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 4 add:
Fixes for bpf_jit code
Version 3 adds:
Fixes for chroma (moved some defines ppc_asm.h -> ppc-opcode.h)
Fixed comment in sldi patch to reflect new change (thanks Segher)
Version 2 adds:
ra = 0 idea (as Andreas suggested)
Fixes for 32bit KVM (added ppc44x_defconfig to my testing)
Based on mpe's next tree which has Antons power7 copy patches which
needed fixes for this

We are going to use these later and convert r0 to %r0 etc.

The assembler doesn't take %r0 register arguments in braces, so remove them.

Anything that uses a constructed instruction (ie. from ppc-opcode.h),
need to use the new R0 macro, as %r0 is not going to work.
Also convert usages of macros where we are just determining an offset
(usually for a load/store), like:
std r14,STK_REG(r14)(r1)
Can't use STK_REG(r14) as %r14 doesn't work in the STK_REG macro since
it's just calculating an offset.

Since we are taking a registers, this should never have been an sldi.
Talking to paulus offline, this is the correct fix.
Was introduced by:
commit 19ccb76a1938ab364a412253daec64613acbf3df
Author: Paul Mackerras <paulus@samba.org>
Date: Sat Jul 23 17:42:46 2011 +1000
Talking to paulus, this shouldn't be a literal.

LOAD_REG_ADDR define is just a wrapper around real instructions so we
can just use real register names here (ie. lower case).

These macros are using integers where they could be using logical
names since they take registers.
We are going to enforce this soon, so fix these up now.

We need to do this so we can enforce the name of a and b in called
macros PPC_RA/B later.

These are currently the same as __PPC_RA/B/S/T but we'll wrap them
soon.

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.
bpf_jit uses a mix of both generated and non-generated with the same
code, so just convert all these to use the ___PPC_R versions which
won't enforce R usage later.

Enforce the use of R0-R31 in macros where possible now we have all the
fixes in.
R0-R31 macros are removed here so that can't be used anymore. They
should not be defined anywhere.

Some macros use RA where when RA=R0 the values is 0, so make this
the enforced mnemonic in the macro.
Idea suggested by Andreas Schwab.
