That interface depends on CONFIG_MEMORY_HOTPLUG. But given to that
dependency list,
128 config MEMORY_HOTPLUG
129 bool "Allow for memory hot-add"
130 depends on SPARSEMEM || X86_64_ACPI_NUMA
131 depends on HOTPLUG && !HIBERNATION && ARCH_ENABLE_MEMORY_HOTPLUG
132 depends on (IA64 || X86 || PPC64 || SUPERH || S390)
that interface is off on *many* systems (i386, x86_64), so we can't rely
on that interface in kexec. I think on POWER it's much more common than
on PC architectures.
