Our vput calls vm_object_deallocate() --> vm_object_terminate(). The
vm_object_terminate() calls vn_lock(), since UN_LOCKED has been
already cleared in union_unlock(). Then, union_lock locks upper vnode
when UN_ULOCK is not set. The upper vnode is not unlocked when
UN_KLOCK is set in union_unlock(), thus, union_lock tries to lock
locked vnode and we get panic.
(ignored :-() errors for `make depend' in /sys/i386/boot/*. It's
natural for there to be no libraries there and inconvenient to check
for this in bsd.prog.mk.
if SCB Paging was enabled:
disconnect with more data to transfer
disconnected SCB gets paged out
target reconnects so we page SCB back in
target completes transfer so residual is 0
target disconnects
SCB gets reused but not paged out since the residual is 0 (optimization)
target reconnects so we page the SCB back in
we report a residual because of stale residual information.
The fix for this is to set a flag that forces the SCB to be paged back
up to the host if we page in an SCB with a residual

Fix another bug: if argv[0] is NULL, garbadge args might be added for

for syscalls, so one frame was lost in backtraces from syscalls.
This is handled better in the kernel by using a different mcount
entry point for profiling before the frame pointer is set up.
Expand RCSID().
Use .p2align instead of the ambiguous .align.
Added idempotency ifdef.
Removed unused macros ALTENTRY(), ALTASENTRY(), ASENTRY(), _MID_ENTRY.
Cleaned up formatting.

- dependencies actually work (I need this to propagate some fixes
in <machine/asm.h>)
- the cpp pipeline goes away, so errors can't leak out of it and
an ANSI cpp is automatically used.
- it's simpler - standard rules get used instead of repetitive
special rules. (This showed bugs in the strip steps in the
standard rules. The wrong strip flag was also used for *.po
here.)
Removed some ${ECHO}s and `@'s. Normal make echoing of what is
being done is now not much more verbose than the echo messages
were, and is more useful.
Fixed back to front -X and -x strip flags in .m.o and .m.po rules.
Fixed disordered .m.o and .m.po rules. What is .m?
Stripping probably should be removed. It makes problems in library
functions hard to debug...
