It is queued for 4.5 currently.

Xen 32-bit PV guests are broken without this.
So this needs to go into 4.4 or even earlier? Since 5f310f739b4c went
into 4.4, I'd think 4.4 only for this fix too? Yes?

Oh, I didn't realize this is scheduled for 4.5. It indeed needs to go into 4.4 because of 5f310f739b4c.

Thanks.
