Eric,
	the major change on the patchset is on the interface, for the v8 emulator,
we accept David's per-node debugfs add_memory interface, we already included
in the documentation patch. the change is very small, so it is not obvious.

This is the change on the documentation compare with v7:
+3) Memory hotplug emulation:
+
+The emulator reserves memory before OS boots, the reserved memory region is
+removed from e820 table. Each online node has an add_memory interface, and
+memory can be hot-added via the per-ndoe add_memory debugfs interface.
+
+The difficulty of Memory Release is well-known, we have no plan for it until
+now.
+
+ - reserve memory thru a kernel boot paramter
+ 	mem=1024m
+
+ - add a memory section to node 3
+    # echo 0x40000000 > mem_hotplug/node3/add_memory
+	OR
+    # echo 1024m > mem_hotplug/node3/add_memory
+
