arch/x86/kernel/ksysfs.c: In function 'get_setup_data_paddr':
>> arch/x86/kernel/ksysfs.c:81:3: error: implicit declaration of function 'ioremap_cache' [-Werror=implicit-function-declaration]
data = ioremap_cache(pa_data, sizeof(*data));
^
>> arch/x86/kernel/ksysfs.c:86:3: error: implicit declaration of function 'iounmap' [-Werror=implicit-function-declaration]
iounmap(data);

Fix it by including <asm/io.h> in ksysfs.c
