Remove some stray blank lines, convert a printk to pr_warn, and
address a line length violation.
One functional change: use WARN_ON instead of BUG_ON in case H_PROD of
a ceded thread yields an unexpected result from the platform. We can
expect this code path to get uninterruptibly stuck in __cpu_die() if
this happens, but that's more desirable than crashing.

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.
