Why not let the arch
arch decide the SUBSECTION_SHIFT and default to one subsection per

Because that keeps the implementation from ever reaching a point where
a namespace might be able to be moved from one arch to another. If we
can squash these arch differences then we can have a common tool to
initialize namespaces outside of the kernel. The one wrinkle is
device-dax that wants to enforce the mapping size,
The fsdax have a much bigger issue right? The file system block size is
the same as PAGE_SIZE and we can't make it portable across archs that
support different PAGE_SIZE?
