid() and getgroups(). If the
getgid() is in the getgroups() set, it was printed twice. This is now detected
and the duplicate printing is avoided.
FROMBCD()/TOBCD() macros into wrappers around it, resulting in both
smaller code footprint and elimination of possible issues due to
multiple evaluation of macro arguments.

moving system call functionality from trap.c to new syscall.c
Split out userret from trap.c to <machine/userret.h> and use
mi_userret().
This gets approx 20% speed improvement (45us to 36us) with lmbench's
"lat_syscall null" benchmark(!).
The tadpole microcontroller sets an additional bit in frame headers from
an external mouse which caused our driver to discard the frame - now we
just ignore the bit.
the TOY register, which is presumed to be seconds since Jan. 1 2000.
For now I'm assuming the trim divider is 32K, which makes 1 tick per sec.
This is true for the DBAU1550 board at least. Other boards might need to
initialize a reasonable trim counter and establish the 32KHz oscillator.
In any case, this code is *no worse* on older systems than what was there
before.
1) create new pnpbus psuedo bus. This is a bus layer that reads the PNP
tree from the residual data and allows attachment of devices with the
information given therein. Based loosely on i386/pnpbios.
2) Delete obio bus, as with the pnp bus we no longer need it.
3) Create a number of functions that gather the information needed to set
up the machine from the residual data, rather than hardcoding it in.
4) Create a quirk table for machines that are bizzare enough that the
residual information is not sufficient. (such as the 6015)
5) Using the data gathering routines and the quirk table, delete struct
platform completely from the architecture. Prep is now almost completely
dynamic in figuring out the machine it is running on and setting things
up properly.
6) Add a wdc_pnpbus driver which attaches the wdc controller found on
some 7248's and the 6015. This replaces the now-defunct wdc_obio.
7) delete all the mot_* and ibm_* files, and replace them with a single
ibm_machdep.c which only contains the quirk functions for the 6015 and
the 6050.
8) Modify GENERIC to work with all this stuff.
