kgdb/treewide: constify struct kgdb_arch arch_kgdb_ops (2018-12-30 08:33:06 +0000)

----------------------------------------------------------------
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.
