When building with W=1: arch/m68k/mm/motorola.c:414:13: warning: no previous prototype for ‘paging_init’ [-Wmissing-prototypes] 414 | void __init paging_init(void) | ^~~~~~~~~~~ arch/m68k/mm/sun3mmu.c:36:13: warning: no previous prototype for ‘paging_init’ [-Wmissing-prototypes] 36 | void __init paging_init(void) | ^~~~~~~~~~~ Fix this by consolidating the multiple prototypes into the common <asm/pgtable.h>.
