Yes and that is hard wired to the memory hotplug code. It is not easy to
make it work outside of section units

When hot-removing memory release_mem_region_adjustable() splits
iomem resources if they are not the exact size of the memory being
hot-deleted. Adding this memory back to the kernel adds a new
resource.
Eg a node has memory 0x0 - 0xf. Offlining and hot-removing
1GB from 0xf4000
When hot-removing memory release_mem_region_adjustable() splits
iomem resources if they are not the exact size of the memory being
hot-deleted. Adding this memory back to the kernel adds a new
resource.
Eg a node has memory 0x0 - 0xf. Offlining and hot-removing
