Message-ID: <1367436460-10183-3-git-send-email-stefano.stabellini@eu.citrix.com> (raw)
In-Reply-To: <alpine.DEB.2.02.1305011939180.5398@kaball.uk.xensource.com>

Register the runstate_memory_area with the hypervisor.
Use arch_timer_stolen_ticks and xen_stolen_accounting to account for
stolen ticks.
