Patch series "mm: page_table_check: add support on arm64 and riscv", v7. Page table check performs extra verifications at the time when new pages become accessible from the userspace by getting their page table entries (PTEs PMDs etc.) added into the table. It is supported on X86[1]. This patchset made some simple changes and make it easier to support new architecture, then we support this feature on ARM64 and RISCV. [1]https://lore.kernel.org/lkml/20211123214814.3756047-1-pasha.tatashin@soleen.com/ This patch (of 6): Compared with PxD_PAGE_SIZE, which is defined and used only on X86, PxD_SIZE is more common in each architecture. Therefore, it is more reasonable to use PxD_SIZE instead of PxD_PAGE_SIZE in page_table_check.c. At the same time, it is easier to support page table check in other architectures. The substitution has no functional impact on the x86.

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.
