My GTX660 has the GPIO_FAN function, but it's configured in input-mode;
presumably to monitor the frequency set by an I2C fan controller?

For now, we only boost the fan speed to the maximum and auto-mode
when hitting the FAN_BOOST threshold and halt the computer when it
reaches the shutdown temperature. The downclock and critical thresholds
do nothing.
On nv43:50 and nva3+, temperature is polled because of the limited hardware.
I'll improve the nva3+ situation by implementing alarm management in PDAEMON
whenever I can but polling once every second shouldn't be such a problem.

We are going to use PTHERM's IRQs for thermal monitoring but we need to route
them first.
On nv31-50, PBUS's IRQ line is shared with GPIOs IRQs.
It seems like nv10-31 GPIO interruptions aren't well handled. I kept the
original behaviour but it is wrong and may lead to an IRQ storm.
Since we enable all PBUS IRQs, we need a way to avoid being stormed if we
don't handle them. The solution I used was to mask the IRQs that have not been
handled. This will also print one message in the logs to let us know.
v2: drop the shared intr handler because of was racy
v3: style fixes
v4: drop a useless construct in the chipset-dependent INTR
v5: add BUS to the disable mask
v6 (Ben Skeggs):
- general tidy to match the rest of the driver's style
- nva3->nvc0, nva3 can be serviced just fine with nv50.c, rnndb even notes
that the THERM_ALARM bit got left in the hw until fermi anyway.. so, it's
not going to conflict
- removed the peephole and user stuff, for the moment.. will handle them
later if we find a good reason to actually care..
- limited INTR_EN to just what we can handle for now, mostly to prevent
spam of unknown status bits (seen on at least nv4x)

v2: improved design but drops safety monitoring (to be in a later patch)
v3: fix locking and mode management
v4: gently fallback to the no-control mode when temperature cannot be got

v5 (Ben Skeggs):
- rebased on my previous patches
v6: fix hysterisis management in trip-based auto fan management
This commit also forbids access to fan management to nvc0+ chipsets as
fan management is already taken care of my PDAEMON's default fw.

Pull workqueue [delayed_]work_pending() cleanups from Tejun Heo:
"This is part of on-going cleanups to remove / minimize usages of
workqueue interfaces which are deprecated and/or misleading.
This round drops a number of usages of [delayed_]work_pending(), which
are dangerous as they lack any form of synchronization and thus often
lead to buggy / unnecessary code. There are a couple legitimate use
cases in kernel. Hopefully, they can be converted and
[delayed_]work_pending() can be removed completely. Even if not,
removing most of misuses should make it more difficult to find
examples of misuses and thus slow down growth of them.
These changes are independent from other workqueue changes."

ioremap can't be used to map ring pages on ARM because it uses device
memory caching attributes (MT_DEVICE*).
Introduce a Xen specific abstraction to map ring pages, called
xen_remap, that is defined as ioremap on x86 (no behavioral changes).
On ARM it explicitly calls __arm_ioremap with the right caching
attributes: MT_MEMORY.

This patch implement real Xen ACPI cpu hotplug driver as module.
When loaded, it replaces Xen stub driver.
For booting existed cpus, the driver enumerates them.
For hotadded cpus, which added at runtime and notify OS via

parsing cpu information, hypercalling to Xen hypervisor to add
them, and finally setting up new /sys interface for them.

This patch create a file (xen-stub.c) for Xen stub drivers.
Xen stub drivers are used to reserve space for Xen drivers, i.e.
memory hotplug and cpu hotplug, and to block native drivers loaded,
so that real Xen drivers can be modular and loaded on demand.
This patch is specific for Xen memory hotplug (other Xen logic
can add stub drivers on their own). The xen stub driver will
occupied earlier via subsys_initcall (than native memory hotplug
driver via module_init and so blocking native). Later real Xen
memory hotplug logic will unregister the stub driver and register
itself to take effect on demand.

"There are lots of improvements, the biggest changes are:
Main kernel side changes:
- Improve uprobes performance by adding 'pre-filtering' support, by
Oleg Nesterov.
- Make some POWER7 events available in sysfs, equivalent to what was
done on x86, from Sukadev Bhattiprolu.
- tracing updates by Steve Rostedt - mostly misc fixes and smaller
improvements.
- Use perf/event tracing to report PCI Express advanced errors, by

- Enable northbridge performance counters on AMD family 15h, by Jacob
Shin.
- This tracing commit:
tracing: Remove the extra 4 bytes of padding in events
changes the ABI. All involved parties (PowerTop in particular)
seem to agree that it's safe to do now with the introduction of
libtraceevent, but the devil is in the details ...
Main tooling side changes:
- Add 'event group view', from Namyung Kim:
To use it, 'perf record' should group events when recording. And
then perf report parses the saved group relation from file header
and prints them together if --group option is provided. You can
use the 'perf evlist' command to see event group information:
$ perf record -e '{ref-cycles,cycles}' noploop 1
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ]
$ perf evlist --group
{ref-cycles,cycles}
With this example, default perf report will show you each event
separately.
You can use --group option to enable event group view:
$ perf report --group
...
# group: {ref-cycles,cycles}
# ========
# Samples: 7K of event 'anon group { ref-cycles, cycles }'
# Event count (approx.): 6876107743
#
# Overhead Command Shared Object Symbol
# ................ ....... ................. ..........................
99.84% 99.76% noploop noploop [.] main

As you can see the Overhead column now contains both of ref-cycles
and cycles and header line shows group information also - 'anon
group { ref-cycles, cycles }'. The output is sorted by period of
group leader first.
- Initial GTK+ annotate browser, from Namhyung Kim.
- Add option for runtime switching perf data file in perf report,
just press 's' and a menu with the valid files found in the current
directory will be presented, from Feng Tang.
- Add support to display whole group data for raw columns, from Jiri
Olsa.
- Add per processor socket count aggregation in perf stat, from
Stephane Eranian.
- Add interval printing in 'perf stat', from Stephane Eranian.
- 'perf test' improvements
- Add support for wildcards in tracepoint system name, from Jiri
Olsa.
- Add anonymous huge page recognition, from Joshua Zhu.
- perf build-id cache now can show DSOs present in a perf.data file
that are not in the cache, to integrate with build-id servers being
put in place by organizations such as Fedora.
- perf top now shares more of the evsel config/creation routines with
'record', paving the way for further integration like 'top'
snapshots, etc.
- perf top now supports DWARF callchains.
- Fix mmap limitations on 32-bit, fix from David Miller.
- 'perf bench numa mem' NUMA performance measurement suite
- ... and lots of fixes, performance improvements, cleanups and other

git://people.freedesktop.org/~danvet/drm-intel into drm-next
So here's my promised pile of fixes for 3.9. I've dropped the core prep
patches for vt-switchless suspend/resume as discussed on irc. Highlights:
- Fix dmar on g4x. Not really gfx related, but I'm fed up with getting
blamed for dmar crapouts.
- Disable wc ptes updates on ilk when dmar is enabled (Chris). So again,
dmar, but this time gfx related :(
- Reduced range support for hsw, using the pipe CSC (Ville).
- Fixup pll limits for gen3/4 (Patrick Jakobsson). The sdvo patch is
already confirmed to fix 2 bug reports, so added cc: stable on that one.
- Regression fix for 8bit fb console (Ville).
- Preserve lane reversal bits on DDI/FDI ports (Damien).
- Page flip vs. gpu hang fixes (Ville). Unfortuntely not quite all of
them, need to decide what to do with the currently still in-flight ones.
- Panel fitter regression fix from Mika Kuoppala (was accidentally left on
on some pipes with the new modset code since 3.7). This also improves
the modeset sequence and might help a few other unrelated issues with
lvds.
- Write backlight regs even harder ... another installement in our eternal
fight against the BIOS and backlights.
- Fixup lid notifier vs. suspend/resume races (Zhang Rui). Prep work for
new ACPI stuff, but closing the race itself seems worthwile on its own.
- A few other small fixes and tiny cleanups all over.
Lots of the patches are cc: stable since I've stalled on a few
not-so-important fixes for 3.8 due to the grumpy noise Linus made.

Use the I2C_ADDRS macro to initialize the I2C device's address_list. Doing so
saves a few lines of boilerplate code.
