You're saying you have apps that rely on being able to dereference the zero page, and _not_ because the processor mode requires it? I thought the vax died long ago.
The apps were written intentionally to exploit being able to use page 0. It's significantly faster (a factor of 10 or more) and simpler (thousands of lines of code that aren't needed) and easier to use (x<==>y versus x<==>(y + k).) With an identity map the hardware already understands the app's abstraction. -- -- fedora-devel-list mailing list fedora-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-devel-list
