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

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...
large enough to contain the ethernet header. There appears to be a
condition where the card can return "0" in some failure cases, and this
causes bad things to happen (a panic).
and they broke when yacc started generating `#include <stdlib.h>', but
the breakage was hidden by compatibility cruft in gcc unless DESTDIR
was unusual.
have successfully built, booted, and run a number of different ELF
kernel configurations, including GENERIC. LINT also builds and
links cleanly, though I have not tried to boot it.
The impact on developers is virtually nil, except for two things.
All linker sets that might possibly be present in the kernel must be
listed in "sys/i386/i386/setdefs.h". And all C symbols that are
also referenced from assembly language code must be listed in
"sys/i386/include/asnames.h". It so happens that failure to do
these things will have no impact on the a.out kernel. But it will
break the build of the ELF kernel.
The ELF bootloader works, but it is not ready to commit quite yet.
really far too long. Let us try 100ms instead, if you have a PP200,
maybe that's even too long. This should speed up make -j# builds.
I wonder why SIGCHLD isn't used...
UN_ULOCK flag. This shows a locking violation but I couldn't find the
reason UN_ULOCK is not set or upper vnode is not unlocked. I added
the code that detect this case and adjust un_flags. DIAGNOSTIC kernel
doesn't adjust un_flags, but just panic here to help debug by kernel
hackers.
delay after we reset the card to allow the card to come back to life.
It appears the newer card takes longer to reset.
