The use of EXPORT_SYMBOL in static libraries potentially causes a problem for the llvm linker [1]. So, I want to forcibly link lib-y objects to vmlinux when CONFIG_MODULES=y. As a groundwork, we must fix multiple definitions that have previously been hidden by lib-y. The prom_cleanup() in this file is already marked as __weak (because it is overridden by the one in arch/mips/sgi-ip22/ip22-mc.c). I think it should be OK to do the same for these two.
