Backport upstream kernel patch to fix Dom0's bad pte bug.
- In Dom0 kernel, at boot time, system will call bt_ioremap() to do mappings for the Boot Time Fix Memory region. Also system will call bt_iounmap() to unmap the memory region by setting phys=0. In this case, system will encounter pte_ERROR(). This patch backports the upstream kernel patch by Ingo Molnar <mingo@elte.hu>, with commit: 70c9f590ffc3f959cc81c1a3cecb6b8133caf35d
