[RFC net-next 00/10] net/smc: get rid of unsafe_global_rkey

[Ursula Braun <ubraun-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>]

The smc code uses the unsafe_global_rkey, exposing all memory for
remote reads and writes once a connection is established.
Here is now a patch series to get rid of unsafe_global_rkey usage.
Main idea is to switch to SG-logic and separate memory regions for RMBs.

Before final submission to the net-Maintainer I would like to get early
feedback from the RDMA-experts, especially for the main patches:
  03/10 net/smc: introduce sg-logic for RMBs
  04/10 net/smc: use separate memory regions for RMBs
  05/10 net/smc: register RMB-related memory region
  10/10 net/smc: synchronize buffer usage with device

Thanks, Ursula
