Subject: mm: make zap_pte_range() handle full within-PMD range
Date: Wed, 4 Dec 2024 19:09:48 +0800

In preparation for reclaiming empty PTE pages, this commit first makes zap_pte_range() to handle the full within-PMD range, so that we can more easily detect and free PTE pages in this function in subsequent commits.
