Pull powerpc update from Benjamin Herrenschmidt:
 "The main highlight is probably some base POWER8 support.  There's more
  to come such as transactional memory support but that will wait for
  the next one.

  Overall it's pretty quiet, or rather I've been pretty poor at picking
  things up from patchwork and reviewing them this time around and Kumar
  no better on the FSL side it seems..."

PPC: net: bpf_jit_comp: add XOR instruction for BPF JIT

2012-11-18T03:12:47+00:00

This patch is a follow-up for patch "filter: add XOR instruction for use
with X/K" that implements BPF PowerPC JIT parts for the BPF XOR operation.

powerpc/47x: Use the new ppc-opcode infrastructure

2012-11-15T01:59:24+00:00

Don't use 47x only #defines for TLBIVAX or ICBT, supply and use helpers
in ppc-opcode.h

This fixes a compile breakage.

powerpc: Add denormalisation exception handling for POWER6/7

2012-09-17T06:31:47+00:00

On POWER6 and POWER7 if the input operand to an instruction is a
denormalised single precision binary floating point value we can take
a denormalisation exception where it's expected that the hypervisor
(HV=1) will fix up the inputs before the instruction is run.

This adds code to handle this denormalisation exception for POWER6 and
POWER7.

It also add a CONFIG_PPC_DENORMALISATION option and sets it in
pseries/ppc64_defconfig.

This is useful on bare metal systems only.  Based on patch from Milton
Miller.

powerpc: Enforce usage of RA 0-R31 where possible

2012-07-10T09:18:35+00:00

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.

powerpc: Add defines for RA 0-R31

powerpc: Enforce usage of R0-R31 where possible

2012-07-10T09:18:30+00:00

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.

powerpc: Start using ___PPC_RA/B/S/T where necessary

2012-07-10T09:18:25+00:00

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.
