Acually I must mean the thread_info and not current. i386 only uses a
seperate stack if you use 4K stacks. I think others use seperate
interrupt stacks, however :(. Also, on thinking on it, I think some
archs don't call the registers pt_regs either. Oh, well, it was a
thought...
Waiting for its brother... :)
