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
