[PATCH] ppc64: Add definitions for new PTRACE calls
- 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
