Howard Mao 04383a31f5 Revert "make sure L2MetadataArray assigns unoccupied way if available" 
This reverts commit 1857f36c1e6f2b2859c724eea6ae3cfb2618f81b.
 2015-11-21 10:35:40 -08:00
Howard Mao 3c95afebc6 Shift set index for multi-bank configurations 
Prior to this commit, the L2 cache banks used the lower bits of the
block address as the set index. However, the lower bits are also used to
route addresses to different banks. As a result, in multi-bank
configurations, only a fraction of the sets in each bank could be
accessed. This commit fixes that problem by using the bits ahead of the
bank index as the set index, so that all sets in the cache can be
accessed.
