From d3f138106b4b40640dc667f0222fd9f137387b32 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Tue, 23 Aug 2011 17:05:25 -0700 Subject: iommu: Rename the DMAR and INTR_REMAP config options Change the CONFIG_DMAR to CONFIG_INTEL_IOMMU to be consistent with the other IOMMU options. Rename the CONFIG_INTR_REMAP to CONFIG_IRQ_REMAP to match the irq subsystem name. And define the CONFIG_DMAR_TABLE for the common ACPI DMAR routines shared by both CONFIG_INTEL_IOMMU and CONFIG_IRQ_REMAP.
