Add TEST_GEN_MODS_DIR variable for kselftests. It can point to a directory containing kernel modules that will be used by selftest scripts. The modules are built as external modules for the running kernel. As a result they are always binary compatible and the same tests can be used for older or newer kernels. The build requires "kernel-devel" package to be installed. For example, in the upstream sources, the rpm devel package is produced by "make rpm-pkg" The modules can be built independently by make -C tools/testing/selftests/livepatch/ or they will be automatically built before running the tests via make -C tools/testing/selftests/livepatch/ run_tests Note that they are _not_ built when running the standalone tests by calling, for example, ./test-state.sh. Along with TEST_GEN_MODS_DIR, it was necessary to create a new install rule. INSTALL_MODS_RULE is needed because INSTALL_SINGLE_RULE would copy the entire TEST_GEN_MODS_DIR directory to the destination, even the files created by Kbuild to compile the modules. The new install rule copies only the .ko files, as we would expect the gen_tar to work.

Hi Marcos, I would like the doc patch and lib.mk patch separate. If lib.mk needs changes we don't have to touch the doc patch. thanks, -- Shuah
