Two correct patches for the 4.1 release clashed in a way that
caused modpost to fail badly, with hundreds warnings like
WARNING: vmlinux.o(__ex_table+0x1014): Section mismatch in reference from the (unknown reference) (unknown) to the (unknown reference) .text.fixup:(unknown)
The fix, as suggested by the warnings, is to add the new .text.fixup
section into the OTHER_TEXT_SECTIONS list.
Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx>
Fixes: 52dc0595d540 ("modpost: handle relocations mismatch in __ex_table")
Fixes: c4a84ae39b4a ("ARM: 8322/1: keep .text and .fixup regions closer together")
---
The mostpost patch has not made it into 4.1 yet, so it's probably best to
add this fix on top of that to avoid breaking when Linus pulls it in.
