q35: gigabyte alignment for ram
Map 2G (q35) of memory below 4G, so the RAM pieces are nicely aligned to gigabyte borders. Keep old memory layout for (a) old machine types and (b) in case all memory fits below 4G and thus we don't have to split RAM into pieces in the first place. The later makes sure this change doesn't take away memory from 32bit guests. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>
