Alex,

please do not integrate xen-system4.diffs.

After much testing, there is at least one path where saving fp registers 
faults (I got it with a 12 VCPUs domain).  I have to look more.

Please, integrate xen-system3.diffs (the previous one), it is much more safer.

Excuse me for not testing enough.  I am sorry.

Tristan.
