+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. :)

+commit 67dac695a1f33716f3e35c2292e7391410d58751
+Author: Paul Bolle <pebolle@tiscali.nl>

+
+ um: add work around for build problems with bash 4
+
+ Building User Mode Linux fails with bash 4. The UML Makefiles use an
+ environment variable called CPPFLAGS_vmlinux.lds but bash 4 does not
+ export environment variables with a dot in their name. Add a hack to
+ allow building UML with bash 4 (which should not affect other shells).
