Modified Files:
        src/sys/arch/xen/xen: privcmd.c

Log Message:
IOCTL_PRIVCMD_MMAPBATCH used guest physical address 0x0 to mark a page as 
invalid.
Since we have to treat 0x0 as a valid page, this got broken in rev. 1.26.
Introduce INVALID_PAGE as magic value and restore the check.
This unbreaks IOCTL_PRIVCMD_MMAPBATCH while allowing to launch HVM guests.
