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.

It appears the newer card takes longer to reset.

The man page warns against using this command when your
timeout value is slightly more than the other sides :{}

type mismatches. There was no problem in practice (at least on 386's).
The timeout args still get bogusly cast from int to `void *' via
caddr_t and back to int.
type mismatches. mcd and scd were/are particularly bogus. They
used a general purpose function taking 2 args for the timeout
function and fudged varargs stuff to supply the second arg for the
timeout case. This broke `cc -mrtd'. Bounce through a timeout
function instead. The timeout arg still gets bogusly cast from
int to `void *' and back.
difference of approx 3mins in make world on my P6!!! This means
that vfork now has full address space sharing, so beware with
sloppy vfork programming. Also, you really do need to apply
the previously committed popen fix in libc.
type mismatches. There was no problem in practice (at least on 386's).
Don't cast NULL in calls to timeout functions. pcvt is fully prototyped
and doesn't support K&R.
Timeout functions take args of type `void *', so use magic numbers of
type `void *' for UPDATE_* to reduce the danger of wrong conversions.
Removed FreeBSD-pre-1.1-related TIMEOUT_FUNC_T macro. It was especially
bogus for the pre-1.1 case.
type mismatches. There was no problem in practice (at least on 386's).
Removed NetBSD-related TIMEOUT macro. NetBSD uses the same BSD4.4Lite
timeout interface as FreeBSD. As a concession to portability, declare
the timeout function without using the FreeBSD timeout_t typedef.
the (buggy) support for alternative entry points. ALTENTRY() was only
used for memmove(). Optimizing for space was particularly silly because
memcpy() is rarely used (gcc normally inlines it).

- use a slightly less bogus copyright. This file was never contributed
to Berkeley. It still claims to be copright by the Regents.
- use <machine/asm.h> instead of "DEFS.h".
- use RCSID($Id$) instead of explicit assembly code and messy ifdefs.
The rcsid won't be put into the object file until we make RCSID()
non-null. NetBSD uses a LIBC_SCCS ifdef here. We used a LIBC_RCS
instead, but I want RCSID() to be controlled directly by LIBC_RCS
(actually by LIB_RCS). This is the only difference with the NetBSD
version.
- added ifdefs to support generation of memcpy() and memmove(). The
other changes are "while I'm here" to get this.
- improved style of the copy backwards case.
properly. Simply don't use the gcc macros if we're not gcc, and
declare prototypes for the byte-swapping functions in case the
macro versions are not used. The previous fix was wrong and broke
libpcap, which abuses -Dlint.
Don't pollute the namespace if _POSIX_SOURCE is defined. This is
broken - it makes almost everything in <machine/endian.h> inaccessible
if _POSIX_SOURCE is defined, yet <machine/endian.h> is not a POSIX
header. Other systems don't do it any better.
Removed always-false `BYTE_ORDER == BIG_ENDIAN' ifdef.

2. pccard.c: PCIC_RESUME_RESET is now (also) a sysctl. (Never make it
a #ifdef if it can be made a sysctl!)
3. pcic.c: make getb() and putb() proper member functions of struct
pcic_slot. Add a couple of missing casts.
for how to use gcc to invoke the linker only.
Removed `.if 0'ed support for not creating intermediate object files.
Removed unused include of bsd.libnames.mk (LDONLY had the last reference
to it).
Removed stale misplaced comment about MANDEPEND.
wind up writing zeros instead of real data when the file is on an NFSv2
mounted directory.
While tracking this bug down, I noticed that nfs_asyncio was waking *all*
the iods when a block was written instead of just one per block. Fixing this
gives a 25% performance improvment for writes on v2 (less for v3).
Both are 2.2 candidates.
