[PATCH v7 4/9] crash_core: replace for_each_mem_range() with for_each_mem_region()

[sashiko-bot at kernel.org]

> From: Wandun Chen <chenwandun at lixiang.com>
> 
> for_each_mem_range() skips MEMBLOCK_NOMAP regions implicitly. Switch the
> weak defaults to for_each_mem_region(), which exposes struct
> memblock_region and per-region flags, and filter NOMAP regions explicitly
> via the new crash_should_skip_region() helper. This prepares for a
> subsequent patch to extend the skip filter.
> 
> No functional change.
> 
> Signed-off-by: Wandun Chen <chenwandun at lixiang.com>
