Maciej W. Rozycki 3b143cca6e MIPS: traps: Correct the SIGTRAP debug ABI in `do_watch' and `do_trap_or_bp' ... Follow our own rules set in <asm/siginfo.h> for SIGTRAP signals issued from `do_watch' and `do_trap_or_bp' by setting the signal code to TRAP_HWBKPT and TRAP_BRKPT respectively, for Watch exceptions and for those Breakpoint exceptions whose originating BREAK instruction's code does not have a special meaning. Keep Trap exceptions unaffected as these are not debug events. No existing user software is expected to examine signal codes for these signals as SI_KERNEL has been always used here. This change makes the MIPS port more like other Linux ports, which reduces the complexity and provides for performance improvement in GDB. Signed-off-by: Maciej W.
