Linus Torvalds fcf010449e kgdb patches for 4.20-rc1 
Mostly clean ups although whilst Doug's was chasing down a odd
 lockdep warning he also did some work to improved debugger resilience
 when some CPUs fail to respond to the round up request.
 
 The main changes are:
 
  * Fixing a lockdep warning on architectures that cannot use an NMI for
    the round up plus related changes to make CPU round up and all CPU
    backtrace more resilient.
 
  * Constify the arch ops tables
 
  * A couple of other small clean ups
 
 Two of the three patchsets here include changes that spill over into
 arch/.  Changes in the arch space are relatively narrow in scope
 (and directly related to kgdb). Didn't get comprehensive acks but
 all impacted maintainers were Cc:ed in good time.
