Subject: x86, realmode: Allow absolute pa_* symbols in the realmode code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2a6de3148cfd1a0240a85ea4a1cad34d250d882f;p=linux-beck.git

x86, realmode: Allow absolute pa_* symbols in the realmode code

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.
