1165 Since sigset_t no longer fits in a register, we can't pass in the
1166 thread's initial mask so easily. Take this opportunity to simplify
1167 the clone implementation by only accepting a single void* argument.
1169 * linuxthreads/manager.c (__pthread_manager): Put thread vitals
1170 in the thread struct instead of as arguments through clone.
1171 (pthread_start_thread): Look for them there.
1172 * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1173 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
1174 * linuxthreads/pthread.c (pthread_initialize_manager): Revise
