This patch modifies the initial page mapping functions in the following way: During bootup the init, text and data pages will be mapped RWX and if supported, with huge pages. At final stage of the bootup, the kernel calls free_initmem() and then all pages will be remapped either R-X (for text and read-only data) or RW- (for data). The __init pages will be dropped. This reflects the behaviour of the x86 platform. Signed-off-by: Helge Deller <deller@gmx.de>
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.
