For cxl/ocxl, I have no objection to moving to this new subtree if 
that's what we all agree to do. (what do people do about UAPI headers in 
this situation? keep them where they are in misc/?)

If we do go ahead and set up this new subtree, perhaps we can use the 
mailing list I set up at linux-accelerators at lists.ozlabs.org but we 
haven't really started using...
