Initialize PV spinlocks on boot CPU right after native_smp_prepare_cpus (that switch to APIC mode and initialize APIC routing); on secondary CPUs on CPU_UP_PREPARE. Enable the usage of event channels to send and receive IPIs when running as a PV on HVM guest. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
