	/* binutils < 2.18 has a bug that makes it misbehave when taking an
	   ELF file with all segments at load address 0 as input.  This
	   happens when running "strip" on vmlinux, because of the AT() magic
	   in this linker script.  People using GCC >= 4.2 won't run into
	   this problem, because the "build-id" support will put some data
	   into the "notes" segment (at a non-zero load address).

	   To work around this, we force some data into both the "dummy"
	   segment and the kernel segment, so the dummy segment will get a
	   non-zero load address.  It's not enough to always create the
	   "notes" segment, since if nothing gets assigned to it, its load
	   address will be zero.  */
