Hi,

In today's linus's git tree, uml doesn't compile when it's configured for 
only TT-mode.

This regression caused by:

Thanks for the report and the patch, however I want to fix things a bit 
differently... the thing _should_ compile anyway.

The macro is declared anyway and the var should exist anyway.
The problem is just that they aren't declared, I think. Will fix.

Junichi, ignore what I said earlier.  If Blaisorblade wants to fix it 
differently, then we'll use his patch instead.
