Merge branch 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

Pull misc kbuild changes from Michal Marek:
 "The non-critical part of kbuild for 3.5 includes

   - two new coccinelle checks
   - fix for make deb-pkg to include generated headers in arch/*/include

  I have more make-deb-pkg fixes in the backlog, but these will likely
  have to wait for 3.6."

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  builddeb: include autogenerated header files
  scripts/coccinelle: sizeof of pointer
  scripts/coccinelle: address test is always true
