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

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

431 help
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.

Akira Takeuchi37e4ec92010-10-27 17:28:54 +0100439 serial DMA interrupts are allowed to interrupt normal disabled
