Subject[PATCH] kmemleak: fix unused-function warning
Date
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.

Fixes: 298a32b13208 ("kmemleak: powerpc: skip scanning holes in the .bss section")
