[PATCH] x86: Fix gcc 4.2 _proxy_pda workaround
Due to an over aggressive optimizer gcc 4.2 cannot optimize away _proxy_pda in all cases (counter intuitive, but true). This breaks loading of some modules. The earlier workaround to just export a dummy symbol didn't work unfortunately because the module code ignores exports with 0 value. Make it 1 instead. Signed-off-by: Andi Kleen <ak@suse.de>
