Aneesh Kumar K.V 1a8c64e110 mm/memory_hotplug: embed vmem_altmap details in memory block
With memmap on memory, some architecture needs more details w.r.t altmap
such as base_pfn, end_pfn, etc to unmap vmemmap memory.  Instead of
computing them again when we remove a memory block, embed vmem_altmap
details in struct memory_block if we are using memmap on memory block
feature.
