Subject: 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.
