156 Enable this to be lazy in the saving of the FPU state to the owning
157 task's thread struct. This is useful if most tasks on the system
158 don't use the FPU as only those tasks that use it will pass it
159 between them, and the state needn't be saved for a task that isn't
160 using it.
161
162 This can't be so easily used on SMP as the process that owns the FPU
163 state on a CPU may be currently running on another CPU, so for the
164 moment, it is disabled.

241 This option removes the E2/R2 register from the set available to gcc
242 for normal use and instead uses it to store the address of the
243 current process's task_struct whilst in the kernel.
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
247 just to get the address), and instead can just use E2+offset
248 addressing each time.

457 help
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.
