I will post a patch shortly with the cpu bitmask change. Changing
__cpu_notify() will take more discussion.

Yes. We have a system in the lab with 254 12-core IVB sockets for
a total of 3048 cores. With HT is it 6096 cpus.

If not, scan the list as before.
A 4 TB (single rack) UV1 system takes 512 seconds to get through
