From 4c332c3238ab41fa9bc18d6ccb8e8aec1c87a426 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Sat, 15 Mar 2014 13:11:18 -0700 Subject: [IA64] Keep format strings from leaking into printk The buffer being sent to printk has already had format strings resolved. The string should not be reinterpreted again to avoid any unintended format strings from leaking into printk.
