9debe21353 - Handle mixer read ioctls correctly. They have the same group, number and
argument size as their write counterparts and were handled as write ioctls.
- Emulate some cdrom ioctls.

5206bca10a Enable vmspace sharing on SMP. Major changes are,
- %fs register is added to trapframe and saved/restored upon kernel entry/exit.
- Per-cpu pages are no longer mapped at the same virtual address.
- Each cpu now has a separate gdt selector table. A new segment selector
  is added to point to per-cpu pages, per-cpu global variables are now
  accessed through this new selector (%fs). The selectors in gdt table are
  rearranged for cache line optimization.
- fask_vfork is now on as default for both UP and SMP.
- Some aio code cleanup.

2267af789e Add (but don't activate) code for a special VM option to make
downward growing stacks more general.
Add (but don't activate) code to use the new stack facility
when running threads, (specifically the linux threads support).
This allows people to use both linux compiled linuxthreads, and also the
native FreeBSD linux-threads port.

The code is conditional on VM_STACK. Not using this will
produce the old heavily tested system.

4c56fcdead Removed the cast to a pointer in the definition of PS_STRINGS and
adjusted related casts to match (only in the kernel in this commit).
The pointer was only wanted in one place in kern_exec.c.  Applications
should use the kern.ps_strings sysctl instead of PS_STRINGS, so they
shouldn't notice this change.

aa855a598d *gulp*. Jordan specifically OK'ed this..
This is the bulk of the support for doing kld modules.  Two linker_sets
were replaced by SYSINIT()'s.  VFS's and exec handlers are self registered.
kld is now a superset of lkm.  I have converted most of them, they will
follow as a seperate commit as samples.
This all still works as a static a.out kernel using LKM's.

514058dc0d Unregister the glibc2 brand at module unload time.
Change the ELF registration/unregistration scheme to be less error prone.
Adding a new brand requires a single addition to linux_brandlist instead of
modifying linux_load(), linux_unload(), and linux_elf_init().

22d4b0fb41 Add provisions for variant core dump file formats, depending on the
object format of the executable being dumped.  This is the first
step toward producing ELF core dumps in the proper format.  I will
commit the code to generate the ELF core dumps Real Soon Now.  In
the meantime, ELF executables won't dump core at all.  That is
probably no less useful than dumping a.out-style core dumps as they
have done until now.

2394cd9adb Initial support for using linux X servers under emulation - to use an
XFree86 server, users need to create the following links in their
/compat/linux/dev directory (assuming kernel configured with 4 VTs).

lrwxrwxrwx  1 root  wheel  7 Aug 30 22:59 tty0 -> console
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty1 -> ttyv0
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty2 -> ttyv1

lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty4 -> ttyv3

VT switching is still not yet supported. Attempting to switch VT
currently will cause Xserver bus error.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.
