Trivial patches for sparc64 in 2.5.7

Trivial patches for sparc64 in 2.5.7

[Holzrichter, Bruce]

I can't imagine that you don't have these already, but here's some fixes to
/arch/sparc64 stuff to replace the p_pptr with parent on sparc64 that got
changed in 2.5.7

On a side note, I don't get to do to much with the kernel, so I hope my
little fixes and e-mails to you don't bug you too much.  I like the sparc,
because it doesn't get as much traffic, and there's more room for finding
things like this as I teach myself more about the kernel internals.

Thanks for the submission, but yes these are in my bitkeeper tree
already :-)
