- * Support "tns" atomic integers.  These are atomic integers that can
- * hold any value but "1".  They are more efficient than regular atomic
- * operations because the "lock" (aka acquire) step is a single "tns"
- * in the uncontended case, and the "unlock" (aka release) step is a
- * single "store" without an mf.  (However, note that on tilepro the
- * "tns" will evict the local cache line, so it's not all upside.)
- *
- * Note that you can ONLY observe the value stored in the pointer
- * using these operations; a direct read of the value may confusingly
- * return the special value "1".
