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

216 for normal use and instead uses it to store the address of the
217 current process's task_struct whilst in the kernel.

219 This means the kernel doesn't need to calculate the address each time
220 "current" is used (take SP, AND with mask and dereference pointer
221 just to get the address), and instead can just use E2+offset
222 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.
439
David Howells67ddb402011-03-18 16:54:30 +0000440 Certain interrupts, such as DEBUGGER and virtual MN10300 on-chip
Akira Takeuchi37e4ec92010-10-27 17:28:54 +0100441 serial DMA interrupts are allowed to interrupt normal disabled
