As I found out recently, memory hotplug is disabled in f17 and f18
kernels (but not in f16).
Can anybody please recall the reason for that?
The commit doing that is not particularly enlightening:

Disable memory hotplug on x86-64
I'd like to propose to re-enable it but I'm trying to figure out why
it was disabled in the first place.
Thanks,
Roman.
