5 first patches are relatively small iommu fixes/cleanups. 2 last patches are proposals for core iommu extensions: - Add fault report mechanism, needed for recovery of remote processors trying to access unmapped addresses. - Add splitting of memory regions to pages in the iommu core itself (according to hardware capabilities as advertised by the iommu drivers). This is needed to prevent duplication of this logic by the iommu users/drivers themselves. The patches are based on Joerg's arm/omap branch. Tested with OMAP3 (omap3isp) + OMAP4 (rpmsg/remoteproc). Laurent Pinchart (1): iommu/omap-iovmm: support non page-aligned buffers in iommu_vmap Ohad Ben-Cohen (6): iommu/omap: cleanup: remove a redundant 'return' statement iommu/core: use the existing IS_ALIGNED macro iommu/omap: ->unmap() should return order of unmapped page iommu/msm: ->unmap() should return order of unmapped page iommu/core: add fault reporting iommu/core: split mapping to page sizes as supported by the hardware arch/arm/plat-omap/include/plat/iommu.h | 3 +- drivers/iommu/iommu.c | 142 +++++++++++++++++++++++++++---- drivers/iommu/msm_iommu.c | 15 +++- drivers/iommu/omap-iommu.c | 56 +++--------- drivers/iommu/omap-iovmm.c | 50 +++++++----- drivers/media/video/omap3isp/isp.c | 2 +- include/linux/iommu.h | 67 ++++++++++++++- virt/kvm/iommu.c | 6 +- 8 files changed, 251 insertions(+), 90 deletions(-) -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
