When compiling uml on x86_64:
MODPOST vmlinux.o
WARNING: vmlinux.o (.__syscall_stub.2): unexpected non-allocatable section.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.
Because modpost checks for missing SHF_ALLOC section flag. So just add
it.
