The patch titled
uml: export symbols added by GCC hardened
has been added to the -mm tree. Its filename is
uml-export-symbols-added-by-gcc-hardened.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@xxxxxxxx>
GCC hardened introduces additional symbol refererences (for the canary and
friends), also in modules - add weak export_symbols for them. We already
tested that the weak declaration creates no problem on both GCC's providing
the function definition and on GCC's which don't provide it.
