For vr-kernel dumps use the offsets stored in os_info entries for virt to phys address conversion when dump virtual address is to be read, (e.g. vmcoreinfo symbols) using similar method as implemented in crash-utility. It is mainly required for reading "init_uts_ns" symbol and, in case of crashed kdump, "lowcore_ptr" symbol along with a pointers to the lowcore of every CPU.
