From fb0a9d7e865afdae70829a64bb004a74ff67d29f Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 5 Jan 2011 12:47:39 +0100 Subject: [S390] pfault: delay register of pfault interrupt Use an early init call to initialize pfault. That way it is possible to use the register_external_interrupt() instead of the early variant. No need to enable pfault any earlier since it has only effect if user space processes are running.
