Move the HAVE_ARCH_BUG/HAVE_ARCH_WARN_ON definitions underneath
CONFIG_GENERIC_BUG. This is needed for BUGFLAG_WARNING usage.

The CPU family abstraction already exists, so move out the PXSEG
definition for each one. SH-2A already has this special cased,
and SH-5 will as well.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (54 commits)
MAINTIANERS: just use Mike gmail e-mail for contact and pawn the serial driver off onto Sonic
[Blackfin] arch: remove old I2C BF54x porting.
[Blackfin] arch: Add the semtimedop syscall. Upstream uClibc doesn't compile without it.
[Blackfin] arch: fix bug kernel boot message: memory information is not reasonable
[Blackfin] arch: use common flash driver to setup partitions rather than the bf5xx-flash driver
[Blackfin] arch: Fix bug - kernel build with Debug option enabled fails to boot up
[Blackfin] arch: Fix bug Only RTC interrupt can wake up deeper sleep core.
[Blackfin] arch: Add proper SW System Reset delay sequence
[Blackfin] arch: Update copyright date
[Blackfin] arch: GPIO API cleanup and anomaly update
[Blackfin] arch: Fix BUG gpio_direction_output API is not compatitable with GENERIC_GPIO API interface
[Blackfin] arch: Initial checkin of the memory protection support.
[Blackfin] arch: set_bfin_dma_config shouldnt set SYNC or RESTART by default - add argument or option
[Blackfin] arch: Add some comments - fix semicolons
[Blackfin] arch: move all code related to CPLB handling into a new subdirectory under kernel/
[Blackfin] arch: print out list of modules if kernel is crashing and tell people if the kernel is tainted
[Blackfin] arch: enable generic GPIO based I2C driver in STAMP-BF533, EZKIT-BF533 and EZKIT-BF561 boards
[Blackfin] arch: Don't oops_in_progress if single step is comming from the kernel
[Blackfin] arch: Fix BUG - kernel sometimes would stuck with KEYBOARD_GPIO on
[Blackfin] arch: update to latest anomaly sheets
...
This adds a i2c_new_dummy() primitive to help work with devices
that consume multiple addresses, which include many I2C eeproms
and at least one RTC.

The i2c_adapter.clients list of i2c_client nodes duplicates driver
model state. This patch starts removing that list, letting us remove
most existing users of those i2c-core lists.
* The core I2C code now iterates over the driver model's list instead
of the i2c-internal one in some places where it's safe:
- Passing a command/ioctl to each client, a mechanims
used almost exclusively by DVB adapters;
- Device address checking, in both i2c-core and i2c-dev.
* Provide i2c_verify_client() to use with driver model iterators.
* Flag the relevant i2c_adapter and i2c_client fields as deprecated,
to help prevent new users from appearing.
For the moment the list needs to stick around, since some issues show
up when deleting devices created by legacy I2C drivers. (They don't
follow standard driver model rules. Removing those devices can cause
self-deadlocks.)

Add polling I2C transfer implementation for PXA I2C. This is needed
for cases where I2C transactions have to occur at times interrups are
disabled.

Discard all I2C driver IDs that aren't used anywhere. That's not just a
couple of them, but more like 49 or one quarter of all defined IDs! And
this is just a first pass, next will come all IDs that are set but
never used, or used but never set.

Move the tps65010 header file from the OMAP arch directory to the
more generic <linux/i2c/...> directory, and remove the spurious
dependency of this driver on OMAP.

i2c_driver.list is superfluous, this list duplicates the one
maintained by the driver core. Drop it.

Use more standard prototypes for i2c_use_client() and
i2c_release_client(). The former now returns a pointer to the client,
and the latter no longer returns anything. This matches what all other
subsystems do.
