Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma updates from Doug Ledford: - a large cleanup of how device capabilities are checked for various features - additional cleanups in the MAD processing - update to the srp driver - creation and use of centralized log message helpers - add const to a number of args to calls and clean up call chain - add support for extended cq create verb - add support for timestamps on cq completion - add support for processing OPA MAD packets * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (92 commits) IB/mad: Add final OPA MAD processing IB/mad: Add partial Intel OPA MAD support IB/mad: Add partial Intel OPA MAD support IB/core: Add OPA MAD core capability flag IB/mad: Add support for additional MAD info to/from drivers IB/mad: Convert allocations from kmem_cache to kzalloc IB/core: Add ability for drivers to report an alternate MAD size.
