    [PATCH] ppc64: Add definitions for new PTRACE calls · a94d3085
    Anton Blanchard authored
    - Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is
      as follows:
    
    /*
     * Get or set a debug register. The first 16 are DABR registers and the
     * second 16 are IABR registers.
     */
    #define PTRACE_GET_DEBUGREG    25
    #define PTRACE_SET_DEBUGREG    26
    
      DABR == data breakpoint and IABR = instruction breakpoint in IBM
      speak. We could split out the IABR into 2 more ptrace calls but I
      figured there was no need and 16 DABR registers should be more
      than enough (POWER4/POWER5 have one).
    
    - Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt
      find any standards on either of these so I copied what ia64 is
      doing. Again this might be better placed in
      include/asm-generic/siginfo.h
