Update.

* sysdeps/x86_64/pthreaddef.h: New file.

	* sysdeps/i386/pthreaddef.h (gettid): Removed.

	* sysdeps/x86_64/pthread_spin_init.c: New file.
	* sysdeps/x86_64/pthread_spin_lock.c: New file.
	* sysdeps/x86_64/pthread_spin_trylock.c: New file.
	* sysdeps/x86_64/pthread_spin_unlock.c: New file.

	* sysdeps/i386/i686/pthread_spin_trylock.S (pthread_spin_trylock):
	Add missing lock prefix.  Minute optimization.

	* tst-spin2.c (main): Also check successful trylock call.

	* sysdeps/pthread/pthread_sigmask.c (pthread_sigmask): Use correct
	syscall.  Fix typo in case INTERNAL_SYSCALL is not used.

	* sysdeps/i386/pthread_spin_destroy.c: Moved to...
	* sysdeps/pthread/pthread_spin_destroy.c: ...here.  New file.

	* sysdeps/i386/pthread_sigmask.c: Removed.  Use the generic code.
	* sysdeps/pthread/pthread_sigmask.c (pthread_sigmask): Return correct
	value in case of an error.  Add support for INTERNAL_SYSCALL.
