What are the plan for maintenance in near future in case kernel
support never lands?  Would ARM, Cavium, and other interested
parties to keep maintain both kernel and glibc branches indefinitely
in such cases? 

I am asking it because for ABI merge on glibc without the current
requiring bump might be easier to manage if we an outlined plan
(and a fallback one if we continue without kernel support).
