Can we please get those two VIA patches merged for 4.10? They are blocking
the final removal of the CPU hotplug notifier crap.
The first one which removes that loop is really harmless as there are no
multisocket VIAs. Heterogenous cores in a single die would be surprising
and the loop check would be the least of our worries in that case. IOW, it
would never get so far...
The one converting the notifier is not changing any of the functionality.
I cannot test on all VIA SMP variants either, but at least on the one I
have access to it just works.
Thanks,
tglx
