to declare things on your own!

This implements the mmu stuff for the mmuless cpus - a lot of it stubs
to avoid ifdefs in core code

Basically a nop for MMU based systems

Primarily adds Nvidia + some i845G

Add Zwane
Remove soundmodem stuff
Update snapgear

 "Well, I have another solution, which doesn't need additional Makefile
  magic or anything.

  I just put the module name into each .o file where <linux/module.h> is
  included. Putting it into the section .gnu.linkonce.modname has the effect
  that even for multi-part modules, we only end up with one copy of the
  name.

  Caveat: I'm using the preprocessor macro KBUILD_MODNAME to know what to
  put into .gnu.linkonce.modname. The following used to happen:

  (drivers/isdn/eicon/Makefile)

  divas-objs := common.o Divas_mod.o ...
  eicon-objs := common.o eicon_mod.o ...

  Divas_mod.o is compiled with -DKBUILD_MODNAME=divas
  eicon_mod.o is compiled with -DKBUILD_MODNAME=eicon
  common.o is compiled with -DKBUILD_MODNAME=divas_eicon

  So in the case above, both divas.o and eicon.o would end up with
  a .gnu.linkonce.modname section containing "divas_eicon"

  My fix to this is to not define KBUILD_MODNAME when compiling an object
  whilch will be linked into more than one module - so common.o gets no
  .gnu.linkonce.modname section at all. Works fine here.

  Now, doing this I remove one of the reasons why we would need modules
  linked as '.ko' ;), but it seems much cleaner than generating a temporary
  file, using objcopy etc."

On the v850, the elf toolchain uses a `_' prefix for all user symbols
(I'm not sure why, since most toolchains seem to have dropped this sort
of thing).

The attached patch adds the ability to deal with this, if the macro
MODULE_SYMBOL_PREFIX is defined by <asm/module.h>.  This only affects
places where symbol names come from the user, e.g., EXPORT_SYMBOL, or
the explicit symbol-names used in kernel/module.c itself.

[Tweaked a little by Rusty, original by Miles Bader]

This patch allows the new depmod to generate the USB & PCI hotplug
tables.  Greg Banks and I are (slowly) working on a better solution, but
allows the old-style "modules.pcimap" etc.  to be generated in the short
term.

This patch adds a "__mod_XXX_table" symbol which is an alias to the
module table, rather than a pointer.  This makes it relatively trivial
to extract the table.  Previously, it required a pointer dereference,
which means the relocations must be applied, which is why the old depmod
needs so much of modutils (ie.  it basically links the whole module in
order to find the table).

The old depmod can still be invoked using "-F System.map" to generate
the tables (there'll be lots of other warnings, and it will generate a
completely bogus modules.dep, but the tables should be OK.)

Two fixes.  Firstly, set ALLOC on the right section so we actually
keep the symbol names and don't deref a freed section, and secondly
get the symbol size (more) correct.

Currently, uart_get_divisor() and uart_get_baud_rate() take a tty
structure.  We really want them to take a termios structure so we
can avoid passing a tty structure all  the way down to the low level
drivers.

In order to do this, we need to be able to convert a termios
structure to a numeric baud rate - we provide tty_termios_baud_rate() in
tty_io.c for this purpose.  It performs a subset of the
tty_get_baud_rate() functionality, but without any "alt_speed"
kludge.

We finally export uart_get_baud_rate() and uart_get_divisor() to for
low level drivers to use.  We now have all the functions in place
to support ports which want to have access to the real baud rate
rather than a divisor value.

uart_get_divisor() calculates the divisor for standard uarts, and
will eventually become a helper function for low level port drivers.

This is another step towards moving the divisor calculations into
the low level drivers, thereby allowing the faster baud rates
mentioned in the previous cset.  Moving this field to uart_port
means that the low level drivers do not have to know about the
uart_state structure.

We provide a new function, uart_get_baud_rate(), to return the
desired numeric baud rate from the uart_port and tty structures.
This allows us to:

1. localise the 38400 alternate speed kludge to one area.
2. support faster baud rates than the usual baud_base / desired_rate
   calculations in the future (eventually allowing the use of the
   magic divisors in 8250.c.)

We originally checked for failure by checking if the returned code
was non-zero.  Strictly, it should be a negative value.

Patch from Randolph Chung, slightly modified by rmk.

When displaying the details of memory mapped serial ports, we want to show
some sane base value.  The cookie returned from ioremap can be meaningless
to users (and developers), especially when the cookie could be a dynamically
allocated virtual address.

The more useful cookie is the value passed into ioremap.  We already have
support for handling this cookie internally - we haven't allowed the PCI
probe module to hand it to the higher levels until now.

Patch from Zwane Mwaikambo, fixed by rmk, comments by rmk.

SIIG cards have parallel ports in addition to serial ports.  We therefore
probe the cards in parport_serial.c and call the serial specific probe
functions in 8250_pci.c

This is the second half of a patch that was applied in 2.5.50 to
parport_serial by others without the corresponding 8250_pci.c changes.

During initialisation of 8250 serial, we scan a list of ISA ports and
register any ports.  We then perform PNPBIOS scanning, which re-registers
ttyS0.  Unfortunately, if devfs is enabled, devfs reports an error because
we try to create two tts/0 entries.

Therefore, when adding a new port we check that it has not been detected
before attempting to probe the port and register it with devfs (via the
tty layer.)

Currently scsi_register_host silently fixes up missing initializations
of max_sectors and release.  Add some printks complaining about this
so we can get rid of it sooner or later.

The same for sr (I didn't actually had a chance to actually test this,
but it's the same change as in sd).

This is the final patch to make sd work properly in a hotplug
enviroment.  Add a bitmap for currently used disks so that we
can properly reuse dev_t when a disk is hot-unplugged.

While at that add support for the eight additional majors
allocated to sd in the latest devices.txt [1].

If only register_blkdev finally died we could nuke almost all
knowledge of majors/minors from sd...

[1] http://www.lanana.org/docs/device-list/devices.txt

(1) move all bdev methods in one place instead of spreading them all
    around the file
(2) consistant naming: everything is sd_<operation> now
(3) use scsi_device_get/scsi_device_put
(4) remove bogus checks scsi_disk->device set, since 2.5.4x it always is
(5) clean up some coding style issues
