- *
- * 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
- * destroyed the flag register. Use instructions that don't affect the
- * flag register instead.

- * - (_system_call): Don't use r10 and don't save and restore it.
- * - (THREAD_ESP0): New constant.
- * - (_system_call): Inline set_esp0.
- *
- * Revision 1.12 2001/01/31 17:56:25 orjanf
- * Added definition of LTASK_PID and made it global.
- *
- * Revision 1.11 2001/01/10 21:13:29 bjornw

- * * New frame type used when an SBFS frame needs to be popped without

- * 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

- *
- * Revision 1.4 2000/08/02 13:59:30 bjornw
- * Removed olduname and uname from the syscall list
- *
- * Revision 1.3 2000/07/31 13:32:58 bjornw
