Re: Patch v5 Merge Pkgtemp with coretemp

Hi Guenter,

Thanks for the comments.
Shall fix them and resubmit the patch.
But, I need clarifications on few things here.

I knew it..but I was thinking to do it as a separate patch,
Once this gets acked. If we have to add this support, the following is
my way of doing it:
When a cpu with a core_id is offlined,
check whether there is any other cpu with same core_id(by looping
through for_each_online_cpu()). If so, get that online.
Please let me know if there are any alternatives.

Should that be a separate patch or part of this patch ?

Yes. I already submitted a patch for this. Since we wanted any new patch
On coretemp should be done only after merging pkgtemp, I withheld that patch.

Our probe function itself is called by coretemp_device_add()
which in turn is called by get_core_online(). So, If I move this code
to probe, not sure how the probe itself will be called. Hence, I feel
this code should be here only. Let me know your thoughts.

Thanks,
Durga
