Merge changes from mainline Hurd. Update L4 bits to compile with those changes. * sysdeps/l4/pt-block.c (__pthread_block): Call l4_receive, not L4_Receive. * sysdeps/l4/pt-create-np.c (pthread_create_from_l4_tid_np): Don't pass TID to __pthread_create_internal. Emit a warning. * sysdeps/l4/pt-stack-alloc.c (allocate_page): Remove function. (__pthread_stack_alloc): Don't require that STACKSIZE is equal to __pthread_stacksize. Call mmap. * sysdeps/l4/pt-thread-halt.c (__pthread_thread_halt): Take additional argument, need_dealloc. Call __pthread_dealloc. Stop the thread. * sysdeps/l4/hurd/pt-sysdep.c (init_routine): When calling __pthread_create_internal, don't pass the tid. * tests/test-1.c (main): Use pthread_mutex_init, not PTHREAD_MUTEX_INITIALIZER. * pthread/pt-alloc.c: Don't include <bits/atomic.h>. Include <atomic.h>. (__pthread_free_threads): Make it an atomicptr_t, not an __atomicptr_t. (__pthread_alloc): Don't use __atomicptr_compare_and_swap, use atomic_compare_and_exchange_val_acq. * pthread/pt-create.c: Don't include <bits/atomic.h>. Include <atomic.h>. (__pthread_total): Make it an atomic_fast32_t, not an __atomic_t. (__pthread_create_internal): Use atomic_increment and atomic_decrement, not __atomic_inc and __atomic_dec. * pthread/pt-dealloc.c: Don't include <bits/atomic.h>. Include <atomic.h>. (__pthread_free_threads): Make it an atomicptr_t, not an __atomicptr_t. (__pthread_dealloc): Use atomic_compare_and_exchange_val_acq, not __atomicptr_compare_and_swap. * pthread/pt-exit.c: Don't include <bits/atomic.h>. Include <atomic.h>. (pthread_exit): Use atomic_decrement_and_test, not __atomic_dec_and_test. * pthread/pt-internal.h: Don't include <bits/atomic.h>. Include <atomic.h>. (__pthread_total): Make it an atomic_fast32_t, not an __atomic_t. * sysdeps/powerpc/bits/atomic.h: Remove file. * sysdeps/ia32/bits/atomic.h: Likewise.
