The futextest testsuite [1] provides functional, stress, and
performance tests for the various futex op codes. Those tests will be of
more use to futex developers if they are included with the kernel
source.
Copy the core infrastructure and the functional tests into selftests,
but adapt them for inclusion in the kernel:
- Update the Makefile to include the run_tests target, remove reference
to the performance and stress tests from the contributed sources.
- Replace my dead IBM email address with my current Intel email address.
- Remove the warrantee and write-to paragraphs from the license blurbs.
- Remove the NAME section as the filename is easily determined. ;-)
- Make the whitespace usage consistent in a couple of places.
- Cleanup various CodingStyle violations.
A future effort will explore moving the performance and stress tests
into the kernel.

It was reported that the alarmtimer-suspend test hangs on older
systems that don't support _ALARM clockids.
This is due to the fact that we don't check if the timer_create
fails, and thus when we suspend, the system will not programatically
resume.
Fix this by checking the timer_create call for errors.

When testing on some hardware, waiting only a second before
re-triggering suspend can keep TCP connections from re-establishing
which after a number of cycles can cause TCP connections to close

So extend the delay between suspend calls to 3 seconds to let

Commit commit 5bbe3547aa ("mm: allow compaction of unevictable pages")
introduced a sysctl that allows userspace to enable scanning of locked
pages for compaction. This patch introduces a new test which fragments
main memory and attempts to allocate a number of huge pages to exercise
this compaction logic.
Tested on machines with up to 32 GB RAM. With the patch a much larger
number of huge pages can be allocated than on the kernel without the
patch.
Example output:
On a machine with 16 GB RAM:
sudo make run_tests vm
...
-----------------------
running compaction_test
-----------------------
No of huge pages allocated = 3834

We allocate pcie_link_state for the component at the upstream end of a
Link. Previously we did this by allocating pcie_link_state for Root Ports
and Downstream Ports. This works fine for the typical topology:
00:1c.0 Root Port [bridge to bus 02]
02:00.0 Upstream Port [bridge to bus 03]
03:00.0 Downstream Port [bridge to bus 04]
04:00.0 Endpoint or Switch Port
However, it is possible to have a Root Port connected to a Downstream Port
instead of an Upstream Port, as in Robert White's ATCA system:
00:1c.0 Root Port [bridge to bus 02]
02:00.0 Downstream Port [bridge to bus 03]
03:01.0 Downstream Port [bridge to bus 04]
04:00.0 Endpoint or Switch Port
In this topology, we wrongly allocated pcie_link_state for the 02:00.0
Downstream Port, which is actually the *downstream* end of a link. This
led to the following NULL pointer dereference when we tried to connect this
link into the tree of links starting at the 00:1c.0 Root Port:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000088
IP: [<ffffffff81550324>] pcie_aspm_init_link_state+0x744/0x850
Hardware name: Kontron B3001/B3001, BIOS 4.6.3 08/07/2012
Call Trace:
[<ffffffff8153b865>] pci_scan_slot+0xd5/0x120
[<ffffffff8153ca1d>] pci_scan_child_bus+0x2d/0xd0
...
Instead of relying on the component type to identify the upstream end of a
link, use the "dev->has_secondary_link" field.
This means it's now possible for an Upstream Port to have a link on its
secondary side, so alloc_pcie_link_state() needs to connect links
originating from both Upstream and Downstream Ports into the tree.

drm/i915: Deminish contribution of wait-boosting from clients
we removed an atomic timer based check for allowing waitboosting and
moved it below the mutex taken during RPS. However, that mutex can be
held for long periods of time on Vallyview/Cherryview as communication
with the PCU is slow. As clients may frequently wait for results (e.g.
such as tranform feedback) we introduced contention between the client
and the RPS worker. We can take advantage of the RPS worker, by
switching the wait boost decision to use spin locks and defer the
actual reclocking to the worker.
Fixes a regression of up to 45% on Baytrail and Baswell!
v2 (Daniel):
- Use max_freq_softlimit instead of the not-yet-merged boost
frequency.
- Don't inject a fake irq into the boost work, instead treat
client_boost as just another legit waker.

The srm console is always built in. It will never be modular,
so using module_init as an alias for __initcall is rather
misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero. Should someone with real hardware
for boot testing want to change it later to arch_initcall or
console_initcall, they can do that at a later date.

commit b112889c5a ("iwlwifi: mvm: add Aux ROC request/response flow")
added aux ROC flow in addition to the existing ROC flow. While doing
it, it moved the ROC reference release to a common work item, which
is being called for both the ROC and aux ROC flows.
This resulted in invalid reference accounting, as no reference was
taken in case of aux ROC, while a reference was released on completion.
Fix it by adding a reference for the aux ROC as well, and release
only the relevant references on completion (according to the set bits).
While at it, convert cancel_work_sync() to flush_work(), in order
to make sure the references are being cleaned properly.
