It's a joy of learning experience.  How VIVT cache with physical TAG
RAM was invented and how ARM11 solves the cache issue.  It'd be
a long story, probably worth of advanced CS course lesson.

(The practical issue for engineers is ARM9 will keep popularity and not
be replaced by ARM11 SoC anytime soon.  I feel thankful for
NetBSD/arm provides a solid ground to stand)
