Well, this morning I merged the ptrace ->regset_get() updates from Al,
and that brought in a different conflict.

I _think_ I resolved it correctly, but while the new model is fairly
readable, the old one sure wasn't, and who knows how messed up my
attempt to sort it out was. I don't know the pkey details on powerpc..

So I'd appreciate it if both Al and Aneesh Kumar would check that what
I did to pkey_get() in arch/powerpc/kernel/ptrace/ptrace-view.c makes
sense and works..

Side note - it might have been cleaner to just make it do

        membuf_store(&to, target->thread.amr);
        membuf_store(&to, target->thread.iamr);
        return membuf_store(&to, default_uamor);

instead of doing that membuf_write() for the first two ones and then
the membuf_store() for the uamor field, but I did what I did to keep
the logic as close to what it used to be as possible.

If I messed up, I apologize.

And if you agree that making it three membuf_store() instead of that
odd "depend on the exact order of the thread struct and pick two
consecutive values", I'll leave that to you as a separate cleanup.
