Extend core huge page management functions to handle device-private THP entries. This enables proper handling of large device-private folios in fundamental MM operations. The following functions have been updated: - copy_huge_pmd(): Handle device-private entries during fork/clone - zap_huge_pmd(): Properly free device-private THP during munmap - change_huge_pmd(): Support protection changes on device-private THP - __pte_offset_map(): Add device-private entry awareness Link: https://lkml.kernel.org/r/20251001065707.920170-4-balbirs@nvidia.com Signed-off-by: Matthew Brost <matthew.brost@intel.com> Signed-off-by: Balbir Singh <balbirs@nvidia.com> Acked-by: Zi Yan <ziy@nvidia.com> Cc: David Hildenbrand <david@redhat.com> Cc: Joshua Hahn <joshua.hahnjy@gmail.com> Cc: Rakie Kim <rakie.kim@sk.com> Cc: Byungchul Park <byungchul@sk.com> Cc: Gregory Price <gourry@gourry.net> Cc: Ying Huang <ying.huang@linux.alibaba.com> Cc: Alistair Popple <apopple@nvidia.com> Cc: Oscar Salvador <osalvador@suse.de> Cc: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> Cc: Baolin Wang <baolin.wang@linux.alibaba.com> Cc: "Liam R.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
