* Revision 1.18 2005/01/12 08:10:14 starvik
- * Readded the change of frametype when handling kernel page fault fixup
+ * Re-added the change of frametype when handling kernel page fault fixup
* for v10. This is necessary to avoid that the CPU remakes the faulting
* access.

* Revision 1.8 2003/07/04 13:02:48 tobiasa
* Moved code snippet from arch/cris/mm/fault.c that searches for fixup code
- * to seperate function in arch-specific files.
+ * to separate function in arch-specific files.
