Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull main rdma updates from Doug Ledford:
"This is the main pull request for the rdma stack this release. The
code has been through 0day and I had it tagged for linux-next testing
for a couple days.
Summary:
- updates to mlx5
- updates to mlx4 (two conflicts, both minor and easily resolved)
- updates to iw_cxgb4 (one conflict, not so obvious to resolve,
proper resolution is to keep the code in cxgb4_main.c as it is in
Linus' tree as attach_uld was refactored and moved into
cxgb4_uld.c)
- improvements to uAPI (moved vendor specific API elements to uAPI
area)
- add hns-roce driver and hns and hns-roce ACPI reset support
- conversion of all rdma code away from deprecated
create_singlethread_workqueue
- security improvement: remove unsafe ib_get_dma_mr (breaks lustre in
staging)"
