ad925439e0 Device megapatch 4/6:
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

df397dedea Device megapatch 1/6:
Free approx 86 major numbers with a mostly automatically generated patch.

A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.

783ae539c3 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

0ae911eb0e Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

541937cf73 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

f10fa038c1 With this commit, I hereby pronounce gensetdefs past its use-by date.
Replace the a.out emulation of 'struct linker_set' with something
a little more flexible.  <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set.  They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>).  Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated.  This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.

663cbe4fc2 Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

4f4eb0cfe5 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.
  PR: kern/10113
  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.

  SC_DFLT_FONT
  makeoptions "SC_DFLT_FONT=_font_name_"
  Include the named font as the default font of syscons.  16-line,
  14-line and 8-line font data will be compiled in.  This option replaces
  the existing STD8X16FONT option, which loads 16-line font data only.

- 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.
  PR: i386/7510
  Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx.

- 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.

6a5dc97620 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

Reformat and initialize correctly all "struct cdevsw".

        Initialize the d_maj and d_bmaj fields.

I used a program to do most of this, so all the files now use the
same consistent format.  Please keep it that way.
