   4 Subject: [PATCH 330/331] MIPS: Malta: Mark kernel code and kernel data
   5  segments as BOOT_MEM_RAM.
   6
   7 Kexec-tools requires those segments listed as "System RAM" in
   8 /proc/iomem, otherwise, an error message of "Invalid memory segment"
   9 will be emitted when trying to load the ELF kernel image.
