PS3 patches for 2.6.23, take 3

Hi Paul.

I feel these patches are now ready. There are no outstanding issues. We did a lot of format cleanups since the last set, so these have a lot of small differences.

There are three new patches. Patch 31 to set CONFIG_MEMORY_HOTPLUG for PS3 builds, Patch 32 a collection of sparse warning fixes, and Patch 33 to update ps3_defconfig.
