From a6a8e009b118b4906cbb4b382f8cc17195cff860 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 14 Oct 2008 18:25:28 +0000 Subject: [PATCH] powerpc: Silence software timebase sync When no hardware method is provided to sync the timebase registers across the machine, and the platform doesn't sync them for us, then we use a generic software implementation. Currently, the code for that has many printks, and they don't have log levels. Most of the printks are only useful for debugging the code, and since we haven't had any problems with it for years, this turns them into pr_debug.
