Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma fixes from Doug Ledford:
"This has been a slow -rc cycle for the RDMA subsystem. We really
haven't had a lot of rc fixes come in. This pull request is the first
of this entire rc cycle and it has all of the suitable fixes so far
and it's still only about 20 patches. The fix for the minor breakage
cause by the dma mapping patchset is in here, as well as a couple
other potential oops fixes, but the rest is more minor.
Summary:
- fix for dma_ops change in this kernel, resolving the s390, powerpc,
and IOMMU operation
- a few other oops fixes
- the rest are all minor fixes"
