Merge branch 'Space-cleanup' 

Arnd Bergmann says:

====================
drivers/net/Space.c cleanup

I discovered that there are still a couple of drivers that rely on
beiong statically initialized from drivers/net/Space.c the way
we did in the last century. As it turns out, there are a couple
of simplifications that can be made here, as well as some minor
bugfixes.

There are four classes of drivers that use this:

- most 10mbit ISA bus ethernet drivers (and one 100mbit one)
- both ISA localtalk drivers
- several m68k ethernet drivers
- one obsolete WAN driver

I found that the drivers using in arch/m68k/ don't actually benefit
from being probed this way as they do not rely on the netdev= command
line arguments, they have simply never been changed to work like a
modern driver.

I had previously sent a patch to remove the sbni/granch driver, and
there were no objections to this patch but forgot to resend it after
some discussion about another patch in the same series.

For the ISA drivers, there is usually no way to probe multiple devices
at boot time other than the netdev= arguments, so all that logic is left
in place for the moment, but centralized in a single file that only gets
included in the kernel build if one or more of the drivers are built-in.

I'm also changing the old-style init_module() functions in these drivers
to static functions with a module_init() annotation, to more closely
resemble modern drivers. These are the last drivers in the kernel to
still use init_module/cleanup_module, removing those may enable future
cleanups to the module loading process.

       Arnd

Changes in v2:

- replace xsurf100 change with Michael's version
- make it PATCH instead of RFC
- rebase to net-next as of August 3

/* sbni.c: Granch SBNI12 leased line adapters driver for linux
*
* Written 2001 by Denis I.Timofeev (timofeev@granch.ru)
*
* Previous versions were written by Yaroslav Polyakov,
* Alexey Zverev and Max Khon.
*
* Driver supports SBNI12-02,-04,-05,-10,-11 cards, single and
* double-channel, PCI and ISA modifications.
* More info and useful utilities to work with SBNI12 cards you can find
* at http://www.granch.com (English) or http://www.granch.ru (Russian)
*
* This software may be used and distributed according to the terms
* of the GNU General Public License.
*
*
* 5.0.1 Jun 22 2001
* - Fixed bug in probe
* 5.0.0 Jun 06 2001
* - Driver was completely redesigned by Denis I.Timofeev,
* - now PCI/Dual, ISA/Dual (with single interrupt line) models are
* - supported
* 3.3.0 Thu Feb 24 21:30:28 NOVT 2000
* - PCI cards support
* 3.2.0 Mon Dec 13 22:26:53 NOVT 1999
* - Completely rebuilt all the packet storage system
* - to work in Ethernet-like style.
* 3.1.1 just fixed some bugs (5 aug 1999)
* 3.1.0 added balancing feature (26 apr 1999)
* 3.0.1 just fixed some bugs (14 apr 1999).
* 3.0.0 Initial Revision, Yaroslav Polyakov (24 Feb 1999)
* - added pre-calculation for CRC, fixed bug with "len-2" frames,
* - removed outbound fragmentation (MTU=1000), written CRC-calculation
* - on asm, added work with hard_headers and now we have our own cache
* - for them, optionally supported word-interchange on some chipsets,
*
* Known problem: this driver wasn't tested on multiprocessor machine.
