This version brings a number of new checks, and a number of bug
fixes.  Of note:

  - checks for spacing on round and square bracket combinations
  - loosening of the single statement brace checks, to allow
    them when they contain comments or where other blocks in a
    compound statement have them.
  - parks the multple declaration support
  - allows architecture defines in architecture specific headers

This version brings a number of new checks, fixes for flase
positives, plus a clarification of the output to better guide use.  Of
note:

  - checks for documentation for new __setup calls
  - clearer reporting where braces and parenthesis are involved
  - reports for closing brace and semi-colon spacing
  - reports on unwanted externs

This patch includes an update to the documentation on checkpatch.pl
itself to clarify when it should be used and to indicate that it
is not intended as the final arbitor of style.

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.
