[PATCH v1 0/3] coding-style.rst: document BUG() and WARN() rules

[David Hildenbrand <david@redhat.com>]

As it seems to be rather unclear if/when to use BUG(), BUG_ON(),
VM_BUG_ON(), WARN_ON_ONCE(), ... let's try to document the result of a
recent discussion.

Details can be found in patch #1.

RFC -> v1:
* "coding-style.rst: document BUG() and WARN() rules ("do not crash the
   kernel")"
 -> Rephrase/extend according to John
 -> Add some details regarding the use of panic()
* powerpc/prom_init: drop PROM_BUG()
 -> Added
* "checkpatch: warn on usage of VM_BUG_ON() and other BUG variants"
 -> Warn on more variants
