Merge tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband
Pull infiniband updates from Roland Dreier: "First batch of InfiniBand/RDMA changes for the 3.7 merge window: - mlx4 IB support for SR-IOV - A couple of SRP initiator fixes - Batch of nes hardware driver fixes - Fix for long-standing use-after-free crash in IPoIB - Other miscellaneous fixes" This merge also removes a new use of __cancel_delayed_work(), and replaces it with the regular cancel_delayed_work() that is now irq-safe thanks to the workqueue updates. That said, I suspect the sequence in question should probably use "mod_delayed_work()". I just did the minimal "don't use deprecated functions" fixup, though. * tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband: (45 commits) IB/qib: Fix local access validation for user MRs mlx4_core: Disable SENSE_PORT for multifunction devices mlx4_core: Clean up enabling of SENSE_PORT for older (ConnectX-1/-2) HCAs mlx4_core: Stash PCI ID driver_data in mlx4_priv structure IB/srp: Avoid having aborted requests hang IB/srp: Fix use-after-free in srp_reset_req() IB/qib: Add a qib driver version RDMA/nes: Fix compilation error when nes_debug is enabled RDMA/nes: Print hardware resource type RDMA/nes: Fix for crash when TX checksum offload is off RDMA/nes: Cosmetic changes RDMA/nes: Fix for incorrect MSS when TSO is on RDMA/nes: Fix incorrect resolving of the loopback MAC address mlx4_core: Fix crash on uninitialized priv->cmd.slave_sem mlx4_core: Trivial cleanups to driver log messages mlx4_core: Trivial readability fix: "0X30" -> "0x30" IB/mlx4: Create paravirt contexts for VFs when master IB driver initializes mlx4: Modify proxy/tunnel QP mechanism so that guests do no calculations mlx4: Paravirtualize Node Guids for slaves mlx4: Activate SR-IOV mode for IB ...
