From cc54c1e66e4b90ab657464fec30e6970636ee23d Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 26 Mar 2009 15:23:59 +0100 Subject: [S390] ftrace: dont trace machine check handler The ftrace code is currently not reentrant, so we better don't trace our machine check handler. Machine checks are handled like NMIs on s390.
