This uses struct pgtable_debug_args in PTE modifying tests. The allocated page is used as set_pte_at() is used there. The tests are skipped if the allocated page doesn't exist. It's notable that args->ptep need to be mapped before the tests. The reason why we don't map args->ptep at the beginning is PTE entry is only mapped and accessible in atomic context when CONFIG_HIGHPTE is enabled. So we avoid to do that so that atomic context is only enabled if needed. Besides, the unused variable @pte_aligned and @ptep in debug_vm_pgtable() are dropped.

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.
