From 71b6f2dda824d044242145db8dc10c2037242899 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Fri, 5 Nov 2021 13:44:20 -0700 Subject: [PATCH] mm/memory_hotplug: remove CONFIG_X86_64_ACPI_NUMA dependency from CONFIG_MEMORY_HOTPLUG Patch series "mm/memory_hotplug: Kconfig and 32 bit cleanups". Some cleanups around CONFIG_MEMORY_HOTPLUG, including removing 32 bit leftovers of memory hotplug support. This patch (of 6): 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.
