Hi Tristan,
    I don't think this patch is needed for VTi domain. Oppositely, it may cause errors for stacked converntion calls. Because I recalled that stacked convention calls' parameters  have been transferred into static ones before trapping into VMM in vPAL.  I will check the code here and to see whether stack registers are tainted before the trap. 
Thanks,
Xiantao

Hi,

[I thought I have already sent this patch but I can't see it in the ml
archive].

This patch implements stacked PAL call in VTi.

Tristan.
