This update comes with: * Support for lockless operation in the ARM io-pgtable code. This is an important step to solve the scalability problems in the common dma-iommu code for ARM * Some Errata workarounds for ARM SMMU implemenations * Rewrite of the deferred IO/TLB flush code in the AMD IOMMU driver. The code suffered from very high flush rates, with the new implementation the flush rate is down to ~1% of what it was before * Support for amd_iommu=off when booting with kexec. Problem here was that the IOMMU driver bailed out early without disabling the iommu hardware, if it was enabled in the old kernel * The Rockchip IOMMU driver is now available on ARM64 * Align the return value of the iommu_ops->device_group call-backs to not miss error values * Preempt-disable optimizations in the Intel VT-d and common IOVA code to help Linux-RT * Various other small cleanups and fixes -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJZZgddAAoJECvwRC2XARrjurgQANO338GIBr2ZkA0oectidDpZ Y4yu7W9RH6NyhupJG/Xooya7daBWFjbaA1AVJ3ZZNlMERh69AmehVfRUfVMzF2w+ buma58HQgiJWN1zFD8xdeMzYKms9P77whA88C/9QvrK/klB3LipWP2SC0yvvvyxJ mMCDpgt+D+CGnIDqbRuyLDQoRu3yjAkAvYb6OzL8DPJVP1Y5oLffGwGnHzJbJnOf eWJwYHM5ai0uF/Qqy6RNNekacObjVaOLihjugGvokH6ipXfOrSSNriXW9pZiWR5m S91898YTP3KuWWsJM+N93UAjvc6pL9PqL/OvbB9zdYpzu+5PtUpFXHYcOebKyEEO 4j9CaRzubsWFTFjbYItJnR4WgXQRf4NKOGfTfHMHA+dY8aODYnlXNVdQDAA2aFgn TUBvHq5xb0zZ3nbPwtTDyW06oDMVfBBarLx2yFI1aQSSh+eg/GtIi5KP28gyFZNz 4gWj0q3g/e3y7WEwNbYV7L3TS0d/p8VUYFtUp7PUCddnWoY+4cJzgidub5xIViZD Ql0nZzga9pXXIE/kE5Pf74WqrG7JJzZsvK2ABy4+XGrMq6RclJf+0pXbSqiXDpXL quw8t0oXw0ZEeavQ31Za8mjXBvo5ocM5iintl1wrl2BujHEO3oKqbGsIOaRcLnlN Ukehbl4OEKzZpD3oLPPk =pmBf -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "This update comes with: - Support for lockless operation in the ARM io-pgtable code.
