The patch titled
uml: export symbols added by GCC hardened
has been removed from the -mm tree. Its filename is
uml-export-symbols-added-by-gcc-hardened.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
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.
