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.

Hi,

thank you for all the comments. This patch improve context switch time (by a few ns). FPH is always enabled in Xen.

Tristan.
