Patch series "mm: small cleanups for io-mapping, debug_page_alloc and numa". This series includes three small cleanups to mm/: - io-mapping: simplify remap protection flag calculation - debug_page_alloc: improve error message by printing invalid input - numa: remove unnecessary variable for clarity No functional changes. This patch (of 3): In io_mapping_map_user(), precompute the page protection flags in a local variable before calling remap_pfn_range_notrack(). No functional change.

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.
