This patchset is based on tag v5.12-rc3-mmots-2021-03-17-22-26.  To run the
selftest, need to apply the two patches to fix minor mode page leak:

Since I didn't get any NACK in the previous RFC series for months, I decided to
remove the RFC tag starting from this version, so this is v1 of uffd-wp support
on shmem & hugetlb.

Attaching changelog, rfc->v1:
- fix up syzbot reported issue
- add a new feature bit UFFD_FEATURE_WP_SHMEM_HUGETLBFS exported in uapi, so
  that apps can detect the new kernel capability.
- check for all pte_to_swp_entry callers too (hmm, etc.) [JasonG]
- dropped the first few patches that are not directly related to this series; I
  will post them separately as standalone series

Add Cc too (I'll remember to send the series with full cc list next time..).

Thanks,
