 214           you say Y here, the kernel will run on many, but not all,

 244
 245           This means the kernel doesn't need to calculate the address each time
 246           "current" is used (take SP, AND with mask and dereference pointer

 458           local_irq_disable() doesn't actually disable maskable interrupts -
 459           what it does is restrict the levels of interrupt which are permitted
 460           (a lower level indicates a higher priority) by lowering the value in
 461           EPSW.IM from 7.  Any interrupt is permitted for which the level is
 462           lower than EPSW.IM.
 463
 464           Certain interrupts, such as GDBSTUB and virtual MN10300 on-chip
 465           serial DMA interrupts are allowed to interrupt normal disabled
 466           sections.
