136 Enable this to be lazy in the saving of the FPU state to the owning
137 task's thread struct. This is useful if most tasks on the system
138 don't use the FPU as only those tasks that use it will pass it
139 between them, and the state needn't be saved for a task that isn't
140 using it.
141
142 This can't be so easily used on SMP as the process that owns the FPU
143 state on a CPU may be currently running on another CPU, so for the
144 moment, it is disabled.

217 This option removes the E2/R2 register from the set available to gcc
218 for normal use and instead uses it to store the address of the
219 current process's task_struct whilst in the kernel.
220
221 This means the kernel doesn't need to calculate the address each time
222 "current" is used (take SP, AND with mask and dereference pointer
223 just to get the address), and instead can just use E2+offset
224 addressing each time.

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.
