Jess,

So dropping ia64 from the upstream kernel won't just save time of kernel
developers. It will also save time for the folks keeping Debian and Gentoo
ports up and running.

Are there people actually running production systems on ia64 that also
update to v6.x kernels?

If so, why? Just scrap the machine and replace with almost anything else.
You'll cover the cost of the new machine in short order with the savings on
your power bill.
