[PATCH] m68knommu: cleanup setup.c
A cleanup of m68knommu/kernel/setup.c : - No need to initialize global pointers to NULL, they will have that value automatically, and they eat up space in my data segment image in FLASH. - Remove get_cpuinfo. It has been replaced by show_cpuinfo. Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
