Subject: [PATCH char-misc-next 1/1] misc: mic: Fix SCIF build failure with IOMMU_SUPPORT disabled
Date: Sun, 4 Oct 2015 13:38:40 -0700 [thread overview]
Message-ID: <0b823b9b5ac6420f374fd15d8e97b313d833cc7b.1443990982.git.sudeep.dutt@intel.com> (raw)
SCIF depends on IOVA which requires IOMMU_SUPPORT to be enabled.
The long term fix is to move IOVA from drivers/iommu to lib/
but this current patch should fix the reported issue.
