[PATCH] memory hotadd fixes: avoid check in acpi
add_memory() does all necessary check to avoid collision. then, acpi layer
doesn't have to check region by itself.
(*) pfn_valid() just returns page struct is valid or not. It returns 0
if a section has been already added even is ioresource is not added.
ioresource collision check in mm/memory_hotplug.c can do more precise
collistion check.
added enabled bit check just for sanity check..
