acpi_idle and max_cpus

[Daniel Lezcano <daniel.lezcano@xxxxxxxxxx>]

Hi all,

I have a dual core Intel T9500.

I boot the cpu with the acpi_idle driver and intel_idle enabled in the
config.

The kernel is booted with maxcpus=1.

After the system has boot, I put cpu1 online via sysfs.

But I don't see any 'cpuidle' directory in the cpu's sysfs entry:

/sys/devices/system/cpu/cpu1/cpuidle (?)

When I look at the code I see the notifier is present for hotplug in
processor_driver.c and the cpuidle intel init routine should be called
there.

I am wondering is it a bug or an expected behavior ?

Thanks
  -- Daniel
