There is no reason i2o_max_drivers must be a power of two. This patch
eliminates such a constraint.

Maximum number of I2O drivers which could be registered is configurable by
max_drivers module parameter.
But the module parameter is ignored and default value (I2O_MAX_DRIVERS = 8)
is used in the loops to notify all registered drivers.

i2o_driver_register() initalizes event queue for driver only when
drv->event is set. So similarly the event queue should be destroyed only
when drv->event is set in the error path. Otherwise destroy_workqueue()
will called with NULL.

i2o_exec_exit and i2o_driver_exit were marked as __exit which is a bug
because both are invoked from __init and __exit functions.

- Removed some kmalloc's with __GFP_ZERO and replace it with memset()
because it didn't work properly.
- Fixed returned message frame in i2o_cfg_passthru() which caused raidutils
to display wrong error message in case a disk was missing.
- Fixed size of printk() in i2o_scsi.c.
- Fixed get_device() and put_device() in probing of the I2O controller.

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
to also have i2c_device class that mirros i2o bus.

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!
