arch/arm/mm/ioremap.c:67: warning: control reaches end of non-void function
mm/bootmem.c: In function ‘mark_bootmem’:
mm/bootmem.c:321: warning: control reaches end of non-void function
fs/dcache.c: In function ‘d_materialise_unique’:
fs/dcache.c:1875: warning: control reaches end of non-void function
fs/nfs/client.c: In function ‘nfs_sockaddr_match_ipaddr’:
