Linking with ld.lld via $ make LD=ld.lld produces the warning: ld.lld: warning: cannot find entry symbol _start; defaulting to 0x1000 Linking with ld.bfd shows the default entry is 0x1000: $ readelf -h arch/x86/realmode/rm/realmode.elf | grep Entry Entry point address: 0x1000 While ld.lld is being pedantic, just set the entry point explicitly, instead of depending on the implicit default. The symbol pa_text_start refers to the start of the .text section, which may not be at 0x1000 if the preceding sections listed in arch/x86/realmode/rm/realmode.lds.S were large enough. This matches behavior in arch/x86/boot/setup.ld.
