Hi all,
Powerpc systems with a 64K base page size exposed several issues while
running mm selftests. Some tests assume specific hugetlb configurations,
use incorrect interfaces, or fail instead of skipping when the required
kernel features are not available.
This series fixes these issues and improves test robustness.
Please review the patches and provide any feedback or suggestions for
improvement.
Thanks,
Sayali
