	* elf/dl-runtime.c: Include sysdep-cancel.h.
	(_dl_fixup, _dl_profile_fixup): Use __rtld_mrlock_* and

	instead of catomic_* macros.
	* elf/dl-sym.c: Include sysdep-cancel.h.
	(do_sym): Use __rtld_mrlock_* and scoperec->nusers only
	if !SINGLE_THREAD_P.  Use atomic_* instead of catomic_* macros.
	* elf/dl-close.c: Include sysdep-cancel.h.
	(_dl_close): Use __rtld_mrlock_* and scoperec->nusers only

	* sysdeps/i386/i486/bits/atomic.h (catomic_decrement): Use correct
	body macro.
	* sysdeps/x86_64/bits/atomic.h
	(__arch_c_compare_and_exchange_val_64_acq): Add missing casts.
