cdevsw[]->d_ttys must be initialized
XXstop() functions must be callable from cdevsw[]->d_stop
the console tty is used before vm system is up, and must
allocate it's own clists..
automatically now, but have not checked.
l_ioctl() has no last parameter 'p'
fb.c: move sys/fbio.h to machine/fbio.h
various: typecast parms for timeout() properly
zs.c: extra level of indir in cdevsw[]->d_ttys
+ lots of temp changes to be backed out later!
DEBUG=-g always, use gcc, link with libgcc.a, include dirs in
a weird place for my development environment.
cpu.h: cpu_adjstack() won't work well in the NetBSD execve - need a
different model, stub enablertclock() for now..
exec.h: a netbsd-type exec.h file (ie. empty)
param.h: add MID_MACHINE
pmap.h: delete kernel_pmap hack - it doesn't work for us, + two proto's
vmparam.h: VM_MIN_ADDRESS = 0!
autoconf.c: mountroot kludges that need fixing later
clock.c: two volatile decls
conf.c: stategy()'s return void, *tty[] not tty[], __P()'d xxdump() calls,
add mem_no, *constty[] not &cons.
genassym.c, machdep.c: sys/vmmeter.h needed
intr.c: make kernel writable temporarily in intr_fasttrap()
intr.c: do not use NETISR_ARP
locore.s: icode maps at 0 so do not relocate, don't define __main here.
machdep.c: don't have sysctl.h (yet), use vm_page_free_count for freemem,
setregs() sets pc/npc/stack, note: signal delivery code needs
fixing, add various other NetBSD function stubs.
pmap.c: do kernel_pmap/kernel_pmap_store the old way, delete
vm_page_startup_initialized weirdness.
swapgeneric.c: everything about mountroot needs fixing, help.
trap.c: sunsys -> sun_sysent, etc.
vm_machdep.c: don't use cpu_coredump() for now.
