- Adds code for the FPU stuff.

I admit I'm too dumb to understand the parts of the patch that covers this, but I'm still curious: IIRC FPU state is saved when entering from userland to kernel, and restored when going back. Also, IIUC no FPU code is used (allowed?) inside the kernel, right?

In what context/scenario does the FPU state need handling, if the above assumptions are correct?

P.S.: On making the kernel preemptible: AWESOME!
