3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.b...@intel.com>
commit 7b4ec8dd7d4ac467e9eee4d49f2c9574d773efbb upstream.
sparse complains about any __ksymtab symbols with the following:
warning: symbol '__ksymtab_...' was not declared. Should it be static?
due to Andi's patch making it non-static.
Mollify sparse by declaring the symbol extern, otherwise we get
drowned in sparse warnings for anything that uses EXPORT_SYMBOL
in the sources, making it easy to miss real warnings.
Fixes: e0f244c63fc9 ("asmlinkage, module: Make ksymtab [...] __visible")
