OK, I've reviewed everything.  Testing looks good with the change I
mentioned (memremap_compat_align returning PAGE_SIZE).  I made sure a
4k-aligned namespace created under an unpatched kernel would be
accessible under a patched kernel.  I also made sure that manually
setting align would allow for creating of poorly aligned namespaces, and
that those namespaces were then accessible on the unpatched kernel.

Thanks, Dan!
