    [S390] cleanup trap handling · aa33c8cb
    Martin Schwidefsky authored
    Move the program interruption code and the translation exception identifier
    to the pt_regs structure as 'int_code' and 'int_parm_long' and make the
    first level interrupt handler in entry[64].S store the two values. That
    makes it possible to drop 'prot_addr' and 'trap_no' from the thread_struct
    and to reduce the number of arguments to a lot of functions. Finally
    un-inline do_trap. Overall this saves 5812 bytes in the .text section of
    the 64 bit kernel.
