// it is a good idea to not to try to do this job by yourself and just

// and refreshes the cache.   If RW is zero, the cache is prepared for
// a read access, and one for a write access.  LOCALITY (0..3) indicates
// the temporal locality of the access.   Larger values let the
// accessed addresses more sticky on the cache.

// on the platform.
