JC: can you explicitly confirm that you're ok with letting Tomasz drive
this? We would like to see one driver. Either that is Tomasz, or
Lorenzo, or it is you. But we need to have one overall cooordinated
effort to get this enablement into upstream as quickly as possible.

Some of the Enterprise folks are going to otherwise end up in a very
nasty situation of supporting the previous non-upstream patches for many
years, which is absolutely something we want to avoid...
