parisc, kdb-parisc patches for -pa23 can be found at: http://www.baldric.uwo.ca/~carlos/kdb-parisc/ No feature enhancements or bug fixes, just a 'it works with -pa23' changes. There were only a few changes to be made to /arch/parisc/kernel/traps.c. I put together the changes based on the -pa11 kdb patches. c.
