When an ifdef is used in the below manner, second one could be considered as duplicate. ifdef DEFINE_A ...code block... ifdef DEFINE_A <-- This is a duplicate. ...code block... endif else ifndef DEFINE_A <-- This is also duplicate. ...code block... endif endif More details about the script and methods used to find these code patterns are in cover letter of [1]. Few places in arch/powerpc where this pattern was seen: paca.h: Hunk1: Code is under check of CONFIG_PPC64 from line 13, hence the second CONFIG_PPC64 at line 166 is a duplicate. Hunk2: CONFIG_PPC_BOOK3S_64 was defined back to back. Merged the two ifdefs. asm-offsets.c: Code is under check of CONFIG_PPC64 from line 176 hence second CONFIG_PPC64 at line 249 is a duplicate. powermac/feature.c: #ifndef CONFIG_PPC64 is used at line 2066. And then in #else again #ifdef CONFIG_PPC64 is used. Which is a duplicate since in #else means CONFIG_PPC64 is defined. xmon.c: Code is under the check of CONFIG_SMP from line 521 hence the same check of CONFIG_SMP at line 646 is a duplicate. No functional change is intended here. It only aims to improve code readability.

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.
