This patch contains the following possible cleanups: - make the following needlessly global code static: - config.c: sun3_bootmem_alloc() - config.c: sun3_sched_init() - dvma.c: dvma_page() - idprom.c: struct Sun_Machines[] - mmu_emu.c: struct ctx_alloc[] - sun3dvma.c: iommu_use[] - sun3ints.c: led_pattern[] - remove the unused sbus.c Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
