[PATCH 08/23] x86, realmode: Allow absolute pa_* symbols in the realmode code

[Jarkko Sakkinen]

From: "H. Peter Anvin" <hpa@xxxxxxxxxxxxxxx>

Allow pa_* symbols to be absolute (outside any section) in the
realmode linker script.  Some versions of GNU ld are known to be
unhappy about symbols defined in a section that is otherwise empty.
