Add IORESOUCE_BUSY flag for System RAM
i386 and x86-64 registers System RAM as IORESOURCE_MEM | IORESOURCE_BUSY. But ia64 registers it as IORESOURCE_MEM only. In addition, memory hotplug code registers new memory as IORESOURCE_MEM too. This difference causes a failure of memory unplug of x86-64. This patch fixes it. This patch adds IORESOURCE_BUSY to avoid potential overlap mapping by PCI device.
