Set Xen kernel virtual address to 0xC0000000
That makes the virtual addressing equal to linear addressing, thus optimizing
some computations away.
* i386/i386/vm_param.h (VM_MIN_KERNEL_ADDRESS) [MACH_XEN]: Set to
0xC0000000UL.
* i386/xen/Makefrag.am (gnumach_LINKFLAGS): Set _START to 0xC0000000.
* i386/xen/xen_boothdr.S (VIRT_BASE, ELF_PADDR_OFFSET): Set to 0xC0000000.
