From b867059018a5254cca14450eefb6fb8effa0f6dd Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Tue, 20 Jun 2017 23:16:37 +0200 Subject: x86/MCE, xen/mcelog: Make /dev/mcelog registration messages more precise When running under Xen as dom0, /dev/mcelog is being provided by Xen instead of the normal mcelog character device of the MCE core. Convert an error message being issued by the MCE core in this case to an informative message that Xen has registered the device.
