Subject: [PATCH 1/7] x86: relocate get/set debugreg fcns to
 include/asm/debugreg.

Since we already have a debugreg.h header file, move the
assoc. get/set functions to it.  In addition to it being the
logical home for them, it has a secondary advantage.  The
functions that are moved use BUG().  So we really need to
have linux/bug.h in scope.  But asm/processor.h is used about
600 times, vs. only about 15 for debugreg.h -- so adding bug.h
to the latter reduces the amount of time we'll be processing
it during a compile.

Subject: [PATCH 2/7] spinlock: macroize assert_spin_locked to avoid bug.h
 dependency

In spinlock_api_smp.h we find a define for assert_raw_spin_locked
[which uses BUG_ON].   Then assert_spin_locked (as an inline) uses
it, meaning we need bug.h  But rather than put linux/bug.h in such
a highly used file like spinlock.h, we can just make the un-raw
version also a macro.  Then the required bug.h presence is limited
just to those few files who are actually doing the assert testing.

Subject: [PATCH 3/7] lib: fix implicit users of kernel.h for TAINT_WARN

A pending header cleanup will cause this to show up as:

lib/average.c:38: error: 'TAINT_WARN' undeclared (first use in this function)
lib/list_debug.c:24: error: 'TAINT_WARN' undeclared (first use in this function)

and TAINT_WARN comes from include/linux/kernel.h file.

Subject: [PATCH 4/7] bug.h: add include of it to various implicit C users

With bug.h currently living right in linux/kernel.h there
are files that use BUG_ON and friends but are not including
the header explicitly.  Fix them up so we can remove the
presence in kernel.h file.

From 187f1882b5b0748b3c4c22274663fdb372ac0452 Mon Sep 17 00:00:00 2001
From: Paul Gortmaker <paul.gortmaker@windriver.com>
Date: Wed, 23 Nov 2011 20:12:59 -0500
Subject: [PATCH 5/7] BUG: headers with BUG/BUG_ON etc. need linux/bug.h

If a header file is making use of BUG, BUG_ON, BUILD_BUG_ON, or any
other BUG variant in a static inline (i.e. not in a #define) then
that header really should be including <linux/bug.h> and not just
expecting it to be implicitly present.

We can make this change risk-free, since if the files using these
headers didn't have exposure to linux/bug.h already, they would have
been causing compile failures/warnings.

Subject: [PATCH 6/7] bug: consolidate BUILD_BUG_ON with other bug code

The support for BUILD_BUG in linux/kernel.h predates the
addition of linux/bug.h -- with this chunk off separate,
you can run into situations where a person gets a compile
fail even when they've included linux/bug.h, like this:

    CC      lib/string.o
  lib/string.c: In function 'strlcat':
  lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON'
  make[2]: *** [lib/string.o] Error 1
  $
  $ grep linux/bug.h lib/string.c
  #include <linux/bug.h>
  $

Since the above violates the principle of least surprise, move
the BUG chunks from kernel.h to bug.h so it is all together.

Subject: [PATCH 7/7] kernel.h: doesn't explicitly use bug.h, so don't include
 it.

This header isn't using bug.h infrastructure, but due to historical
reasons, it was including it.  Removing it revealed several implicit
dependencies (since kernel.h is everywhere) so we've fixed those 1st
before deploying this change.
