v4: Incorporated feedback:
    - no changes for this arch
v3: Incorporated feedback:
    - changes for coding convention and formatting
    - restructured to introduce get_crash_kernel_load_range() for each
      architecture, and then a single function in kexec/kexec.c to call
      the per-architecture get_crash_kernel_load_range() and print the
      result.
    - print_crashkernel_region_size() changed to get_crash_kernel_load_range()
v2: Incorporated feedback:
    - no changes for this arch
v1: Posted to kexec-tools mailing list
