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

…mmarek/kbuild

Pull kbuild misc updates from Michal Marek:

 - one new coccinelle check and improvements to irqf_oneshot.cocci

 - 'make rpm' POSIX compatibility fix

 - 'make deb-pkg' arm64 cross-compiling fix. I forgot to send this one
   during the v4.9 rc-phase, therefor the pull request is based on -rc6
   and not -rc1

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  Coccinelle: misc: Add support for devm variant in all modes
  Coccinelle: misc: Improve the result given by context mode
  Coccinelle: misc: Improve the matching of rules
  kbuild/mkspec: avoid using brace expansion
  Coccinelle: Add misc/boolconv.cocci
  builddeb: fix cross-building to arm64 producing host-arch debs
