In load_crashdump_segments(), memmap_p used to contain RANGE_RAM memory range for booting 2nd kernel. Now adding types of RANGE_ACPI and RANGE_ACPI_NVS to memmap_p, so later we can pass all the types of memory range to 2nd kernel. These all types of memory ranges are all stored in memmap_p. I'll add above comment to patch description.
