[PATCH v1 0/6] mm/memory_hotplug: Kconfig and 32 bit cleanups

From: David Hildenbrand
Date: Wed Sep 29 2021 - 10:36:50 EST


Some cleanups around CONFIG_MEMORY_HOTPLUG, including removing 32 bit
leftovers of memory hotplug support.

Compile-tested on various architectures, quickly tested memory hotplug
on x86-64.
