Kbuild updates for v6.10

- Avoid 'constexpr', which is a keyword in C23 - Allow 'dtbs_check' and 'dt_compatible_check' run independently of 'dt_binding_check' - Fix weak references to avoid GOT entries in position-independent code generation - Convert the last use of 'optional' property in arch/sh/Kconfig - Remove support for the 'optional' property in Kconfig - Remove support for Clang's ThinLTO caching, which does not work with the .incbin directive - Change the semantics of $(src) so it always points to the source directory, which fixes Makefile inconsistencies between upstream and downstream - Fix 'make tar-pkg' for RISC-V to produce a consistent package - Provide reasonable default coverage for objtool, sanitizers, and profilers - Remove redundant OBJECT_FILES_NON_STANDARD, KASAN_SANITIZE, etc. - Remove the last use of tristate choice in drivers/rapidio/Kconfig - Various cleanups and fixes in Kconfig -----BEGIN PGP SIGNATURE----- iQJJBAABCgAzFiEEbmPs18K1szRHjPqEPYsBB53g2wYFAmZFlGcVHG1hc2FoaXJv eUBrZXJuZWwub3JnAAoJED2LAQed4NsG8voQALC8NtFpduWVfLRj2Qg6Ll/xf1vX 2igcTJEOFHkeqXLGoT8dTDKLEipUBUvKyguPq66CGwVTe2g6zy/nUSXeVtFrUsIa msLTi8FqhqUo5lodNvGMRf8qqmuqcvnXoiQwIocF92jtsFy14bhiFY+n4HfcFNjj GOKwqBZYQUwY/VVb090efc7RfS9c7uwABJSBelSoxg3AGZriwjGy7Pw5aSKGgVYi inqL1eR6qwPP6z7CgQWM99soP+zwybFZmnQrsD9SniRBI4rtAat8Ih5jQFaSUFUQ lk2w0NQBRFN88/uR2IJ2GWuIlQ74WeJ+QnCqVuQ59tV5zw90wqSmLzngfPD057Dv JjNuhk0UyXVtpIg3lRtd4810ppNSTe33b9OM4O2H846W/crju5oDRNDHcflUXcwm Rmn5ho1rb5QVzDVejJbgwidnUInSgJ9PZcvXQ/RJVZPhpgsBzAY9pQexG1G3hviw y9UDrt6KP6bF9tHjmolmtdIes9Pj0c4dN6/Rdj4HS4hIQ/GDar0tnwvOvtfUctNL orJlBsA6GeMmDVXKkR0ytOCWRYqWWbyt8g70RVKQJfuHX7/hGyAQPaQ2/u4mQhC2 aevYfbNJMj0VDfGz81HDBKFtkc5n+Ite8l157dHEl2LEabkOkRdNVcn7SNbOvZmd ZCSnZ31h7woGfNho =D5B/ -----END PGP SIGNATURE----- Merge tag 'kbuild-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild updates from Masahiro Yamada: - Avoid 'constexpr', which is a keyword in C23 - Allow 'dtbs_check' and 'dt_compatible_check' run independently of 'dt_binding_check' - Fix weak references to avoid GOT entries in position-independent code generation - Convert the last use of 'optional' property in arch/sh/Kconfig - Remove support for the 'optional' property in Kconfig - Remove support for Clang's ThinLTO caching, which does not work with the .incbin directive - Change the semantics of $(src) so it always points to the source directory, which fixes Makefile inconsistencies between upstream and downstream - Fix 'make tar-pkg' for RISC-V to produce a consistent package - Provide reasonable default coverage for objtool, sanitizers, and profilers - Remove redundant OBJECT_FILES_NON_STANDARD, KASAN_SANITIZE, etc. - Remove the last use of tristate choice in drivers/rapidio/Kconfig - Various cleanups and fixes in Kconfig * tag 'kbuild-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (46 commits) kconfig: use sym_get_choice_menu() in sym_check_prop() rapidio: remove choice for enumeration kconfig: lxdialog: remove initialization with A_NORMAL kconfig: m/nconf: merge two item_add_str() calls kconfig: m/nconf: remove dead code to display value of bool choice kconfig: m/nconf: remove dead code to display children of choice members kconfig: gconf: show checkbox for choice correctly kbuild: use GCOV_PROFILE and KCSAN_SANITIZE in scripts/Makefile.modfinal Makefile: remove redundant tool coverage variables kbuild: provide reasonable defaults for tool coverage modules: Drop the .export_symbol section from the final modules kconfig: use menu_list_for_each_sym() in sym_check_choice_deps() kconfig: use sym_get_choice_menu() in conf_write_defconfig() kconfig: add sym_get_choice_menu() helper kconfig: turn defaults and additional prompt for choice members into error kconfig: turn missing prompt for choice members into error kconfig: turn conf_choice() into void function kconfig: use linked list in sym_set_changed() kconfig: gconf: use MENU_CHANGED instead of SYMBOL_CHANGED kconfig: gconf: remove debug code ...
