- 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!
