Subject: Re: [PATCH] Missing symbol prefix on vmlinux.lds.h

Sorry.

I got error ARCH=h8300.
init/main.c:781: undefined reference to `___early_initcall_end'

Same problem have
__start___bug_table
__stop___bug_table
__tracedata_start
__tracedata_end
__per_cpu_start
__per_cpu_end

If define symbol in vmlinux.lds, Use VMLINUX_SYMBOL macro.
VMLINUX_SYMBOL is add prefix charactor.
