Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.
To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.
The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.

aic7xxx.c:
Fix the reset code.
Instead of queing up all of the SCBs that timeout during timeout
processing, we take the first and have it champion the effort.
Any other scbs that timeout during timeout handling are given
another lifetime to complete in the hopes that once timeout
handing is finished, they will complete normally. If one of
these SCBs times out a second time, we panic and Justin tries
again.
The other major change is to queue flag aborted SCBs during timeout
handling, and "ahc_done" them all at once as soon as we have the
controller back into a sane state. Calling ahc_done any earlier
will cause the SCSI subsystem to toss the command right back at
us and the attempt to queue the command will conflict with what
the timeout routine is trying to accomplish.
The aic7xxx driver will now respond to bus resets initiated by
other devices.

netscape-2.0 for Linux running all the Java stuff. The scrollbars are now
working, at least on my machine. (whew! :-)
I'm uncomfortable with the size of this commit, but it's too
inter-dependant to easily seperate out.
The main changes:
COMPAT_LINUX is *GONE*. Most of the code has been moved out of the i386
machine dependent section into the linux emulator itself. The int 0x80
syscall code was almost identical to the lcall 7,0 code and a minor tweak
allows them to both be used with the same C code. All kernels can now
just modload the lkm and it'll DTRT without having to rebuild the kernel
first. Like IBCS2, you can statically compile it in with "options LINUX".
A pile of new syscalls implemented, including getdents(), llseek(),
readv(), writev(), msync(), personality(). The Linux-ELF libraries want
to use some of these.
linux_select() now obeys Linux semantics, ie: returns the time remaining
of the timeout value rather than leaving it the original value.
Quite a few bugs removed, including incorrect arguments being used in
syscalls.. eg: mixups between passing the sigset as an int, vs passing
it as a pointer and doing a copyin(), missing return values, unhandled
cases, SIOC* ioctls, etc.
The build for the code has changed. i386/conf/files now knows how
to build linux_genassym and generate linux_assym.h on the fly.
Supporting changes elsewhere in the kernel:
The user-mode signal trampoline has moved from the U area to immediately
below the top of the stack (below PS_STRINGS). This allows the different
binary emulations to have their own signal trampoline code (which gets rid
of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so
that the emulator can provide the exact "struct sigcontext *" argument to
the program's signal handlers.
The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which
have the same values as the re-used SA_DISABLE and SA_ONSTACK which are
intended for sigaction only. This enables the support of a SA_RESETHAND
flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal
semantics where the signal handler is reset when it's triggered.
makesyscalls.sh no longer appends the struct sysentvec on the end of the
generated init_sysent.c code. It's a lot saner to have it in a seperate
file rather than trying to update the structure inside the awk script. :-)
At exec time, the dozen bytes or so of signal trampoline code are copied
to the top of the user's stack, rather than obtaining the trampoline code
the old way by getting a clone of the parent's user area. This allows
Linux and native binaries to freely exec each other without getting
trampolines mixed up.

- split driver into FreeBSD specific and camera specific portions
(qcamio.c can run in user mode, with a Linux "driver top" etc,
and qcam.c should be trivial to port to NetBSD and BSDI.)
- support for 4bppand bidirectional transfers working better
- start of interleaved data-transfers byte-stream decodes (some of this
stuff has been pulled out for the moment to make it easier to debug)
At this point, anyone who wants to port it to other platforms should feel
free to do so. Please feed changes directly back to me so that I can produce
a unified distribution.

Most of the work was in spliting out common portions of the driver and
making them generic enough to be called from the eisaconf probe.

eisaconf.c:

in the eisa_add* functions since eisa_registerdev has already been
called and we have a kdc to manipulate.

Rules have numbers used for ordering and deletion.
Remove "rerorder" code entirely.
Count packet & bytecount matches for rules.
Code in -current & -stable is now the same.
- Optimise the linux a.out loading and uselib system calls so they
take advantage of some of John's recent interface improvements.
Basically, this means they make far less map changes than before.
- Attempt to plug some potentially nasty kernel_map memory leaks..
- Improve support for QMAGIC libs (I only use QMAGIC (ie: a.out libraries from
the slackware 3.0 dist) but this depends on other changes to enhance
the /compat/linux support)
- uselib goes out through a single exit as part of the resource tracking
that I did when closing the resource leaks on errors. This could be
cleaner than what I did, but making a 30-deep nested if/else was not my
idea of fun, neither did I want to repeat the same code 30 times over for
each failure possibility. I guess this function needs to be split into
smaller functions to solve this.
I've been running the Linux Netscape-2.0 (with Java) to test this, and apart
from the long-standing problem with the missing scrollbars, it appears to
still work as before with ZMAGIC libs (and the leaks).. However, I've
been using it with mods for the signal trampoline code for native linux stack
frames on signals and exterminated the blasted sigreturn printf() problem,
so I can't be certain that there is not a dependency on something else.
