remove all references to .dynsym
Discard all .dynsym sections from linker scripts Remove all __dynsym_start definitions from linker scripts Remove all __dynsym_start references from the codebase Note: this touches include/asm-generic/sections.h, which is not ARM-specific, but actual uses of __dynsym_start are only in ARM, so this patch can safely go through the ARM repository.
