- * Thread locking implementation for the dynamic linker.
- *
- * We use the "simple, non-scalable reader-preference lock" from:
- *
- *   J. M. Mellor-Crummey and M. L. Scott. "Scalable Reader-Writer
- *   Synchronization for Shared-Memory Multiprocessors." 3rd ACM Symp. on
- *   Principles and Practice of Parallel Programming, April 1991.
- *
- * In this algorithm the lock is a single word.  Its low-order bit is
- * set when a writer holds the lock.  The remaining high-order bits
- * contain a count of readers desiring the lock.  The algorithm requires
- * atomic "compare_and_store" and "add" operations, which we implement
- * using assembly language sequences in "rtld_start.S".
