This is better. But allowing access to region 6 through /dev/kmem will open up a whole new set of problems. If the user does an uncacheable read through region 6 from a memory address that is mapped cacheably in region 7, then the processor may machine check [SDM 4.4.1, page 2:64, last paragraph: "It is recommended that the processor report a Machine Check abort if the following memory attribute aliasing is detected: * cache-hit on an uncacheable page"]
So I think we should disallow access to region 6. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
