288078be0f Translate T_PROTFLT to SIGSEGV instead of SIGBUS when running under
Linux emulation.  This make Allegro Common Lisp 4.3 work under
FreeBSD!

c8a7999933 Update the ELF image activator to use some of the exec resources rather
than rolling it's own.  This means that it now uses the "safe"
exec_map_first_page() to get the ld.so headers rather than risking a panic
on a page fault failure (eg: NFS server goes down).
Since all the ELF tools go to a lot of trouble to make sure everything
lives in the first page for executables, this is a win.  I have not seen
any ELF executable on any system where all the headers didn't fit in the
first page with lots of room to spare.
I have been running variations of this code for some time on my pure ELF
systems.

1560a9d538 We were (I think) missing a vrele() on the vnode for the object loaded
via PT_INTERP (usually /usr/libexec/ld-elf.so.1).

5856e12e69 Fully implement vfork. Vfork is now much much faster than even our
fork. (On my machine, fork is about 240usecs, vfork is 78usecs.)

Implement rfork(!RFPROC !RFMEM), which allows a thread to divorce its memory
	from the other threads of a group.

Implement rfork(!RFPROC RFCFDG), which closes all file descriptors, eliminating
	possible existing shares with other threads/processes.

Implement rfork(!RFPROC RFFDG), which divorces the file descriptors for a
	thread from the rest of the group.

Fix the case where a thread does an exec.  It is almost nonsense for a thread
	to modify the other threads address space by an exec, so we
	now automatically divorce the address space before modifying it.

d8a4f230d5 Use OID_AUTO instead of magic number for old sysctl debug.elf_trace. The
magic number conflicted with the one for the Lite2 sysctl debug.busyprt.

Staticized some variables.

Removed unused #includes.

3ac4d1ef0c Don't #include <sys/fcntl.h> in <sys/file.h> if KERNEL is defined.
Fixed everything that depended on getting fcntl.h stuff from the wrong
place.  Most things don't depend on file.h stuff at all.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

250c11f9c3 Tweak the data/bss segment page count. The last version worked
with all the test cases I tried, I'm sure this is more correct.

Tweak some prototypes.

8191d577aa Fix some rounding problems.. In some (fairly rare) situtaions it mapped
one page too many, which caused obreak() to fail in vm_map_find() with
ENOMEM because of the conflicting page.

e1743d02cd First attempt at FreeBSD & Linux ELF support.
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.
(No it won't run quake yet :)
