mm: introduce pud_is_huge() helper
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.
