Linus Torvalds 29b88e23a9 Driver core patches for 3.17-rc1
Here's the big driver-core pull request for 3.17-rc1.
 
 Largest thing in here is the dma-buf rework and fence code, that touched
 many different subsystems so it was agreed it should go through this
 tree to handle merge issues.  There's also some firmware loading
 updates, as well as tests added, and a few other tiny changes, the
 changelog has the details.
 
 All have been in linux-next for a long time.

Linux Kernel Selftests

The kernel contains a set of "self tests" under the tools/testing/selftests/
directory. These are intended to be small unit tests to exercise individual
code paths in the kernel.

On some systems, hot-plug tests could hang forever waiting for cpu and
memory to be ready to be offlined. A special hot-plug target is created
to run full range of hot-plug tests. In default mode, hot-plug tests run
in safe mode with a limited scope. In limited mode, cpu-hotplug test is
run on a single cpu as opposed to all hotplug capable cpus, and memory
hotplug test is run on 2% of hotplug capable memory instead of 10%.

Running the selftests (hotplug tests are run in limited mode)
=============================================================

To build the tests:

  $ make -C tools/testing/selftests


To run the tests:

  $ make -C tools/testing/selftests run_tests

- note that some tests will require root privileges.

To run only tests targeted for a single subsystem: (including
hotplug targets in limited mode)

  $  make -C tools/testing/selftests TARGETS=cpu-hotplug run_tests

See the top-level tools/testing/selftests/Makefile for the list of all possible
targets.

Running the full range hotplug selftests
========================================

To build the tests:

  $ make -C tools/testing/selftests hotplug

To run the tests:

  $ make -C tools/testing/selftests run_hotplug

- note that some tests will require root privileges.

Contributing new tests
======================

In general, the rules for for selftests are

 * Do as much as you can if you're not root;

 * Don't take too long;

 * Don't break the build on any architecture, and

 * Don't cause the top-level "make run_tests" to fail if your feature is
   unconfigured.
