This is breaking the build in -next on at least arm64 and x86_64 since it's trying to build an out of tree kernel module which is included in the selftests directory, the kselftest build system just isn't set up to do that in a sensible and robust fashion. The module should probably be in the main kernel tree and enabled by the config file for the mm tests. KernelCI sees: *** *** Configuration file ".config" not found! *** *** Please run some configurator (e.g. "make oldconfig" or *** "make menuconfig" or "make xconfig"). *** Makefile:810: include/config/auto.conf.cmd: No such file or directory (see https://storage.kernelci.org/next/master/next-20241114/x86_64/x86_64_defconfig%2Bkselftest/gcc-12/logs/kselftest.log) and I've seen: ERROR: Kernel configuration is invalid. include/generated/autoconf.h or include/config/auto.conf are missing. Run 'make oldconfig && make prepare' on kernel src to fix it. make[3]: *** [Makefile:788: include/config/auto.conf] Error 1
