were always in a tss; that tss just changed from the one in the
pcb to common_tss (who knows where it was when there was no curpcb?).
Not using the pcb also fixed the problem that there is no pcb in
idle(), so we now always get useful register values.
same directory pair.
If we do:
mount -t union a b
mount -t union a b
then, (1) namei tries to lock fs which has been already locked by
first union mount and (2) union_root() tries to lock locked fs. To
avoid first deadlock condition, unlock vnode if lowerrootvp is union
node, and to avoid second case, union_mount returns EDEADLK when multi
union mount is detected.
for the ix driver.
Add a shutdown hook that resets the etherexpress so that Windoze can find
the card after a warm boot.

This patch has been submitted by Andreas Burmester (i think) on the
German Usenet long ago. Andreas told me that our m4 has quite more
subtle bugs, so we might consider using NGU m4 instead.
switching to a child for the first time was being counted twice. I think
this only affected unimportant statistics.
Simplified arg handling in fork_trampoline(). splz() doesn't actually
smash the registers of interest.
Use _BSD_OFF_T_ instead of off_t so that we're still self-sufficent.
Copied the ftruncate/lseek()/mmap()/truncate() redeclaration hacks
from <sys/types.h> so that things depending on them don't break.
cause noise.
Duplicated the lseek() redeclaration hack for all functions involving
off_t's (ftruncate(), mmap() and truncate()) to help broken programs
work.
<machine/types.h> gets redefined in the non-GNU and non-ANSI cases.
Since this hasn't caused problems, there must be no one actually
benefitting from the obfuscations supported by <sys/cdefs.h>.
`make CC="cc -traditional"' in /usr/src/bin shows the same. Almost
everything is broken in essentially the same way - `const' is used
in strings before <sys/cdefs.h> is included, so `const' is not
#defined away until after it is used.
Fixed some style bugs.
TTY_NETWORK (network), TTY_DIALUP (dialup), which determine a basic
connection type. TTY_DIALUP in particular will replace the old out of
date heuristic "tty[dD]*" in login.c (and better than the current
hard-coded method).
