"PERF_REG_POWERPC_RESULT" will always be zero, because of regs_get_register (asm/ptrace.h), that you call in patch 3 of this patchset, will check for MAX_REG_OFFSET and return 0 for "result".

The enum definition assigns an 'id' to each register in "struct pt_regs" of arch/powerpc.The order of these values in the enum definition are based on the corresponding macros in arch/powerpc/include/uapi/asm/ptrace.h .
