From bf3647c44bc76c43c4b2ebb4c37a559e899ac70e Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 29 Jan 2009 11:45:35 +0100 Subject: [PATCH] x86: tone down mtrr_trim_uncached_memory() warning kerneloops.org is reporting a lot of these warnings that come due to vmware not setting up any MTRRs for emulated CPUs: | Reported 709 times (14696 total reports) | BIOS bug (often in VMWare) where the MTRR's are set up incorrectly | or not at all | | This warning was last seen in version 2.6.29-rc2-git1, and first | seen in 2.6.24. | | More info: | http://www.kerneloops.org/searchweek.php?search=mtrr_trim_uncached_memory Keep a one-liner KERN_INFO about it - so that we have so notice if empty MTRRs are caused by native hardware/BIOS weirdness.
