Merge tag 'gcc-plugins-v4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull gcc plugins updates from Kees Cook: "Minor changes to the gcc plugins: - add the gcc plugins Makefile to MAINTAINERS to route things correctly - hide cyc_complexity behind !CONFIG_TEST for the future unhiding of plugins generally" * tag 'gcc-plugins-v4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: gcc-plugins: Adjust Kconfig to avoid cyc_complexity MAINTAINERS: add GCC plugins Makefile
