The I2O driver uses two semaphores as mutexes.  Use the mutex API instead of
the (binary) semaphores.

i2o_scsi: handle sysfs failure

i2o_device:
 * convert i2o_device_add() to return integer error code
   rather than pointer.  Fortunately -nobody- checks the return code of
   this function, so changing has nil impact.
 * handle errors thrown by device_register()

More work in i2o_device remains.

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.

In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch.  This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other.  So if any
hunk rejects or gets in the way of other patches, just drop it.  My scripts
will pick it up again in the next round.

I2O: cleanup - remove i2o_device_class

I2O devices reside on their own bus so there should be no reason

I2O: remove i2o_device_class_interface misuse

The intent of class interfaces was to provide different
'views' at the same object, not just run some code every
time a new class device is registered. Kill interface
structure, make class core register default attributes
and set up sysfs links right when registering class
devices.

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!
