From 6b1ff036d4cde7834ef2f9dbea5747adaaac24e0 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Sat, 14 Feb 2009 04:11:29 -0500 Subject: [PATCH] [IA64] enable setting DMAR on by default The previous commit which introduced the DMAR_DEFAULT_ON setting in drivers/pci/dmar.c neglected to add the ability for ia64 to enable the IOMMU by default. Rectify that mistake, doh!
