From 91b40c5be84a478e98c0416325844a7f66d0efae Mon Sep 17 00:00:00 2001 From: Blue Swirl Date: Sun, 13 Sep 2009 13:33:05 +0000 Subject: Fix Sparc/Linux host breakage by df70204db53e3611af986f434e74a882bce190ca While i386, x86_64 and Sparc64/OpenBSD still worked after df70204db53e3611af986f434e74a882bce190ca, Sparc32 and Sparc64 Linux hosts broke. Partially revert the commit: make the restored code conditional to !CONFIG_USER_PIE.
