Convert static struct pci_device_id *[] to static DEFINE_PCI_DEVICE_TABLE
tables.
Use DEFINE_PCI_DEVICE_TABLE ensures we make the pci_device_id table const
and marked as __devinitconst.
This also fixes some warnings from checkpatch:
e.g.
WARNING: Use DEFINE_PCI_DEVICE_TABLE for struct pci_device_id

The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make initialization data also constant.
The semantic match that finds this kind of pattern is as follows:

When an ACPI resource conflict is detected, error messages are already
printed by ACPI. There's no point in causing the driver core to print
more error messages, so return one of the error codes for which no
message is printed.
This fixes bug #14293:

Only accept dynids whose driver_data value matches one of the driver's
pci_driver_id entries. This prevents the user from accidentally passing

The driver flag dynids.use_driver_data is almost consistently not set,
and causes more problems than it solves. It was initially intended as a
flag to indicate whether a driver's usage of driver_data had been
carefully inspected and was ready for values from userspace. That audit
was never done, so most drivers just get a 0 for driver_data when new
IDs are added from userspace via sysfs. So remove the flag, allowing
drivers to see the data directly (a followon patch validates the passed
driver_data value against what the drivers expect).

Check for ACPI resource conflicts in i2c bus drivers. I've included
all recent SMBus master drivers for PC hardware.
I've voluntarily left out:
* Drivers that don't run on PCs: they can't conflict with ACPI.
* Bit-banged bus device drivers: it's very unlikely that ACPI would
deal with such buses.

Let general purpose I2C/SMBus bus drivers add SPD to their class. Once
this is done, we will be able to tell the eeprom driver to only probe
for SPD EEPROMs and similar on these buses.
Note that I took a conservative approach here, adding I2C_CLASS_SPD to
many drivers that have no idea whether they can host SPD EEPROMs or not.
This is to make sure that the eeprom driver doesn't stop probing buses
where SPD EEPROMs or equivalent live.
So, bus driver maintainers and users should feel free to remove the SPD
class from drivers those buses never have SPD EEPROMs or they don't
want the eeprom driver to bind to them. Likewise, feel free to add the
SPD class to any bus driver I might have missed.

Tighten error paths used by various i2c adapters (mostly x86) so
they return real fault/errno codes instead of a "-1" (which is
most often interpreted as "-EPERM"). Build tested, with eyeball
review.
One minor initial goal is to have adapters consistently return
the code "-ENXIO" when addressing a device doesn't get an ACK
response, at least in the probe paths where they are already
good at stifling related logspam.

The i2c-amd756 and i2c-viapro drivers make use of the driver_data
field of the PCI device ID. When adding device IDs dynamically (by
writing to the new_id sysfs file) you cannot set the value of this
field by default. It has to be allowed explicitly. Do that, and
check the value so that the user can't crash the kernel accidentally.

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).

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.

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!
