memblock, mem_hotplug: introduce MEMBLOCK_HOTPLUG flag to mark hotpluggable regions ...
In find_hotpluggable_memory, once we find out a memory region which is
hotpluggable, we want to mark them in memblock.memory. So that we could
control memblock allocator not to allocte hotpluggable memory for the
kernel later.
To achieve this goal, we introduce MEMBLOCK_HOTPLUG flag to indicate the
hotpluggable memory regions in memblock and a function
memblock_mark_hotplug() to mark hotpluggable memory if we find one.
