Thread-topic: [PATCH] avoid gp fault vmexits

Hi Keir, Ian,

    The current Xen code for VMX is setting the gp fault vmexiting in the EXCEPTION_BITMAP vmcs control. There is no need for that as VMM is just plainly re-injecting back to the guest. The attached is a simple patch to set the vmcs control properly.

Thanks & Regards,

Nitin
