Symbol export whitelist
Before modules were dynamically loaded the boundary between GPL and non-GPL code was implicit because of the separate link domains for each module. With dynamic modules we need an explicit whitelist of core symbols that non-GPL code can link against at runtime without needing to be re-licensed under the GPL. Mark such symbols with __export, so that it is explicitly clear which symbols in the core can be linked against by non-GPL code. Reduce the visibility of symbols in both the core and ldlinux.c32 with -fvisibility=hidden. __export changes the visibility to 'default'. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
