Setting pv_irq_ops for Xen PV domains should be done as early as possible in order to support e.g. very early printk() usage.
Will printk() work as result of this move? We still, for example, haven't set up console.
It will print to the kernel print buffer, so the output will be available later.
Right, haven't thought about it.
This will (probably) allow us not to crash (due to STI and such) but I am not sure "support" is the right term here.
Not crashing is big plus IMO. :-)
Actually, no, this is not sufficient.
You need to move xen_vcpu_info_reset(0) up as well. Otherwise you will not be able to dereference the percpu xen_vcpu in xen_save_fl().
