v7 had ability to map hotplugged DIMMs below 4Gb, but Gerd suggested to drop
it since it consume precious lowmem for PCI devices. This version maps
DIMM devices beyond above4gb memory. So "dropped support for 32 bit guests"
here means that if it can't handle GPA above 4Gb and 64bit _CRS, it won't have
working memory cold/hot-plug DIMM devices.

That certainly would help management not have to worry about it.
