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
