[PATCH] powerpc: Extends HCALL interface for InfiniBand usage

This extends the HCALL interface for InfiniBand usage. I've
made the patch against the linux-2.6 git tree and Segher's patch:
[PATCH] Change H_StudlyCaps to H_SHOUTING_CAPS

We moved this into the common powerpc code based on comments we
got after posting the first eHCA InfiniBand device driver patch.
