 385         * linuxtheads/pthread.c (__pthread_initial_thread): Correct
 386         initializer.
 387         (__pthread_manager_thread): Likewise.

 392         Since sigset_t no longer fits in a register, we can't pass in the
 393         thread's initial mask so easily.  Take this opportunity to simplify
 394         the clone implementation by only accepting a single void* argument.
 395
 396         * linuxthreads/manager.c (__pthread_manager): Put thread vitals
 397         in the thread struct instead of as arguments through clone.
 398         (pthread_start_thread): Look for them there.
 399         * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
 400         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
 401         * linuxthreads/pthread.c (pthread_initialize_manager): Revise
 402         clone invocation.
