Commit 147a89bc authored by Linus Torvalds's avatar Linus Torvalds

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)
