Merge tag 'rdma-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband
InfiniBand/RDMA fixes for 3.3:
- Fix a crash due to a regression (uninitialized refcnt) introduced in
3.2 with XRC support.
- Close race in how ucma reports events when connect fails.
- Process vendor-specific MADs in mlx4 so that eg FDR-10 data rate works.
- Fix regression in qib caused by over-aggressive PCIe tuning.
- Other small fixes for hardware drivers (ipath, nes, qib).
