+ 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. */
