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@arndb.de> 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. -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
