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.

As crng_initialize_secondary() is only called by do_numa_crng_init(), and the latter is under ifdeffery for CONFIG_NUMA, when CONFIG_NUMA is not selected the compiler will warn that the former is unused: | drivers/char/random.c:820:13: warning: 'crng_initialize_secondary' defined but not used [-Wunused-function] | 820 | static void crng_initialize_secondary(struct crng_state *crng) | | ^~~~~~~~~~~~~~~~~~~~~~~~~ Stephen reports that this happens for x86_64 noallconfig builds. We could move crng_initialize_secondary() and crng_init_try_arch() under the CONFIG_NUMA ifdeffery, but this has the unfortunate property of separating them from crng_initialize_primary() and crng_init_try_arch_early() respectively. Instead, let's mark crng_initialize_secondary() as __maybe_unused.
