Alexander Gordeev d38e48563c s390/crash: Do not use VM info if os_info does not have it ... The virtual memory information stored in os_info area is required for creation of the kernel image PT_LOAD program header for kernels since commit a2ec5bec56dd ("s390/mm: uncouple physical vs virtual address spaces"). By contrast, if such information in os_info is absent the PT_LOAD program header should not be created. Currently the proper PT_LOAD program header is created for kernels that contain the virtual memory information, but for kernels without one an invalid header of zero size is created. That in turn leads to stand-alone dump failures. Use OS_INFO_KASLR_OFFSET variable to check whether os_info is present or not (same as crash and makedumpfile tools do) and based on that create or do not create the kernel image PT_LOAD program header.
