ppc doesn't have a standard FP location ?

Not really no, it's the sp (r1). r31 might be considered a "frame
pointer" under some circumstances but there isn't much you can do with
it, it's really r1 that gives you the ability to backtrace (each stack
frame contains a pointer to the next one).

+#define profile_pc(regs) GET_IP(regs)

pretty sure you don't need this as asm-generic/ptrace.h already has a 
definition for you
