4 days	kconfig: Fix repeated include selftest expectation	Zhou Yuhang
	The err_repeated_inc test was added with an expected stderr fixture that does not match the diagnostic printed by kconfig. Running "make testconfig" currently fails in that test even though the parser reports the duplicated include correctly: [stderr] Kconfig.inc1:4: error: repeated inclusion of Kconfig.inc3 Kconfig.inc2:3: note: location of first inclusion of Kconfig.inc3 The fixture expects "Repeated" and "Location" with capital letters, but the diagnostic emitted by scripts/kconfig/util.c uses lowercase words. Update the fixture to match the real message.

2026-02-27	kconfig: Error out on duplicated kconfig inclusion	Nicolas Schier
	Let kconfig exit with error on duplicated Kconfig file inclusion. Repeated inclusion of Kbuild files are considered bad-practise with regard to maintenance; and Kconfig language is rich enough that there should be no need for that. If repeated inclusion of Kconfig files is detected, error out with messages like: Kconfig.inc1:4: error: repeated inclusion of Kconfig.inc3 Kconfig.inc2:3: note: location of first inclusion of Kconfig.inc3 While commit f094f8a1b273 ("kconfig: allow multiple inclusion of the same file") introduced detection of recursive inclusions of Kconfig files, it explicitly allowed repeated inclusions, unfortunately w/o reasoning.
