I would just like to start a discussion about consolidating (some of) the
ppc and ppc64 header files.

Marvellous!  In case it isn't completely obvious, you can often share
structure definitions between ppc32 and ppc64 by judicious selection of
types.  eg.

struct stays_the_same {
  long long some_64bit_var;
  int some_32bit_var;
}

If size matters, why not use an explicitly sized type like s64 to make it
explicit?

Sure, that's even better.
