Re: [PATCH] powerpc: Define and use PPC_ELF_ABI_v2

We're approaching 20 locations where we need to check for ELF ABI v2.
That's fine, except the logic is a bit awkward, because we have to check
that _CALL_ELF is defined and then what its value is.

So check it once in asm/types.h and define PPC_ELF_ABI_v2 when ELF ABI
v2 is detected.

We don't add explicit includes of asm/types.h because it's included
basically everywhere via compiler.h.

Thanks for doing this!

Does it make sense to call this PPC64_ELF_ABI_V2 since this is 64-bit 
only, and include check for CONFIG_PPC64 as well?

Apart from that:
