[PATCH] Generic CPU save/restore PM support

[Russell King - ARM Linux]

The following patch series implements infrastructure to save/restore
CPU state on suspend/resume PM events, and updates SA11x0, PXA and
Samsung platforms to use this.

Only only ARM920, ARM926, SA11x0, XScale, XScale3, V6 and V7 CPUs are
supported.

I've build-tested this for Assabet, PXA, and S3C2410, and boot tested
on Assabet.

Please send your acks/tested bys etc.
