Thomas Gleixner fc8dffd379 cpu/hotplug: Convert hotplug locking to percpu rwsem
There are no more (known) nested calls to get_online_cpus() and all
observed lock ordering problems have been addressed.

Replace the magic nested 'rwsem' hackery with a percpu-rwsem.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
