Subject: [PATCH 14/18] powerpc: start using ___PPC_RA/B/S/T where necessary
Date: Tue, 26 Jun 2012 09:33:21 +1000 [thread overview]
Message-ID: <20120625233321.B9FE5D43683@localhost.localdomain> (raw)
In-Reply-To: <1340667187.357853.615199632713.qpush@ale>
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.
