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. */ | |
