Add device-private THP support to reverse mapping infrastructure, enabling proper handling during migration and walk operations. The key changes are: - add_migration_pmd()/remove_migration_pmd(): Handle device-private entries during folio migration and splitting - page_vma_mapped_walk(): Recognize device-private THP entries during VMA traversal operations This change supports folio splitting and migration operations on device-private entries.

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.
