From bebfa1013eee1d91b3242e5801cc8fbdfaf148ec Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 26 Jun 2006 13:56:52 +0200 Subject: [PATCH] x86_64: Add compat_printk and sysctl to turn off compat layer warnings Sometimes e.g. with crashme the compat layer warnings can be noisy. Add a way to turn them off by gating all output through compat_printk that checks a global sysctl. The default is not changed.
