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

Pull misc kbuild changes from Michal Marek:
 "This is the non-critical part of kbuild for v3.6-rc1:

   - Two new coccinelle semantic patches
   - New scripts/tags.sh regexp
   - scripts/config improvements that I mistakenly applied here instead
     of in the kconfig branch (but there are no conflicts)
   - Debian packaging fixes"

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  scripts/tags.sh: Teach [ce]tags about libtraceeevent error codes
  scripts/coccinelle: list iterator variable semantic patch
  scripts/coccinelle: Find threaded IRQs requests which are missing IRQF_ONESHOT
  deb-pkg: Add all Makefiles to header package
  deb-pkg: Install linux-firmware-image in versioned dir
  scripts/config: add option to undef a symbol
  scripts/config: allow alternate prefix to config option symbol
  scripts/config: add option to not upper-case symbols
