4.21 merge window 2nd pull request

Browse Source 
Over the break a few defects were found, so this is a -rc style pull
 request of various small things that have been posted.
 
 - An attempt to shorten RCU grace period driven delays showed crashes
   during heavier testing, and has been entirely reverted
 
 - A missed merge/rebase error between the advise_mr and ib_device_ops
   series
 
 - Some small static analysis driven fixes from Julia and Aditya
 
 - Missed ability to create a XRC_INI in the devx verbs interop series
