On a slightly different topic, how come we're using physflat for hotplug
cpu?
-#ifndef CONFIG_CPU_HOTPLUG
/* In the CPU hotplug case we cannot use broadcast mode
because that opens a race when a CPU is removed.
- Stay at physflat mode in this case.
- It is bad to do this unconditionally though. Once
- we have ACPI platform support for CPU hotplug
- we should detect hotplug capablity from ACPI tables and
- only do this when really needed. -AK */
+ Stay at physflat mode in this case. - AK */
+#ifdef CONFIG_HOTPLUG_CPU
if (num_cpus <= 8)
genapic = &apic_flat;
