[PATCH] iommu/arm-smmu: Delete an unnecessary check before free_io_pgtable_ops()

From: Markus Elfring Date: Fri, 6 Nov 2015 18:32:41 +0100 The free_io_pgtable_ops() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring ---

[PATCH] iommu/vt-d: Add support for multiple DMA aliases

This patch solves IOMMU support issues with PCIe non-transparent bridges that use Requester ID look-up tables (LUT), e.g. PEX8733. Before exiting the bridge, packet's RID is rewritten according to LUT programmed by a driver. Modified packets are then passed to a destination bus and processed upstre
