v5: Incorporated feedback:
- no changes for this arch
v4: Incorporated feedback:
- Changed commit description to make it clear that
get_crash_kernel_load_range() is a stub
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.
v2: Incorporated feedback:
- unsupported architectures, print appropriate message
