The code: ifdef CONFIG_6xx KBUILD_CFLAGS += -mcpu=powerpc endif was added in 2006 in commitf48b8296b3("[PATCH] powerpc32: Set cpu explicitly in kernel compiles"). This change was acceptable since the TARGET_CPU logic was 64-bit only. Since commit0e00a8c9fd("powerpc: Allow CPU selection also on PPC32") this logic is no longer acceptable after the TARGET_CPU specific. It currently appends -mcpu=powerpc at the end of the command line, after any TARGET_CPU specific: gcc -Wp,-MD,init/.do_mounts.o.d ... -mcpu=powerpc -mbig-endian -m32 ... -mcpu=e300c2 ... -mcpu=powerpc ... ../init/do_mounts.c Fixes:0e00a8c9fd("powerpc: Allow CPU selection also on PPC32") Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
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.
