[Xen-devel] [PATCH] Dom0: Fix bad pte at booting time

["Xu, Dongxiao" <dongxiao.xu@xxxxxxxxx>]

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@xxxxxxx>, with commit: 70c9f590ffc3f959cc81c1a3cecb6b8133caf35d
