Change HUGEPAGE_SIZE to become 4 MB on 32-bit kernels, which leads that kernel code and kernel data will start on 4 MB boundaries. Although a 32-bit kernel does not support huge pages, most machines have support for Block-TLBs (BTLB) which allow to configure the system to use large pages (block TLBs) to minimize the TLB contention. This is done through calls to PDC and the 32-bit kernel can then call BTLB PDC functions to tell the machine to optimize the TLBs. 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.
