Those two data areas can be completely separate, as they are on i386. Also i386 uses a separate kernel stack for interrupts.
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...
