From: Arnd Bergmann <arnd@xxxxxxxx> There are eight architectures using include/uapi/asm-generic/unistd.h, which is still in an old format and not easily parsed by scripts. In addition, arm64 uses the old format for the 32-bit arm compat syscalls, despite them using the modern syscall.tbl format for the native calls. As part of a larger cleanup, this converts all of them to use the new format with a shared file. I was planning to post this earlier, but ended up fixing up any system calls that have mismatched calling conventions between kernel and userspace first, as that seemed more important. I originally tried adding the same arch/*/kernel/syscalls/Makefile as used on the other architectures, but ended up simplifying this in the process to use a single set of Makefile rules in scripts/Makefile.asm-headers, which in turn requires a few cleanups to arch/*/include/asm/Kbuild files. Another prerequisite included in here is to make sys_clone3 get provided on all architectures, though it remains broken and returns -ENOSYS on hexagon, nios2, sh and sparc. To preserve the compile-time warning, I added an explicit #warning for those that are marked broken. Once we have the new table format in place everywhere, additional improvements I have planned will be much easier, including: - generating machine-readable syscall API descriptions for each syscall on each architecture - type checking to ensure that the in-kernel prototype matches what userspace tools see - unifying the last common bits of all tables so that new syscalls only need to get added in one place - generate human-readable wrappers for native and compat syscalls on all architectures to replace the SYSCALL_DEFINEx() macros.
