 219           you have a system with more than one CPU, say Y.
 220
 221           If you say N here, the kernel will run on single and multiprocessor
 222           machines, but will use only one CPU of a multiprocessor machine. If
 223           you say Y here, the kernel will run on many, but not all,
 224           singleprocessor machines. On a singleprocessor machine, the kernel
 225           will run faster if you say N here.

 250           This option removes the E2/R2 register from the set available to gcc
 251           for normal use and instead uses it to store the address of the
 252           current process's task_struct whilst in the kernel.
 253
 254           This means the kernel doesn't need to calculate the address each time
 255           "current" is used (take SP, AND with mask and dereference pointer
 256           just to get the address), and instead can just use E2+offset

 467           local_irq_disable() doesn't actually disable maskable interrupts -
 468           what it does is restrict the levels of interrupt which are permitted
 469           (a lower level indicates a higher priority) by lowering the value in
 470           EPSW.IM from 7.  Any interrupt is permitted for which the level is
 471           lower than EPSW.IM.
 472
 473           Certain interrupts, such as GDBSTUB and virtual MN10300 on-chip
 474           serial DMA interrupts are allowed to interrupt normal disabled
 475           sections.
