Dave Jones 924d9addb9 list debugging: use WARN() instead of BUG()
Arjan noted that the list_head debugging is BUG'ing when it detects
corruption.  By causing the box to panic immediately, we're possibly
losing some bug reports.  Changing this to a WARN() should mean we at the
least start seeing reports collected at kerneloops.org

Robert P. J. Day e0ce0da9fe lists: remove a redundant conditional definition of list_add()
Remove the conditional surrounding the definition of list_add() from list.h
since, if you define CONFIG_DEBUG_LIST, the definition you will subsequently
pick up from lib/list_debug.c will be absolutely identical, at which point you
can remove that redundant definition from list_debug.c as well.

Dave Jones 8f63fdbbd6 [PATCH] More list debugging context
Print the other (hopefully) known good pointer when list_head debugging
too, which may yield additional clues.

Also fix for 80-columns to win akpm brownie points.

Andrew Morton ab8e92efcf [PATCH] list_del-debug fix
These two BUG_ON()s are redundant and undesired: we're checking for this
condition further on in the function, only better.

Manfred Spraul df89a86463 [PATCH] list_del debug check
A list_del() debugging check.  Has been in -mm for years.  Dave moved
list_del() out-of-line in the debug case, so this is now suitable for
mainline.
