	* malloc/thread-m.h (mutex_init, mutex_lock, mutex_trylock,
	mutex_unlock): If not building NPTL, use __libc_maybe_call2 if
	available, otherwise __libc_maybe_call.
	* sysdeps/unix/sysv/linux/x86_64/recv.c: Add support for
	cancellation handling.
	* sysdeps/unix/sysv/linux/x86_64/send.c: Likewise.
