From 80990c5ba6de9040d2df7c06e3c222c61004085d Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Tue, 23 Aug 2011 17:05:21 -0700 Subject: iommu: No need to set dmar_disabled in check_zero_address() Before the restructruing of the x86 IOMMU code, intel_iommu_init() was getting called directly from pci_iommu_init() and hence needed to explicitly set dmar_disabled to 1 for the failure conditions of check_zero_address(). Recent changes don't call intel_iommu_init() if the intel iommu detection fails as a result of failure in check_zero_address(). So no need for this ifdef and the code inside it.
