mm/memory_hotplug: simplify ARCH_MHP_MEMMAP_ON_MEMORY_ENABLE kconfig
Patch series "Add support for memmap on memory feature on ppc64", v8.
This patch series update memmap on memory feature to fall back to
memmap allocation outside the memory block if the alignment rules are
not met. This makes the feature more useful on architectures like
ppc64 where alignment rules are different with 64K page size.
This patch (of 6):
Instead of adding menu entry with all supported architectures, add
mm/Kconfig variable and select the same from supported architectures.
No functional change in this patch.
