The enum definition assigns an 'id' to each register in power.

I guess it should be "each register in "struct pt_regs" of arch/powerpc

Right, that seems better.Will change the description like that.

Thanks a lot for reviewing the patch .

The order of these values in the enum definition are based on
the corresponding macros in arch/powerpc/include/uapi/asm/ptrace.h .
