From 8b132ecbcfea8b1b556a832df7290379df79ad79 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 28 Apr 2008 02:51:23 +0200 Subject: [PATCH] x86: fix text_poke() kernel_text_address returns true even for modules which is not wanted in text_poke. Use core_kernel_text instead. This is a regression introduced in e587cadd8f47e202a30712e2906a65a0606d5865 which caused occasionaly crashes after suspend/resume.
