It looks like CONFIG_BOOTPARAM_HOTPLUG_CPU0=3Dy is the reason for the warni= ng. As J=C3=BCrgen suggested in another mail, Xen should probably disable hotpl= ugging for cpu#0 in the generic setup code. Then cpu_is_hotpluggable(cpu) would do the right thing. Do you want me to merge that extra change into this patch?
