Log message:
        Fix a bunch of long standing bugs and performance clear_page issues:
        - Fix prefetch beyond end of page bug
        - Use primary cache CreateDirtyExclusive also on processor with Scache
        - Don't use CreateDirtyExclusive on processors that don't have it
        - Use prefetch on all processors that have a usable prefetch instruction
        - Select prefetch hint at runtime based on the exact processor.
