[PATCH v1 1/6] mm/memory_hotplug: remove CONFIG_X86_64_ACPI_NUMA dependency from CONFIG_MEMORY_HOTPLUG

From: David Hildenbrand <hidden>
Date: 2021-09-29 14:37:14
Also in: linux-doc, linux-kselftest, linux-mm, linuxppc-dev, lkml
Subsystem: memory management, memory management - core, the rest · Maintainers: Andrew Morton, David Hildenbrand, Linus Torvalds

SPARSEMEM is the only possible memory model for x86-64, FLATMEM is not
possible:
	config ARCH_FLATMEM_ENABLE
		def_bool y
		depends on X86_32 && !NUMA

And X86_64_ACPI_NUMA (obviously) only supports x86-64:
	config X86_64_ACPI_NUMA
		def_bool y
		depends on X86_64 && NUMA && ACPI && PCI

Let's just remove the CONFIG_X86_64_ACPI_NUMA dependency, as it does no
longer make sense.
