patches for current -mm kernels

[Andrew Morton]

I had to hack some fixes together to get a working ppc64 kernel with
current Linus plus current me.

I'll do 2.6.0-test2-mm3 today.  It works on ppc64.



Implement local.h for ppc64.  It's only 32-bit at present.  ppc64 doesn't
seem to support atomic64_t.
