Move a few kfence and debug_pagealloc related functions in hash_utils.c and radix_pgtable.c to __init sections since these are only invoked once by an __init function during system initialization. i.e. - hash_debug_pagealloc_alloc_slots() - hash_kfence_alloc_pool() - hash_kfence_map_pool() The above 3 functions only gets called by __init htab_initialize(). - alloc_kfence_pool() - map_kfence_pool() The above 2 functions only gets called by __init radix_init_pgtable() This should also help fix warning msgs like: >> WARNING: modpost: vmlinux: section mismatch in reference: hash_debug_pagealloc_alloc_slots+0xb0 (section: .text) -> memblock_alloc_try_nid (section: .init.text) Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202504190552.mnFGs5sj-lkp@intel.com/ Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> Link: https://lore.kernel.org/r/20250717232519.2984886-8-kees@kernel.org Signed-off-by: Kees Cook <kees@kernel.org>
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.
