[PATCH v3 1/7] mm/hotplug: Simplify ARCH_MHP_MEMMAP_ON_MEMORY_ENABLE kconfig

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
