  The Ultimate Solution To Illegal Virtual Aliases.
  It is better to avoid them completely than to fight them.
  Switch the sparc64 port to 16K pages. The TLBs and TSBs
  continue to operate with 8K pages only. Page tables and
  other generic parts operate with 16K pages.
  
  Because the MMU doesn't support 16K directly, each 16K
  page is emulated by a pair of 8K pages. With 16K pages,
  illegal aliases cannot be created in 16K D-cache.
