These build warnings with W=1 are related to arm header includes. arm64
expand syscall macro such that '__arm64_' is added to the syscall
handler name. Hence the include  linux/syscall.h that have below
prototype is not sufficient.   
asmlinkage long sys_set_mempolicy_home_node(unsigned long start, unsigned long len,
					    unsigned long home_node,
					    unsigned long flags);


That should be fixed outside this series.
