Ever since commit 45f035ab ("CONFIG_HOTPLUG should be always on"),
it has been basically impossible to build a kernel with CONFIG_HOTPLUG
turned off.  Remove all the remaining references to it.

There have been persistent lockdep RCU splats, indicating that submitters
are not testing with CONFIG_PROVE_RCU.  Add this config option to the list
in Documentation/SubmitChecklist.  Also add CONFIG_DEBUG_OBJECTS_RCU_HEAD
for good measure.

The sleeping inside spinlock detection is actually used
for more general sleeping inside atomic sections
debugging: preemption disabled, rcu read side critical
sections, interrupts, interrupt disabled, etc...

Change the name of the config and its help section to
reflect its more general role.

Add header file requirements.  Compliments of Stephen Rothwell.

Stephen calls this Rule #1, so I put it there, but I didn't want to demote
any of the others in the list, so I made one of them number 2b.

Follow-up to "block: enable by default support for large devices
and files on 32-bit archs".

Rename CONFIG_LBD to CONFIG_LBDAF to:
- allow update of existing [def]configs for "default y" change
- reflect that it is used also for large files support nowadays

We are seeing increasing levels of minor patch style violations in submissions
to the mailing lists as well as making it into the tree.  These detract from
the quality of the submission and cause unnessary work for reviewers.

As a first step package up the current state of the patch style checker and
include it in the kernel tree.  Add instructions suggesting running it on
submissions.  This adds version v0.01 of the checkpatch.pl script.
