Anyway, I know the LLD linker's behavior in case that was the intention... ) I think it'd be good to know the reason why these dynamic relocations are produced and fix the root cause. arch/x86/kernel/vmlinux.lds.S asserts no dynamic relocation: ASSERT(SIZEOF(.rela.dyn) == 0, "Unexpected run-time relocations (.rela) detected!")
