Pull modules updates from Luis Chamberlain: "Nothing exciting at all for modules for v6.3. The biggest change is just the change of INSTALL_MOD_DIR from "extra" to "updates" which I found lingered for ages for no good reason while testing the CXL mock driver [0]. The CXL mock driver has no kconfig integration and requires building an external module... and re-building the *rest* of the production drivers. This mock driver when loaded but not the production ones will crash. All this can obviously be fixed by integrating kconfig semantics into such test module, however that's not desirable by the maintainer, and so sensible defaults must be used to ensure a default "make modules_install" will suffice for most distros which do not have a file like /etc/depmod.d/dist.conf with something like `search updates extra built-in`. Since most distros rely on kmod and since its inception the "updates" directory is always in the search path it makes more sense to use that than the "extra" which only *some* RH based systems rely on. All this stuff has been on linux-next for a while" [0] https://lkml.kernel.org/r/20221209062919.1096779-1-mcgrof@kernel.org * tag 'modules-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: Documentation: livepatch: module-elf-format: Remove local klp_modinfo definition module.h: Document klp_modinfo struct using kdoc module: Use kstrtobool() instead of strtobool() kernel/params.c: Use kstrtobool() instead of strtobool() test_kmod: stop kernel-doc warnings kbuild: Modify default INSTALL_MOD_DIR from extra to updates
