mem-hotplug: let memblock skip the hotpluggable memory regions in __next_mem_range()
Let memblock skip the hotpluggable memory regions in __next_mem_range(),
it is used to to prevent memblock from allocating hotpluggable memory
for the kernel at early time. The code is the same as __next_mem_range_rev().
Clear hotpluggable flag before releasing free pages to the buddy
allocator. If we don't clear hotpluggable flag in
free_low_memory_core_early(), the memory which marked hotpluggable flag
will not free to buddy allocator. Because __next_mem_range() will skip
them.
