18 /* binutils < 2.18 has a bug that makes it misbehave when taking an
19 ELF file with all segments at load address 0 as input. This
20 happens when running "strip" on vmlinux, because of the AT() magic
21 in this linker script. People using GCC >= 4.2 won't run into
22 this problem, because the "build-id" support will put some data
23 into the "notes" segment (at a non-zero load address).
24
25 To work around this, we force some data into both the "dummy"
26 segment and the kernel segment, so the dummy segment will get a
27 non-zero load address. It's not enough to always create the
28 "notes" segment, since if nothing gets assigned to it, its load
29 address will be zero. */
