Current acpi memory hotplug just looks into the first entry of resources in _CRS. But, _CRS can contain plural resources. So, if _CRS contains plural resoureces, acpi memory hot add cannot add all memory. With this patch, acpi memory hotplug can deal with Memory Device, whose _CRS contains plural resources. Tested on ia64 memory hotplug test envrionment (not emulation, uses alpha version firmware which supports dynamic reconfiguration of NUMA.) Note: Microsoft's Windows Server 2003 requires big (>4G)resoureces to be divided into small (<4G) resources. looks crazy, but not invalid. (See http://www.microsoft.com/whdc/system/pnppwr/hotadd/hotaddmem.mspx) For this reason, a firmware vendor who supports Windows writes plural resources in a _CRS even if they are contiguous.
