Content-Type: text/plain; charset=ISO-8859-1; format=flowed List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Is there a good source that lists the standard virtual address mappings of the various components of linux? I know the kernel starts at 0xC000_0000 and user apps start at 0x1000_0000, but things like shared objects are much less clear. For example, the smap entry for my ntpd process shows two distinct areas of usage: ~0xf000_0000 and ~0x3000_0000, but I have no idea what's where and why. Can anyone shed some light on this? Thanks.
