    y2038: Remove newstat family from default syscall set · 82b355d1
    Arnd Bergmann authored
    We have four generations of stat() syscalls:
    - the oldstat syscalls that are only used on the older architectures
    - the newstat family that is used on all 64-bit architectures but
      lacked support for large files on 32-bit architectures.
    - the stat64 family that is used mostly on 32-bit architectures to
      replace newstat
    - statx() to replace all of the above, adding 64-bit timestamps among
      other things.
    
    We already compile stat64 only on those architectures that need it,
    but newstat is always built, including on those that don't reference
    it. This adds a new __ARCH_WANT_NEW_STAT symbol along the lines of
    __ARCH_WANT_OLD_STAT and __ARCH_WANT_STAT64 to control compilation of
    newstat. All architectures that need it use an explict define, the
    others now get a little bit smaller, and future architecture (including
    64-bit targets) won't ever see it.
