Linus, please pull from
master.kernel.org:/pub/scm/linux/kernel/git/roland/infiniband.git for-linus
This tree is also available from kernel.org mirrors at:
git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git for-linus
This will get various post-rc1 cleanups and fixes:
Adrian Bunk (2):
IB/mthca: Make 2 functions static
RDMA/cxgb3: cleanups
Michael S. Tsirkin (1):
IPoIB/cm: Improve small message bandwidth
Roland Dreier (3):
IPoIB: Remove unused local_rate tracking
IB/uverbs: Return correct error for invalid PD in register MR
IPoIB: Correct debugging output when path record lookup fails
Sean Hefty (4):
IB/core: Set hop limit in ib_init_ah_from_wc correctly
RDMA/cma: Request reversible paths only
IB/cm: Remove ca_guid from cm_device structure
RDMA/cma: Remove unused node_guid from cma_device structure
Steve Wise (1):
RDMA/cxgb3: Stop the EP Timer on BAD CLOSE
