- *  Updated after review, should now handle USB interrupts correctly.
- *
- *  Revision 1.17  2001/03/21 16:12:55  bjornw
- *  * Always make room for the cpu status record in the frame, in order to
- *    use the same framelength and layout for both mmu busfaults and normal
- *    irqs. No need to check for the explicit CRIS_FRAME_FIXUP type anymore.
- *  * Fixed bug with using addq for popping the stack in the epilogue - it

- *    flag register instead.

- *
- *  Revision 1.13  2001/02/15 08:40:55  perf
- *  H-P by way of perf;
- *  - (_system_call): Don't read system call function address into r1.
- *  - (RBFExit): There is no such thing as a null pop.  Adjust sp by addq.
- *  - (_system_call): Don't use r10 and don't save and restore it.
- *  - (THREAD_ESP0): New constant.
- *  - (_system_call): Inline set_esp0.

- *    idea)
- *
- *  Revision 1.8  2000/11/17 16:53:35  bjornw
- *  Added detection of frame-type in Rexit, so that mmu_bus_fault can
- *  use ret_from_intr in the return-path to check for signals (like SEGV)
- *  and other foul things that might have occurred during the fault.
- *
- *  Revision 1.7  2000/10/06 15:04:28  bjornw
- *  Include mof in register savings
- *
