[Arnd Bergmann]

Hi Linus,

Please pull from

	master.kernel.org:/pub/scm/linux/kernel/git/arnd/cell-2.6.git for-2.6.23

This is a number of changes that fell through the cracks because
it wasn't clear how we were going to merge it in the absence of paulus.
Mostly bug fixes, except a few features that should we should have
submitted all along:

* oprofile on Cell SPU
* SPU affinity
* Kdump saves SPU state
* drivers for I/O buffer memory and MSI on the Axon south bridge
