A bunch of ifdefs is not a good start for a file you're claiming is now
generic for all powerpc.
Certainly you shouldn't be calling pseries stuff based only on the
absence of powernv.
And do you not support building one kernel that supports both pseries
and powernv?

Here's another example. get_lppaca() will only build on book3s -- and
yet we get requests for e500 code to use this file.
