[PATCH v3 08/17] crash: Extract crash_get_memory_ranges() helper

[Mike Rapoport]

Hi,

> Factor out the crash memory range collection logic from
> crash_prepare_headers() into a separate function. This allows
> the memory hotplug path to obtain and modify the range list
> (e.g. remove offlined memory) before generating the elfcorehdr.

No need for extern here as well.
