Had i ever noticed this hack in the first place i would have NAK-ed it. There is a fundamental design friction of a high-level feature like HOTPLUG_CPU /requiring/ a fundamental change to the lowlevel IRQ delivery mode! Such a requirement is broken and just serves to hide a flaw in the hotplug design - which flaw would trigger on i386 /anyway/, because i386 still uses logical delivery mode for APIC IPIs. Also, i'd like to have a description of how to reproduce those CPU hotplug problems, so that i can try to fix it.
