Modified Files:
        src/sys/arch/xen/x86: xen_bus_dma.c

Log Message:
Properly honnor bus_dma bus address range restriction for Xen3 (the Xen2
interface doesn't allow it), so that .e.g bus_dma_subregion() has a chance
to work. Unfortunably a stock Xen hypervisor won't allow a upper bound less
than 2^31 (2GB) so devices like bce(4) will need a hacked hypervisor to
work properly.
