This shrinks the size of "struct i2c_client" by 40 bytes:
- Substantially shrinks the string used to identify the chip type
- The "flags" don't need to be so big
- Removes some internal padding
It also adds kerneldoc for that struct, explaining how "name" is really a
chip type identifier; it's otherwise potentially confusing.
Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name
and for i2c_adapter.name, this needed to affect i2c_adapter too. The
adapters which used that symbol now use the more-obviously-correct
idiom of taking the size of that field.
JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to
avoid wasting space in padding.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

IDs have been defined but not used by most of the I2C adapters.
By having a unique ID, clients can check for correct connection
during probe.

Summary of changes:
- fixes:
o legacy I/O region size is 64 bytes, not 8 bytes
- general cleanup:
o removed code for the unsupported I2C block data, block data,
proc call and block proc call transfer modes
o removed detail warnings about unsupported modes that are
covered in a general warning (unsupported transaction...)
anyway
o removed necessity of a definition of struct i2c_adapter
o moved definition of struct i2c_algorithm, making forward
declarations of nforce2_access and nforce2_func unnecessary
- minor changes:
o in the description mention the nForce 5xx chipsets
o changes my e-mail address in MODULE_AUTHOR
Theses cleanups shrink the driver binary size from 4.0 kB to 2.7 kB
on i386.

Add support for the new nForce4 MCP51 (also known as nForce 410 or
430) and nForce4 MCP55 to the i2c-nforce2 driver. Some code changes
were required because the base I/O address registers have changed in
these versions. Standard BARs are now being used, while the original
nForce2 chips used non-standard ones.

Clean up name string usage in 12 i2c bus drivers:
* Use the i2c_adapter name for requesting the I/O region rather than
redefining a new string.
* Do not initialize the i2c_adapter name to "unset".
This should save a few data bytes here and there.

attached is a small patch that removes unused code from i2c-nforce2 and
adds a single debug message. The patch is against 2.6.13-rc3-mm1.
I have tested the patch with 2.6.13-rc3: compiles cleanly and works as
without the patch (as expected).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
