commit 7be0d19c751b02db778ca95e3274d5ea7f31891c upstream.
Selecting CONFIG_SAMSUNG_PM_DEBUG (depending on CONFIG_DEBUG_LL) but without CONFIG_MMU leads to build errors:
arch/arm/plat-samsung/pm-debug.c: In function ‘s3c_pm_uart_base’: arch/arm/plat-samsung/pm-debug.c:57:2: error: implicit declaration of function ‘debug_ll_addr’ [-Werror=implicit-function-declaration]
