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