Merge tag 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull second round of rdma updates from Doug Ledford:
"This can be split out into just two categories:
- fixes to the RDMA R/W API in regards to SG list length limits
(about 5 patches)
- fixes/features for the Intel hfi1 driver (everything else)
The hfi1 driver is still being brought to full feature support by
Intel, and they have a lot of people working on it, so that amounts to
almost the entirety of this pull request"
