625 Since sigset_t no longer fits in a register, we can't pass in the
626 thread's initial mask so easily. Take this opportunity to simplify
627 the clone implementation by only accepting a single void* argument.
629 * linuxthreads/manager.c (__pthread_manager): Put thread vitals
630 in the thread struct instead of as arguments through clone.
631 (pthread_start_thread): Look for them there.
632 * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
633 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
634 * linuxthreads/pthread.c (pthread_initialize_manager): Revise
