Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "This has been a smaller cycle than normal. One new driver was accepted, which is unusual, and at least one more driver remains in review on the list. Summary: - Driver fixes for hns, hfi1, nes, rxe, i40iw, mlx5, cxgb4, vmw_pvrdma - Many patches from MatthewW converting radix tree and IDR users to use xarray - Introduction of tracepoints to the MAD layer - Build large SGLs at the start for DMA mapping and get the driver to split them - Generally clean SGL handling code throughout the subsystem - Support for restricting RDMA devices to net namespaces for containers - Progress to remove object allocation boilerplate code from drivers - Change in how the mlx5 driver shows representor ports linked to VFs - mlx5 uapi feature to access the on chip SW ICM memory - Add a new driver for 'EFA'. This is HW that supports user space packet processing through QPs in Amazon's cloud" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (186 commits) RDMA/ipoib: Allow user space differentiate between valid dev_port IB/core, ipoib: Do not overreact to SM LID change event RDMA/device: Don't fire uevent before device is fully initialized lib/scatterlist: Remove leftover from sg_page_iter comment RDMA/efa: Add driver to Kconfig/Makefile RDMA/efa: Add the efa module RDMA/efa: Add EFA verbs implementation RDMA/efa: Add common command handlers RDMA/efa: Implement functions that submit and complete admin commands RDMA/efa: Add the ABI definitions RDMA/efa: Add the com service API definitions RDMA/efa: Add the efa_com.h file RDMA/efa: Add the efa.h header file RDMA/efa: Add EFA device definitions RDMA: Add EFA related definitions RDMA/umem: Remove hugetlb flag RDMA/bnxt_re: Use core helpers to get aligned DMA address RDMA/i40iw: Use core helpers to get aligned DMA address within a supported page size RDMA/verbs: Add a DMA iterator to return aligned contiguous memory blocks RDMA/umem: Add API to find best driver supported page size in an MR ...
