From 09e56a2d076c2afb2a1932ae4283e10ef2d26ef3 Mon Sep 17 00:00:00 2001 From: Phil Carmody Date: Thu, 19 Aug 2010 15:19:04 +0100 Subject: ARM: 6340/1: module - additional unwind tables for exit/devexit sections Without these, exit functions cannot be stack-traced, so to speak. This implies that module unloads that perform allocations (don't laugh) will cause noisy warnings on the console when kmemleak is enabled, as it presumes that all code's call chains are traceable. Similarly, BUGs and WARN_ONs will give additional console spam.
