I think it needs quite a bit of rework - I certainly don't like all
those CP15 register accesses there - that's asking for lots of ifdefs
to spring up as more CPUs are supported.

Eg, what about ensuring that state such as iWMMXt on PXA CPUs is
properly restored?

We already have code which knows what needs to be saved across a
power-off transition - its what we use for our normal suspend/resume
functionality, so we should look at re-using that code for hibernate
as well.  We really don't want to be maintaining two sets of code
doing the same thing.
