Changeset 9071:7526dad15b35
---------------------------
Cache: Fix the LRU policy for classic memory hierarchy

The LRU policy always evicted the least recently touched way, even if it
contained valid data and another way was invalid, as can happen if a block has
been invalidated by coherance.  This can result in caches never warming up even
though they are replacing blocks.  This modifies the LRU policy to move blocks
to LRU position on invalidation.
