Sorry, RFC v2 I think. It got a bit confusing with series names/versions.

Well, my worry is that 2M can be a high tax for smaller machines.
Compile-time might be cleaner, but it has downsides.

It is also not clear if these users actually need physical HZP or virtual
is enough. Virtual is cheap.

We do need physical as the main usecase was for block IO where we will
be DMAing. The main reason I was seeing an improvement in perf was we
were sending bigger chunks of memory in a single bio_vec instead of
using multiple bio_vec.
