[Xen-devel] [PATCH] Move acpi memory infor definition to public

["Jiang, Yunhong" <yunhong.jiang@xxxxxxxxx>]

This is the updated version based on Konrad's feedback.
Difference with previous submit: 1) Move it to acpi_driver.h, instead of acpi.h 
2) Under CONFIG_ACPI_HOTPLUG_MEMORY ifdef.
Tested with CONFIG_ACPI_HOTPLUG_MEMORY as both module and yes.

--jyh

Move this definition to header file so that it can be used by dom0 memory 
hotadd logic also.
