70694a8bab powerpc/cell: Cleanup sysreset_hack for IBM cell blades

IBM Cell blades. The code is moves from pervasive.c into ras.c and
gets it's own init method.

acf7d76827 [POWERPC] cell: add RAS support
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.

c902be71dc [PATCH] cell: enable pause(0) in cpu_idle
This patch enables support for pause(0) power management state
for the Cell Broadband Processor, which is import for power efficient
operation. The pervasive infrastructure will in the future enable
us to introduce more functionality specific to the Cell's
pervasive unit.
