PADDR Attribute (LOAD_SEGMENT only)

The PADDR attribute is used to specify an explicit physical address for the segment. The value specified is set in the p_addr field of the program header corresponding to the segment. By default, the link-editor sets the physical address of segments to 0, as this field has no meaning for user mode objects, and is primarily of interest non-userland objects such as operating system kernels.
