d3cc2bd29e Initial attempt at getting Linux QMAGIC shared lib support. I have
successfully run linux netscape 2.0b3 with a QMAGIC ld.so and libc/libm
that I found on some linux machine that I _think_ is running slackware 3.0.

There are still problems..  ld.so claims the libraries are the wrong
format, but it still runs anyway.. :-/  The QMAGIC ld.so also screams
about needing ld.so.cache, and running a linux ldconfig is quite
educational.  You soon learn to run "chroot /compat/linux /bin/ldconfig"
where ldconfig is living in /compat/linux/bin. :-]

(Lets just say that it puts loads of symlinks in /usr/lib otherwise :-)

ef04503da8 Clean up some warnings by using the generated structures in <sys/sysproto.h>
for passing to the bsd system calls, rather than inveninting our own
equivalent structures.

ac9a8f2f81 Attempt to make the Linux LKM compile again after the recent VM include
de-nesting changes...
(I figured this might be usefulif it actually built, since I've told
 everybody to rebuild it or die.. :-)

b3728b2483 Update the Linux LKM to use the new ps_strings and stack gap arrangements.
(note you should recompile the linux and ibcs2 lkms after this)

d973c0554a Include <vm/vm.h> explicitly to avoid breaking when vnode_if.h doesn't
include vm stuff.

1f3dad5a8d Completed function declarations and added prototypes.
Removed some unnecessary #includes.

Fixed warnings about nested externs.

c52007c2cc All:
Changed vnodep -> vp for consistency with the rest of the kernel, and
changed iparams -> imgp for brevity.

kern_exec.c:
   Explicitly initialized some additional parts of the image_params struct
to avoid bzeroing it. Rewrote the set-id code to reduce the number of
logical tests. The rewrite exposed a mostly benign bug in the algorithm:
traced set-id images would get ktracing disabled even if the set-id didn't
happen for other reasons.

d39fe2ffaf Fix the getdirentries of ibcs2 to handle uneven DIRBLKSIZ offsets.
Slight modification from previous fix.

Also, fix problem where an entry would be skipped next call if not enough room
in buffer current call.

Obtained from: other people on the net ?

1. stepping over syscalls (gdb ni) sends you to DDB, and returned
to the wrong address afterwards, with or without DDB.  patch in
i386/i386/trap.c below.

2. the linux emulator (modload'ed) still causes panics with DIAGNOSTIC,
re-applied a patch posted to one of the lists...

2b14f991e6 Reviewed by: julian with quick glances by bruce and others
Submitted by:	terry (terry lambert)
This is  a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.

fe89a532f1 Modified linux_readdir() function to properly handle Linux readdir()
calls with a byte size of 1.  This special case was not
correctly emulated.  Now programs such as a simple 'ls' to a commercial
Macintosh emulator called 'executor' will work correctly.

c0e5de7d88 Moved setting of VTEXT flag into the appropriate image activators. This
fixes a bug where linux binaries would get the flag set inappropriately.

c21dee177f First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).

Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.

Kernel must be compiled with "options COMPAT_LINUX" for this to work.
