+Subject: [PATCH] export: declare ksymtab symbols
+
+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")
