+When I compiled uml on x86_64, I got this warning:
+
+  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. :)
