The following series implements rdmavt. This is the rdma verbs transport
software library which will help to solve the problem of code duplication
between hardware drivers when it comes to a verbs implementation.
Rdmavt is basically just another verbs provider and lives in the Infiniband tree
in a new sw directory. It provides a software implementation of the Infiniband
verbs API. More details can be found in the following threads:

This patch series is based on what appears to be the latest branch on Doug's
kernel.org repo (k.o/for-4.4-rc). I can rebase onto something else if needed.
Changes since v1:
Removed driver specific version
Fixed license text to remove copyright and put on top
Return 0 in rvt_map_sg instead of BAD_DMA_AGGRESS
Remove #include of dma.h from dma.c
Update comment about protection domain limit
Remove comment on alternative design for private data
Rename CDR macro to CHECK_DRIVER_OVERRIDE
Change all the stubs to return EOPNOTSUPP
Fix comment style for rvt_query_port
Fix typo in subject
Rename rdi.lk_table to rdi.lkey_table
Rename rvt_sge.m => rvt_sge.cur_map (Sean)
Rename rvt_sge.n => rvt_sge.cur_seg (Sean)
Remove rvt_reg_phys_mr
Drop support for commit 38071a461f0a ("IB/qib: Support the new memory
registration API")
