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