Is removing ia64 a serious plan?  It is the cause for a fair share of
oddities in dma lang, and I did not have much luck getting maintainer
replies lately, but I didn't know of a plan to get rid of it.

What is the state of people still using ia64 mainline kernels vs just
old distros in the still existing machines?
