      Q for OS instructors: Why do we lecture on inverted page tables? Is there some system I am unaware of that actually uses this idea?

      @johnregehr I'm guessing you're aware of ppc and sparc/solaris? Are those too obscure enough that you expect students won't have used them?

      @danluu certainly the students will not have used those, and I didn't know they used inverted page tables.

      @johnregehr Just ran across http://yarchive.net/comp/linux/page_tables.html …, which I found interesting. It explains why linux uses page tables for all architectures.

      @johnregehr I'd always wondered about that.
