#     powerpc/ftrace: Activate HAVE_DYNAMIC_FTRACE_WITH_REGS on PPC32
#     
#     Unlike PPC64, PPC32 doesn't require any special compiler option
#     to get _mcount() call not clobbering registers.
#     
#     Provide ftrace_regs_caller() and ftrace_regs_call() and activate
#     HAVE_DYNAMIC_FTRACE_WITH_REGS.
#     
#     That's heavily copied from ftrace_64_mprofile.S
#     
#     For the time being leave livepatching aside, it will come with
#     following patch.
