#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
#     
#     Pull rdma fixes from Jason Gunthorpe:
#      "Nothing particularly exciting, some small ODP regressions from the mmu
#       notifier rework, another bunch of syzkaller fixes, and a bug fix for a
#       botched syzkaller fix in the first rc pull request.
#     
#        - Fix busted syzkaller fix in 'get_new_pps' - this turned out to
#          crash on certain HW configurations
#     
#        - Bug fixes for various missed things in error unwinds
#     
#        - Add a missing rcu_read_lock annotation in hfi/qib
#     
#        - Fix two ODP related regressions from the recent mmu notifier
#          changes
#     
#        - Several more syzkaller bugs in siw, RDMA netlink, verbs and iwcm
#     
#        - Revert an old patch in CMA as it is now shown to not be allocating
#          port numbers properly"
