Hi, Thomas,
What do you think about this patch? Other archs also do the same thing
except those support hotplug CPU#0.
I'm ok with the patch, I'm just wondering if this is a hardware or
software limitation. If it's the latter, what needs to be done to
support it ?
It should be a software limitation, x86 have already deal with that [1].
But there is no reason to spend extra effort on CPU0 hotplug. I don't
think any user is expecting this feature.
Thanks.
