From 50005a8deb38e5e6456ebd94e57adb321d4589de Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 12 Nov 2010 13:04:16 +0000 Subject: [PATCH] ARM: module: ignore unwind for sections not marked SHF_ALLOC If a section is not marked with SHF_ALLOC, it will be discarded by the module code. Therefore, it is not correct to register the unwind tables.
