Some versions of the 32-bit ARM linker seem to treat the absence of a .note.GNU-stack section as implying an executable stack, and will print a warning that this is deprecated behaviour. Silence the warning by adding a .note.GNU-stack section to each assembly file and retaining the sections in the Linux linker script. Signed-off-by: Michael Brown <mcb30@ipxe.org>
