[PATCH] ppc64: remove hidden -fno-omit-frame-pointer for schedule.c
While looking at code generated by gcc4.0 I noticed some functions still had frame pointers, even after we stopped ppc64 from defining CONFIG_FRAME_POINTER. It turns out kernel/Makefile hardwires -fno-omit-frame-pointer on when compiling schedule.c. Create CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER and define it on architectures that dont require frame pointers in sched.c code. (akpm: blame me for the name) Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
