8900ab37e3 clean up, move some XXX's around, and note that one or two things should be 
replaced with timeval{add,sub}, and generally be made more sane.

7a7e6dbd95 removed slip and ppp specific prototypes from tty.h where they didn't belong. 
moved them to tty_conf.c within #if Nwhatever > 0 where they do belong.
made sure that if_sl.c, and if_ppp.c still compile quietly.

b73e5e6647 kill the process 'space' accounting collection for the following reasons: 
(1) text calculation incorrect (would 'overbill')
	(2) data calculation incorrect (would 'overbill')
	(3) the maxrss calculation uses stuff which isn't present
		on the sparc.
if 3/4 tests are questionable and/or broken, well...

436e431478 BSDI official patch #15: 
SUMMARY:
    "panic: vrele: null vp", the problem seems to be that two renames are
    moving the same source, and the second one can't do it.
ALSO:
    in sync, check that rootfs is non-null before using it.

299ff91b14 BSDI official patch #14: 
SUMMARY:
    Here is a patch for a kernel hang that can be provoked with a write
    or send of a negative amount.  The talk program is capable of exercising
    this bug.  This patch also includes a fix for a bug that caused data
    to be delivered to TCP in smaller chunks than desired, and which caused
    TCP to send a short packet when starting up.  Finally, there is a bug
    fix for MSG_PEEK with an oobmark pending.

287eb9a50e delete my '/dev/acct'-style accounting in favor of the version written by 
Mark Tinguely (tinguely@plains.NoDak.edu).  It's the 'standard' way
of doing accounting, rather than a wacky one.

a84055b552 use the ALIGN macro to align the stack, rather than rounding up 
by a (char *).  the former is safe, even on strange machines

772436479d new, improved, and rationally-implemented vfs_bio. no more serious 
structural changes should happen, as it now does the right thing
w.r.t. buffer resizing and having lots of buffers vs. relatively
little buffer space.  Ports can now "do the standard thing", re:
nbuf and bufpages, which is make nbuf = bufpages by default.

1d0f22a29a convert to use the buffers which are (now) statically allocated at 
startup in machdep.c...  buffers are now *never* allocated after boot.
currently, the limitation that says bufpages must cover nbuf*MAXBSIZE
still exists, but this is one step closer to removing that limitation.

de69711383 These changes are due to a mismatch with user functions prototyped as 
func(short) and the fact the the kernel uses full ints.  This caused
problems on the pc532 port.  These fixes take the good 16 bits passed
by the user program and converts them into the correct form for the
kernel.

15359c9f59 enable loadable execution handlers. need to do something better re: 
how much of the file to pass in the exec package, but i think the
solution to that will be to pass e.g. a disk block's worth, or whatever;
if exec handlers really need more, they've got the damned vnode.

fddf2c7605 ptrace_single_step() and ptrace_set_pc() should return errors if 
necessary.  (Mainly because the SPARC can't easily single step, so
it should return EINVAL, and then ptrace() should return that to the
user.)
