Merge tag 'kconfig-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kconfig updates from Masahiro Yamada: - improve checkpatch for more precise Kconfig code checking - clarify effective selects by grouping reverse dependencies in help - do not write out '# CONFIG_FOO is not set' from invisible symbols - make oldconfig as silent as it should be - rename 'silentoldconfig' to 'syncconfig' - add unit-test framework and several test cases - warn unmet dependency of tristate symbols - make unmet dependency warnings readable, removing false positives - improve recursive include detection - use yylineno to simplify the line number tracking - misc cleanups * tag 'kconfig-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (30 commits) kconfig: use yylineno option instead of manual lineno increments kconfig: detect recursive inclusion earlier kconfig: remove duplicated file name and lineno of recursive inclusion kconfig: do not include both curses.h and ncurses.h for nconfig kconfig: make unmet dependency warnings readable kconfig: warn unmet direct dependency of tristate symbols selected by y kconfig: tests: test if recursive inclusion is detected kconfig: tests: test if recursive dependencies are detected kconfig: tests: test randconfig for choice in choice kconfig: tests: test defconfig when two choices interact kconfig: tests: check visibility of tristate choice values in y choice kconfig: tests: check unneeded "is not set" with unmet dependency kconfig: tests: test if new symbols in choice are asked kconfig: tests: test automatic submenu creation kconfig: tests: add basic choice tests kconfig: tests: add framework for Kconfig unit testing kbuild: add PYTHON2 and PYTHON3 variables kconfig: remove redundant streamline_config.pl prerequisite kconfig: rename silentoldconfig to syncconfig kconfig: invoke oldconfig instead of silentoldconfig from local*config ...
