If we stick to mapping it with a single TLB entry, then the next size up is 256K ... which is a pretty big jump. But the code that does the mapping is just about to be changed from a single locked TLB entry to a map-on-tlb-miss version (thanks to Ken Chen). Some small-ish additions to that code would allow an expansion to 128K by mapping each half with a 64K TLB entry on demand. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
