The newly introduced mm_pgtables_bytes() function has two definitions with slightly different prototypes. The one used for CONFIG_MMU=n causes a compile-time warning: In file included from include/linux/kernel.h:13:0, from mm/debug.c:8: mm/debug.c: In function 'dump_mm': mm/debug.c:137:21: error: passing argument 1 of 'mm_pgtables_bytes' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers] This changes it to be the same as the other one and avoid the warning.
