Thomas, Ingo, and Peter(s),

On IRC, Peter Zijlstra mentioned to me the difference between
32bit and 64bit x86 on how thread_info is handled with interrupts.
I mentioned that they should be more the same, and Peter agreed.

I decided to do so, and ended up with the following patches.
I marked this for v3.2 as it should be tested a bit before going into
mainline. I've ran several configs on it, but more testing should be done.

Some of the patches are clean ups, but the main ones are patch 3 and 4
that do the work to convert 32bit of thread_info to be more like
the 64bit.
