This needs an empty function prototype for the .config variant where both
# CONFIG_BLK_DEV_INITRD is not set
# CONFIG_KEXEC is not set
otherwise:
arch/x86/kernel/setup.c:295:19: warning: ‘get_mem_size’ defined but not used
[-Wunused-function]
At a second glance though, a better fix might be if that whole
if-deffery in setup.c could be cleaned up a bit.
Thanks.
