using a NetBSD kernel in an ultrix root filesystem.
Move wait emulation to the old (v7) wait syscall number, as that's
what the Ultrix ufs_mount binary uses.
limit the number of FDs to select on to the maximum supported by NetBSD --
which is as many FDs as the emul_ultrix process can have open, anyway.
Add emulation of Ultrix getmnt(2) in ultrix_fs.c
Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived
from compat/sunos/sunos_ioctl.c. Ultrix libc's ``isatty()'' now works
in compat_emul processes.

to time out the boot prompt. Now uses a usleep() routine that calls
the BIOS and the functionality is separate from gets(). Timeout is
#defined to 5 seconds. Also did some minor cleanup in preparation to
prototype/ANSIfy everything.
* define PT_GETREGS and PT_SETREGS in pmax/include/ptrace.h
* Flesh out the stubs in pmax/pmax/process_machdep.c to handle
those requests.
* Now that "struct reg" is actually used, remove the bogus
#ifdef LANGUAGE_C around its definition, and redo pmax/include/reg.h
so that the definitions needed by locore.S are in a separate file,
pmax/include/regnum.h.
* update locore.S to match.
also defines tc device. does _not_ define le driver, because
of conflicts with other (e.g. ISA) le drivers. (Alpha kernel
configuration files include files.isa and files.tc.)
should work properly with:
(1) LANCE chips hanging off the system IOCTL asic,
(2) LANCE chips TurboChannel option boards.
Support for various PMAX-family baseboard options isn't yet in this
file, but should be easy to add.
deal with stuff like:
(1) configuring built-in devices,
(2) looking at TC slots configuring any devices found.
The lists of slots, slot locations, etc. and built-in devices
are provided by machine-dependent code. Interrupt handling
is also provided by machine-dependent code, but the MD code provides
hooks so that standard names for 'establish' and 'disestablish'
can be used in drivers.
This code requires <machine/tc_machdep.h>, which defines some
portability types specific to the TurboChannel bus code.
