this patch made it into next-20140623 as 5e49555277df (mm: memcontrol: rewrite charge API) and it makes efm32_defconfig (ARCH=arm) fail with:
CC mm/swap.o mm/swap.c: In function 'lru_cache_add_active_or_unevictable': mm/swap.c:719:2: error: implicit declaration of function 'TestSetPageMlocked' [-Werror=implicit-function-declaration] if (!TestSetPageMlocked(page)) { ^ cc1: some warnings being treated as errors scripts/Makefile.build:257: recipe for target 'mm/swap.o' failed make[3]: *** [mm/swap.o] Error 1 Makefile:1471: recipe for target 'mm/swap.o' failed
imx_v4_v5_defconfig works, so probably the thing that makes efm32_defconfig fail is CONFIG_MMU=n.
Best regards Uwe
