       "This contains a series of patches to fix CLONE_SETTLS when used with
        clone3().
      
        The clone3() syscall passes the tls argument through struct clone_args
        instead of a register. This means, all architectures that do not
        implement copy_thread_tls() but still support CLONE_SETTLS via
        copy_thread() expecting the tls to be located in a register argument
        based on clone() are currently unfortunately broken. Their tls value
        will be garbage.
      
        The patch series fixes this on all architectures that currently define
        __ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure
        that any architecture that enables clone3() in the future is forced to
        also implement copy_thread_tls().
      
        My ultimate goal is to get rid of the copy_thread()/copy_thread_tls()
        split and just have copy_thread_tls() at some point in the not too
        distant future (Maybe even renaming copy_thread_tls() back to simply
        copy_thread() once the old function is ripped from all arches). This
        is dependent now on all arches supporting clone3().
      
        While all relevant arches do that now there are still four missing:
        ia64, m68k, sh and sparc. They have the system call reserved, but not
        implemented. Once they all implement clone3() we can get rid of
        ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS.
      
        This series also includes a minor fix for the arm64 uapi headers which
        caused __NR_clone3 to be missing from the exported user headers.
      
        Unfortunately the series came in a little late especially given that
        it touches a range of architectures. Due to the holidays not all arch
        maintainers responded in time probably due to their backlog. Will and
        Arnd have thankfully acked the arm specific changes.
      
        Given that the changes are straightforward and rather minimal combined
        with the fact the that clone3() with CLONE_SETTLS is broken I decided
        to send them post rc3 nonetheless"
