RE: [Xen-ia64-devel][Patch]Add two PAL calls which fix SMPwindowsinstallation crashing bug

["Zhang, Xing Z" <xing.z.zhang@xxxxxxxxx>]

In theory, our GFW should do that. I ever tried to just inject GP fault which 
caused by writing PTA to zero to guest and hope windows or GFW can handle the 
fault. However, the result is the VHPT miss fault raise again and again. 
So I think there may be something lost in our GFW, I will investigate into it.

BTW: I can boot windows server 2003 enterprise edition SP1 with more than 8 
vcpus. And all vcpus are available in windows's task manager.  


Good good study,day day up ! ^_^
