Module Name:    src

Modified Files:
        src/sys/arch/hppa/hppa: db_interface.c trap.S

Log Message:
Improve ddb backtraces by:

        - Starting with the right set of fp, pc, and rp in all cases.
        - Dropping the argument printing stuff as it could never work.
        - Backtrace through traps and decode syscalls properly by
          making sure the trapframe is at a known offset from the stack
          pointer in both cases. Also, ensure that the frame pointer
          is zero so that we can detect traps.
