Subject: [PATCH v3 0/3] mm: Fix for movable_node boot option

This patch series are the fix for movable_node boot option
issue which was introduced by commit 124049decbb1 ("x86/e820:
put !E820_TYPE_RAM regions into memblock.reserved").

The commit breaks the option because it changed the memory
gap range to reserved memblock. So, the node is marked as
Normal zone even if the SRAT has Hot pluggable affinity.

First and second patch fix the original issue which the commit
tried to fix, then revert the commit.

Changelog from v2:
 - Change the patch order. The revert patch is moved to the last.
