Thread-topic: [PATCH][IA64] Fix Qemu memory access beyond 3G
This patch intends to fix memory access beyond 3G for VTi domain.
Currently VTi's memory beyond 3G was moved to 4G at build time. So it
should be mapped correctly in qemu. If not, it will cause qemu's
segmentation fault when guest use memory beyond 4G for DMA.
