218 
219           This means the kernel doesn't need to calculate the address each time
220           "current" is used (take SP, AND with mask and dereference pointer

434           local_irq_disable() doesn't actually disable maskable interrupts -
435           what it does is restrict the levels of interrupt which are permitted
436           (a lower level indicates a higher priority) by lowering the value in
437           EPSW.IM from 7.  Any interrupt is permitted for which the level is
438           lower than EPSW.IM.
439 
440           Certain interrupts, such as DEBUGGER and virtual MN10300 on-chip
441           serial DMA interrupts are allowed to interrupt normal disabled
442           sections.
