fix 256 node machines by increasing NODES_SHIFT value

We need 8 bits for the NODE_SHIFT otherwise 256 node systems fail in weird ways.

Thanks,
Jesse

I think I'm going to push back on this one since Linus wants to limit patches to stuff that affects (relatively) large number of folks, and I don't think there are more than a handful of >256 node systems out there (in fact, I've heard only of one). Otherwise, I'm OK with the patch, so we should include it in 2.6.1. Please retransmit after 2.6.1 is out.

Ditto for Jack's patch.

OK?

Yep, no problem. Just posting it for comments more than anything else.
