This is a first version of support for the Cell BE "Reliability, Availability and Serviceability" features. It doesn't yet handle some of the RAS interrupts (the ones described in iic_is/iic_irr), I'm still working on a proper way to expose these. They are essentially a cascaded controller by themselves (sic !) though I may just handle them locally to the iic driver. I need also to sync with David Erb on the way he hooked in the performance monitor interrupt. So that's all for 2.6.17 and I'll do more work on that with my rework of the powerpc interrupt layer that I'm hacking on at the moment.
