Geert Uytterhoeven 62f55ce683 ARM: shmobile: r8a7779: Stop powering down secondary CPUs during early boot
At .smp_prepare_cpus() time, CPUs 1-3 are still powered down:
  - The bootloader doesn't enable CPUs 1-3,
  - Non-boot CPUs are disabled by kexec before starting the new kernel.

Hence there is no need to try to power them down again, as it will fail
silently with -EIO 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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
