It'll also conditionally generate the defines, so that if we don't have
those when building a new tool tarball in an older systems, we get
those, and we need them sometimes in the actual scnprintf routine, such
as when checking if a flags means we have an extra arg, like with
MREMAP_FIXED.
$ tools/perf/trace/beauty/mremap_flags.sh
static const char *mremap_flags[] = {
[ilog2(1) + 1] = "MAYMOVE",
#ifndef MREMAP_MAYMOVE
#define MREMAP_MAYMOVE 1
#endif
[ilog2(2) + 1] = "FIXED",
#ifndef MREMAP_FIXED
#define MREMAP_FIXED 2
#endif
[ilog2(4) + 1] = "DONTUNMAP",
#ifndef MREMAP_DONTUNMAP
#define MREMAP_DONTUNMAP 4
#endif
};

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.
