From 34742db8eaf9ff364034f214ee5827701e131d4b Mon Sep 17 00:00:00 2001 From: Jiang Liu Date: Mon, 13 Apr 2015 14:11:41 +0800 Subject: iommu/vt-d: Refine the interfaces to create IRQ for DMAR unit Refine the interfaces to create IRQ for DMAR unit. It's a preparation for converting DMAR IRQ to hierarchical irqdomain on x86. It also moves dmar_alloc_hwirq()/dmar_free_hwirq() from irq_remapping.h to dmar.h. They are not irq_remapping specific.
