| 	   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.  */ | ||||
