[Qemu-devel] [PATCH 8/11] fixup! pc: align DIMM's address/size by backend's alignment value

[Igor Mammedov <imammedo@redhat.com>]

Performance wise it's better to align GVA by the backend's
page size.

Also do not allow to create DIMM device with suboptimal
size (i.e. not aligned to backends page size) to aviod
memory loss.

Do above only for 2.2 and newer machine types to avoid
breaking working configs with 2.1 machine type.
