From 601e7f024edbea8018de34c83a7398623214e636 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 8 May 2006 13:38:42 -0700 Subject: [PATCH] Revert "kbuild: fix modpost segfault for 64bit mipsel kernel" This reverts commit c8d8b837ebe4b4f11e1b0c4a2bdc358c697692ed, which caused problems for the x86 build. Quoth Sam: "It was discussed on mips list but apparently the fix was bogus. I will not have time to look into it so mips can carry this local fix until we get a proper fix in mainline."
