Hari Bathini 1a1cf93c20 powerpc/kexec_file: Setup backup region for kdump kernel ... Though kdump kernel boots from loaded address, the first 64KB of it is copied down to real 0. So, setup a backup region and let purgatory copy the first 64KB of crashed kernel into this backup region before booting into kdump kernel. Update reserve map with backup region and crashed kernel's memory to avoid kdump kernel from accidentially using that memory.
