Why is this memory region not marked Guarded? It would seem to meet the definition of “non-well-behaved”.
Why do you think this is the case?
Also the TLB entry for SDRAM marks it Guarded, but that’s one area I would think wouldn't need to be Guarded.
This could be a mistake. Should work without G bis set too. Please give it a try and send a patch to fix it, if it works fine.
Thanks.
