sh: off by one BUG_ON() in setup_bootmem_node()
This off by one bug is harmless but it upsets the static checkers and the code is obvious so it doesn't hurt to fix it. The Smatch warning is: arch/sh/mm/numa.c:47 setup_bootmem_node() error: buffer overflow 'node_data' 1024 <= 1024 Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Cc: Paul Mundt <lethal@linux-sh.org> Acked-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
