1186 Since sigset_t no longer fits in a register, we can't pass in the
1187 thread's initial mask so easily. Take this opportunity to simplify
1188 the clone implementation by only accepting a single void* argument.
1190 * linuxthreads/manager.c (__pthread_manager): Put thread vitals
1191 in the thread struct instead of as arguments through clone.
1192 (pthread_start_thread): Look for them there.
1193 * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1194 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
1195 * linuxthreads/pthread.c (pthread_initialize_manager): Revise
