Subject: [PATCH v2 06/16] iommu/vt-d: move device_domain_info to header
Date: Thu, 5 Oct 2017 16:03:34 -0700 [thread overview]
Message-ID: <1507244624-39189-7-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
In-Reply-To: <1507244624-39189-1-git-send-email-jacob.jun.pan@linux.intel.com>
Allow both intel-iommu.c and dmar.c to access device_domain_info.
Prepare for additional per device arch data used in TLB flush function
