    [AVR32] Add TIF_RESTORE_SIGMASK to the work masks
    
    We really need to check TIF_RESTORE_SIGMASK before returning to
    userspace. The existing code does not necessarily do this.
    
    Define the work masks as a bitwise OR of the respective flags instead
    of a hardcoded hex value to make it easier to spot errors like this in
    the future.
