m68k: Merge mmu and non-mmu versions of sys_call_table
Impact for nommu: - Store table in .rodata instead of .text, - Let kernel/sys_ni.c handle the stubbing of MMU-only syscalls, - Implement sys_mremap and sys_nfsservct, - Remove unused padding at the end of the table. Impact for mmu: - Store table in .rodata instead of .data. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Greg Ungerer <gerg@uclinux.org>
