Patch series "mm: mincore: misc cleanups", v3. This series cleans up and simplifies the mincore. Most importantly, it removes the historical special behavior that always reports VM_PFNMAP pages as non-resident. This patch (of 6): Introduce the pud_is_huge() helper function to check whether a PUD is a huge PUD or a software leaf entry. Note that, unlike PMD, PUD currently does not support transparent migration entries or device private entries. However, the function still includes `!pud_none()` branches to accommodate potential future implementations.
