The get_frame_info() in process.c in kernel 2.6.16 no longer depends on a frame pointer. It would fit your needs better. I think you can use it with slight modifications. BTW, Is there any point using -fno-omit-frame-pointer on MIPS now? CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER=y is better for MIPS, isn't it? --- Atsushi Nemoto
