Thanks. Julien/Stefano: Why are any of these hypercalls out-of-line? ARM doesn't use the hypercall page, and there is no argument translation (not even in arm32 as there are no 5-argument hypercalls declared). They'd surely be easier to implement with a few static inlines and some common code, than to try and replicate the x86 side hypercall_page interface ? ~Andrew
