Explicit review requests, but any other feedback is of course
appreciated:

Patch1 needs an ack from ppc arch maintainers, and I'd like a tested-by
from Aneesh that this still works to solve the ppc issue. Jeff, does
this look good to you?

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!
