First 5 patches convert us to %r0-31.
Next 12 convert make using R0-31 required in macros.
Last 2 convert instructions where ra = r0 we use 0 rather than the
register value (as suggested by Andreas).
Version 2 adds:
ra = 0 idea (as Andreas suggested)
Fixes for 32bit KVM (added
We are going to use these later and convert r0 to %r0 etc.

mtocrf define is just a wrapper around the real instructions so we can
just use real register names here (ie. lower case).
Also remove braces in macro so this is possible.

Now have ___PPC_RA/B/S/T we can use it in some places. These are
places where we can't use the existing defines which will soon enforce
R0-R31 usage.
The macros being changed here are being used in inline asm, which
can't convert to enforce the R0-R31 usage.

Some macros use RA where when RA=R0 the values is 0, so make this

There are a few things that make the existing hw tablewalk handlers
unsuitable for e6500:
- Indirect entries go in TLB1 (though the resulting direct entries go in

- It has threads, but no tlbsrx. -- so we need a spinlock and

That per-se doesn't justify a whole new handler... patching
