If memory is tight and a dynamic allocation fails there's no reason to 
make a bad situation worse by leaking memory.

mf_getSrcHistory potentially leaks pages[0-3]. I believe the right thing 
to do is to free that memory again before returning -ENOMEM - which is 
what this patch does.

I realize that the function is under '#if 0' so this probably doesn't 
matter much, but I assume that the function is still there for a reason 
(but I could be wrong, I don't know the powerpc code).
Anyway, I suggest we remove the leak.

Stephen is the iSeries maintainer, and I think he #if 0'ed the code. But
I don't think it will ever be un-ifdef'ed, so should probably just be
removed.

Well, only unofficially iseries maintainer :-)

Yes, just remove the whole function ... it was never used and never will
be.
