Commit 4dfd4bba8578 ("selftests/mm/uffd: refactor non-composite global
vars into struct") moved some of the operations previously implemented
in uffd_setup_environment() earlier in the main test loop.
The calculation of nr_pages, which involves a division by page_size, now
occurs before checking that default_huge_page_size() returns a non-zero
This leads to a division-by-zero error on systems with !CONFIG_HUGETLB.
Fix this by relocating the non-zero page_size check before the nr_pages
calculation, as it was originally implemented.

Do we CC stable on unit tests? From my recollection, no.

Oops, I keep getting confused about this Cc stable thing. Please let me
know if a v2 dropping the tag is needed.

I actually add cc:stable tags to selftests fixes!
Because why not. Why leave people running known-to-be-buggy code when
our backporting processes are so well-functioning and lightweight?
I'm not getting the objection?

I thought we were so inconsistent on that that it ends up being a wasted
effort to even try taking care about stability of selfests in stable trees.

Oh, I try to be vigilant about it.

I pass selftests patches through the same brain algorithm as
I do everything else, shrug.

Thanks for the fix! I never tested with CONFIG_HUGETLB turned off. We
now need tests for tests :)
