The diagram's title is "Storing the thread_info structure and the process kernel stack in two page frames". So its probably referring to physically memory? Further the addresses indicate that this is ZONE_NORMAL in physical memory (Contains page frames of memory at and above 16 MB and below 896 MB). So I think the diagram is alright. -Joel -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
