During page table walking, ensure the range being processed matches the expected size of a leaf entry (P4D, PUD, or PMD). While pxd_addr_end() functions handle boundary checks, they do not inherently validate whether the entry is a leaf node of the expected size. Add WARN_ON_ONCE() to detect misalignments or partial updates of huge pages. If a mismatch is detected, return -EINVAL to prevent potential corruption of page table entries.
