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

Pull kbuild misc updates from Michal Marek:
 "The non-critical part of kbuild for v4.6-rc1:

   - coccinelle cleanup and a new patch
   - make tags rule for kprobe helpers
   - make rpm fix to avoid spurious grub2 entries
   - make rpm support for %postun script (Fedora only at the moment)"

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  kbuild/mkspec: clean boot loader configuration on rpm removal
  kbuild/mkspec: fix grub2 installkernel issue
  Coccinelle: Add api/setup_timer.cocci
  coccinelle: bugon: reduce rule applicability
  Coccinelle: pm_runtime: reduce rule applicability
  Coccinelle: array_size: reduce rule applicability
  Coccinelle: reduce rule applicability
  scripts/tags.sh: add regex to map kprobe helpers
  scripts/coccinelle: modernize &
