671 Since sigset_t no longer fits in a register, we can't pass in the
672 thread's initial mask so easily. Take this opportunity to simplify
673 the clone implementation by only accepting a single void* argument.
675 * linuxthreads/manager.c (__pthread_manager): Put thread vitals
676 in the thread struct instead of as arguments through clone.
677 (pthread_start_thread): Look for them there.
678 * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
679 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
680 * linuxthreads/pthread.c (pthread_initialize_manager): Revise
