We should start supporting these in Fedora.  These are not unusual to find in

Josh, the reality is that 64 isn't "enough" anymore.  Even deskside systems are
starting to ship with 32 cores, so increasing the number of CPUs to 128 is a
good idea.  I've had a lot of experience with larger systems.  The increase in
memory footprint is minimal (a few Kb, not Mb).

I do know that some vendors who do upstream development, do install Fedora on
systems with greater than 64 logical cpus.  It would be good if we could support
them fully.

Jumping to 128 is a very good idea.  We know it is stable given RHEL's support
of 4096 (again, I don't think Fedora should entertain jumping to 4096 for a
variety of reasons).

In short, ACK ;)
