Ok that would be important. I also think that the approach may be used
in kernel to reduce the overhead of CONFIG_PREEMPT and also to implement
fast versions of this_cpu_ops for non x86 architectures and maybe even
optimize the x86 variants if interrupts also can detect critical sections
and restart at defined points.
