Our logic for choosing defconfig doesn't work well in some situations. For example if you're on a ppc64le machine but you specify a non-empty CROSS_COMPILE, in order to use a non-default toolchain, then defconfig will give you ppc64_defconfig (big endian): $ make CROSS_COMPILE=~/toolchains/gcc-8/bin/powerpc-linux- defconfig *** Default configuration is based on 'ppc64_defconfig' This is because we assume that CROSS_COMPILE being set means we can't be on a ppc machine and rather than checking we just default to ppc64_defconfig. We should just ignore CROSS_COMPILE, instead check the machine with uname and if it's one of ppc, ppc64 or ppc64le then use that defconfig. If it's none of those then we fall back to ppc64_defconfig.

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.
