From 08269c6d38e003adb12f55c6d795daa89bdc1bae Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 16 Apr 2007 10:30:27 +0200 Subject: [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.
