Hi all,
This patch series addresses false positives in the generic mm selftests and skips tests that cannot run correctly due to missing features or system limitations.
---
v1: https://lore.kernel.org/all/20250616160632.35250-1-aboorvad@linux.ibm.com/
Changes in v2:
- Rebased onto the mm-new branch, top commit of the base is 3b4a8ad89f7e ("mm: add zblock allocator"). - Split some patches for clarity. - Updated virtual_address_range test to support testing 4PB VA on PPC64. - Added proper Fixes: tags. - Included a patch to skip a failing userfaultfd test when unsupported, instead of reporting a failure.

Please let us know if you have any further comments.
Thanks, Aboorva
