When I patch a generic 2.6.16.6 kernel with adeos-ipipe-2.6.14-ppc-1.3-03 and ipipe-tracer-2.6.14-ppc-1.3-03 and then enable the ipipe tracer I receive the undefined _mcount errors from the kernel build. This happens even without the motorola patch.
During the kernel build arch/ppc/kernel/ipipe-mcount.S is compiled to arch/ppc/kernel/ipipe-mcount.o, but for some reason ld still complains that _mcount is undefined.
