When KASAN is active, the string functions in lib/ are doing the KASAN checks. This is too early for prom_init. This patch implements dedicated string functions for prom_init, which will be compiled in with KASAN disabled. Size of prom_init before the patch: text data bss dec hex filename 12060 488 6960 19508 4c34 arch/powerpc/kernel/prom_init.o Size of prom_init after the patch: text data bss dec hex filename 12460 488 6960 19908 4dc4 arch/powerpc/kernel/prom_init.o This increases the size of prom_init a bit, but as prom_init is in __init section, it is freed after boot anyway.

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.
