Binutils 2.38 complains about the use of mfpmr when building
ppc6xx_defconfig:
CC arch/powerpc/kernel/pmc.o
{standard input}: Assembler messages:
{standard input}:45: Error: unrecognized opcode: `mfpmr'
{standard input}:56: Error: unrecognized opcode: `mtpmr'
This is because by default the kernel is built with -mcpu=powerpc, and
the mt/mfpmr instructions are not defined.
It can be avoided by enabling CONFIG_E300C3_CPU, but just adding that to
the defconfig will leave open the possibility of randconfig failures.
So add machine directives around the mt/mfpmr instructions to tell
binutils how to assemble them.

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.
