Push the VMA_LOCK check down from __handle_mm_fault() to handle_pte_fault(). Once again, we refuse to call ->huge_fault() with the VMA lock held, but we will wait for a PMD migration entry with the VMA lock held, handle NUMA migration and set the accessed bit. We were already doing this for anonymous VMAs, so it should be safe.

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 Restructured Text 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.
