-/* ================================ CACHE LOCKING============================
- *
- * The XScale MicroArchitecture implements support for locking entries into
- * the data and instruction cache.  The following functions implement the core
- * low level instructions needed to accomplish the locking.  The developer's
- * manual states that the code that performs the locking must be in non-cached
- * memory.  To accomplish this, the code in xscale-cache-lock.c copies the
- * following functions from the cache into a non-cached memory region that
- * is allocated through consistent_alloc().
