When clone3() was introduced, it was not obvious how each architecture deals with setting up the stack and keeping the register contents in a fork()-like system call, so this was left for the architecture maintainers to implement, with __ARCH_WANT_SYS_CLONE3 defined by those that already implement it. Five years later, we still have a few architectures left that are missing clone3(), and the macro keeps getting in the way as it's fundamentally different from all the other __ARCH_WANT_SYS_* macros that are meant to provide backwards-compatibility with applications using older syscalls that are no longer provided by default. Address this by reversing the polarity of the macro, adding an __ARCH_BROKEN_SYS_CLONE3 macro to all architectures that don't already provide the syscall, and remove __ARCH_WANT_SYS_CLONE3 from all the other ones.
