      staging: binder: Fix ABI for 64bit Android · df24a2ea
      Serban Constantinescu authored
      BC_REQUEST_DEATH_NOTIFICATION and BC_CLEAR_DEATH_NOTIFICATION were
      defined with the wrong structure that did not match the code. Since a
      binder pointer and handle are the same size on 32 bit systems, this
      change does not affect them. The two commands claimed they were using
      struct binder_ptr_cookie but they are using a 32bit handle and a pointer.
      
      The main purpose of this patch is to add the binder_handle_cookie
      struct so the service manager does not have to define its own version
      (libbinder writes one field at a time so it does not use the struct).
      
      On 32bit systems the payload size is the same as the size of struct
      binder_ptr_cookie. On 64bit systems, the size does differ, and the
      ioctl number does change. However, there are no known 64bit users of
      this interface, and any 64bit systems will need the following patch to
      run 32 bit processes anyway, so it is not expected that anyone will
      ship a 64bit system without this change, so this change should not
      affect any existing systems.
