264c3d8738 Undo my previous commit and do it differently. Break the ffs() etc macros
into two parts - one to do the bsfl and the other to convert the result
(base 0) to ffs()-like (base 1) in inline C.  This enables the optimizer
to be a lot smarter in certain cases, like where it knows that the argument
is non-zero and we want ffs(known non zero arg) - 1.  This appears to
produce identical code to the old inline when the argument is unknown.

08c40841d8 Create callable (non-inline) versions of the atomic_OP_TYPE functions
that are linked into the kernel.  The KLD compilation options are
changed to call these functions, rather than in-lining the
atomic operations.

This approach makes atomic operations from KLDs significantly
faster on UP systems (though somewhat slower on SMP systems).

7880e8b2d5 Mindbogglingly, many BIOS vendors expect to be able to load %ds with
0x40 and then access data stored in real-mode segment 0x40, even when
called in protected mode.  Microsoft unfortunately coddle these individuals,
and so must we if we want to run their code.

a7674320e9 On FPU exceptions, pass a useful error code (one of the FPE_...
macros) to the signal handler, for old-style BSD signal handlers as
the second (int) argument, for SA_SIGINFO signal handlers as
siginfo_t->si_code. This is source-compatible with Solaris, except
that we have no <siginfo.h> (which isn't even mentioned in POSIX
1003.1b).

An rather complete example program is at
  http://www3.cons.org/cracauer/freebsd-signal.c
This will be added to the regression tests in src/.

This commit also adds code to disable the (hardware) FPU from
userconfig, so that you can use a software FP emulator on a machine
that has hardware floating point. See LINT.

91fe3dc1e1 Implement an all-CPU shootdown-style rendezvous facility. This allows
the caller to specify a function to be guarded between an entry and exit
barrier, as well as pre- and post-barrier functions.

The primary use for this function is synchronised update of per-cpu private
data.  The implementation is almost (but not quite) MI; with a better
mechanism for masking per-CPU interrupts it could probably be hoisted.

aff66c5455 Implement SA_SIGINFO for i386. Thanks to Bruce Evans for much more
than a review, this was a nice puzzle.

This is supposed to be binary and source compatible with older
applications that access the old FreeBSD-style three arguments to a
signal handler.

Except those applications that access hidden signal handler arguments
bejond the documented third one. If you have applications that do,
please let me know so that we take the opportunity to provide the
functionality they need in a documented manner.

Also except application that use 'struct sigframe' directly. You need
to recompile gdb and doscmd. `make world` is recommended.

Example program that demonstrates how SA_SIGINFO and old-style FreeBSD
handlers (with their three args) may be used in the same process is at
http://www3.cons.org/tmp/fbsd-siginfo.c

Programs that use the old FreeBSD-style three arguments are easy to
change to SA_SIGINFO (although they don't need to, since the old style
will still work):

  Old args to signal handler:
    void handler_sn(int sig, int code, struct sigcontext *scp)

  New args:
    void handler_si(int sig, siginfo_t *si, void *third)
  where:
    old:code == new:second->si_code
    old:scp == &(new:si->si_scp)     /* Passed by value! */

The latter is also pointed to by new:third, but accessing via
si->si_scp is preferred because it is type-save.

FreeBSD implementation notes:
- This is just the framework to make the interface POSIX compatible.
  For now, no additional functionality is provided. This is supposed
  to happen now, starting with floating point values.
- We don't use 'sigcontext_t.si_value' for now (POSIX meant it for
  realtime-related values).
- Documentation will be updated when new functionality is added and
  the exact arguments passed are determined. The comments in
  sys/signal.h are meant to be useful.

279f2101e7 Improve compatibility with other systems by changing the default
behavior slightly.

If machine/bus.h is included, but neither bus_memio.h nor bus_pio.h
are included, then behave as if both were included.

This won't change existing drivers, all of which include one or more
of bus_{p,mem}io.h, but will allow drivers from other systems to come
over with fewer changes.  I freely admit that this might not be
optimal for some drivers, but those drivers can be optimized for
FreeBSD after the initial bringup happens.

Without the change, there is a bug that preclude drivers from
compiling with strange warning/errors.

I've been running this here for a while now w/o ill effects.

6e8394b8ba The second phase of syscons reorganization.
- Split syscons source code into manageable chunks and reorganize
  some of complicated functions.

- Many static variables are moved to the softc structure.

- Added a new key function, PREV.  When this key is pressed, the vty
  immediately before the current vty will become foreground.  Analogue
  to PREV, which is usually assigned to the PrntScrn key.

  Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de>

- Modified the kernel console input function sccngetc() so that it
  handles function keys properly.

- Reorganized the screen update routine.

- VT switching code is reorganized.  It now should be slightly more
  robust than before.

- Added the DEVICE_RESUME function so that syscons no longer hooks the
  APM resume event directly.

- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
  SC_NO_HISTORY and SC_NO_SYSMOUSE.
  Various parts of syscons can be omitted so that the kernel size is
  reduced.

  SC_PIXEL_MODE
  Made the VESA 800x600 mode an option, rather than a standard part of
  syscons.

  SC_DISABLE_DDBKEY
  Disables the `debug' key combination.

  SC_ALT_MOUSE_IMAGE
  Inverse the character cell at the mouse cursor position in the text
  console, rather than drawing an arrow on the screen.

  14-line and 8-line font data will be compiled in.  This option replaces

- The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c.

- The video driver provides a set of ioctl commands to manipulate the
  frame buffer.

- New kernel configuration option: VGA_WIDTH90
  Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60.  These
  modes are mot always supported by the video card.

- The header file machine/console.h is reorganized; its contents is now
  split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h
  (another new file).  machine/console.h is still maintained for
  compatibility reasons.

- Kernel console selection/installation routines are fixed and
  slightly rebumped so that it should now be possible to switch between
  the interanl kernel console (sc or vt) and a remote kernel console
  (sio) again, as it was in 2.x, 3.0 and 3.1.

- Screen savers and splash screen decoders
  Because of the header file reorganization described above, screen
  savers and splash screen decoders are slightly modified.  After this
  update, /sys/modules/syscons/saver.h is no longer necessary and is
  removed.

50045fbc7c Changed the global `idt' from an array to a pointer so that npx.c
automatically hacks on the active copy of the IDT if f00f_hack()
has changed it.  This also allows simplifications in setidt().
This fixes breakage of FP exception handling by rev.1.55 of
sys/kernel.h.  FP exceptions were sent to npx.c's probe handlers
because npx.c "restored" the old handlers to the wrong copy of the
IDT.  The SYSINIT for f00f_hack() was purposely run quite late to
avoid problems like this, but it is bogusly associated with the
SYSINIT for proc0 so it was moved with the latter.

31a08ab08e Add device driver support for the Lucent WaveLAN/IEEE 802.11 PCMCIA
adapter (and some workalikes). Also add man pages and a wicontrol
utility to manipulate some of the card parameters.

This driver was written using information gleaned from the Lucent HCF Light
library, though it does not use any of the HCF Light code itself, mainly
because it's contaminated by the GPL (but also because it's pretty gross).
The HCF Light lacks certain featurs from the full (but proprietary) HCF
library, including 802.11 frame encapsulation support, however it has
just enough register information about the Hermes chip to allow someone
with enough spare time and energy to implement a proper driver. (I would
have prefered getting my hands on the Hermes manual, but that's proprietary
too. For those who are wondering, the Linux driver uses the proprietary
HCF library, but it's provided in object code form only.)

Note that I do not have access to a WavePOINT access point, so I have
only been able to test ad-hoc mode. The wicontrol utility can turn on
BSS mode, but I don't know for certain that the NIC will associate with
an access point correctly. Testers are encouraged to send their results
to me so that I can find out if I screwed up or not.
