Linus Torvalds d1f2b1710d IOMMU Updates for Linux v4.20 ... These updates bring: - Debugfs support for the Intel VT-d driver. When enabled, it now also exposes some of its internal data structures to user-space for debugging purposes. - ARM-SMMU driver now uses the generic deferred flushing and fast-path iova allocation code. This is expected to be a major performance improvement, as this allocation path scales a lot better. - Support for r8a7744 in the Renesas iommu driver - Couple of minor fixes and improvements all over the place -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJb0vixAAoJECvwRC2XARrj0lkQALur432cGae8225gLNG+Ab1B lDGz/8uJeV4V552r58msq/yFpVascoMYOCgS+5N5J/jn5UiPnWxk//Uz2lvvCsFn 3Z4HswSbmNLSuEHmN3/1CK28An44LjYxtnH/zAEaHRJgWNmC05lO4glPXaSIBwVS ve6ULymHJittCHFNNAstNBvMYirYV2y+FYxoq6EteTuCruNNXR78KQV7TqPYI+uZ 0DwaXUyxO+HZbVeLpOnj/WHZ6+EUY0cHwHuk8U6ZCHnINZ+k9knt+WUvYu7wPCtj jGIyJXW5BG0rjJZnVUQs9BFXFSJLV2Ap8M3zKVIyFAUAyStEtGHct0YMRC29GX/J e45GPbElAZqx1NWRGGTV0xTsH5Gn85S2nP3p7iiPhj5zUhX/6SreZBDQdC+brtsB 8HG85xohsUkVmRq/ez4hu0yqXtB66ppV7TcOjyixybG+ixRPtUwTbiaYUxbvkZTr hcYUVLGcpJX463VjUKGoRPFL/jZ6BXUWdLVllZPYgDT+IBXtQx1TB20DDtj5V2mR 3m7B0xLQJDWdarhdA9Oj0FQj7ivmwmitcJ9EoNvHSRdEoE1iIy1vHv/7v/GokRVS J1YT5ZYAsGHBgZIsL7FpVA37i9t3JPVvgakUV/ZfLDyG3v+P0+eS3gNhECYt5luS D8G7Jy+2vsitO/ZCyu/r =q1HJ -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: - Debugfs support for the Intel VT-d driver.
