mm/kmemleak.c: fix unused-function warning
commit dce5b0bdeec61bdbee56121ceb1d014151d5cab1 upstream. The only references outside of the #ifdef have been removed, so now we get a warning in non-SMP configurations: mm/kmemleak.c:1404:13: error: unused function 'scan_large_block' [-Werror,-Wunused-function] Add a new #ifdef around it. Link: http://lkml.kernel.org/r/20190416123148.3502045-1-arnd@arndb.de Fixes: 298a32b13208 ("kmemleak: powerpc: skip scanning holes in the .bss section") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Catalin Marinas <catalin.marinas@arm.com> Cc: Vincent Whitchurch <vincent.whitchurch@axis.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: Nobuhiro Iwamatsu <nobuhiro1.iwamatsu@toshiba.co.jp> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
