Eventually, once the build succeeds on a sufficiently old distro, the idea is to delete $(KHDR_INCLUDES) from the selftests/mm build, and then after that, from selftests/lib.mk and all of the other selftest builds. For now, this series merely achieves a clean build of selftests/mm on a not-so-old distro: Ubuntu 23.04. In other words, after this series is applied, it is possible to delete $(KHDR_INCLUDES) from selftests/mm/Makefile and the build will still succeed. 1. Add tools/uapi/asm/unistd_[32|x32|64].h files, which include definitions of __NR_mseal, and include them (indirectly) from the files that use __NR_mseal. The new files are copied from ./usr/include/asm, which is how we have agreed to do this sort of thing, see [1]. 2. Add fs.h, similarly created: it was copied directly from a snapshot of ./usr/include/linux/fs.h after running "make headers". 3. Add a few selected prctl.h values that the ksm and mdwe tests require. 4. Factor out some common code from mseal_test.c and seal_elf.c, into a new mseal_helpers.h file. 5. Remove local __NR_* definitions and checks. [1] commit e076eaca5906 ("selftests: break the dependency upon local header files") This patch (of 6): The selftests/mm build isn't exactly "broken", according to the current documentation, which still claims that one must run "make headers", before building the kselftests. However, according to the new plan to get rid of that requirement [1], they are future-broken: attempting to build selftests/mm *without* first running "make headers" will fail due to not finding __NR_mseal. Therefore, include asm-generic/unistd.h, which has all of the system call numbers that are needed, abstracted across the various CPU arches.
