This is great work, thanks for putting it together, Benjamin.
Slide 3 of the CMA deck is a bit misleading when it starts by saying
"grabs memory on system boot", but it's otherwise a good summary.
Does it make sense to cover what happens when unmoveable pages are
requested but there isn't enough memory available to allocate outside of
the CMA area?
The DMA buffer slides still need some work to put them in context, as
it starts too low-level to help the reader get the big picture -- i.e.
what problem are we trying to solve? But I trust you're planning on
fleshing that out as you work on the slides.
Can this be a lead-in to actually setting up an area in the wiki which
organizes the current status on the various MM-related threads underway?
I feel that now that we are putting together integration trees and
documentation it would be a good time to invest in making them easy to
