A new build error appeared with CONFIG_PROC_FS disabled:
arch/x86/kernel/apm_32.c:1643:12: error: 'proc_apm_show' defined but not used
[-Werror=unused-function]
This marks the function as __maybe_unused to let the compiler drop
it silently.
Fixes: 3f3942aca6da ("proc: introduce proc_create_single{,_data}")
