Missing symbol prefix on vmlinux.lds.h
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
When defining a symbol in vmlinux.lds, use the VMLINUX_SYMBOL macro.
VMLINUX_SYMBOL adds a prefix charactor.
You can't just use straight symbol names in common header files as they
dont take into consideration weird arch-specific ABI conventions. in the
case of Blackfin/h8300, the ABI dictates that any C-visible symbols have
an underscore prefixed to them. Thus all symbols in vmlinux.lds.h need to
be wrapped in VMLINUX_SYMBOL() so that each arch can put hide this magic
in their own files.
