Hi, Some boards have, eg.: arch/mips/momentum/ocelot_3/prom.c:242:void __init prom_free_prom_memory(void) yet free_initmem() expects a return: arch/mips/mm/init.c:285:extern unsigned long prom_free_prom_memory(void); arch/mips/mm/init.c:291: freed = prom_free_prom_memory(); Fix those up and return 0 instead, just like everyone else does.
