The private data 'pm', 'pt', and 'pp' array members hold the trigger mode
parameters for ports A and B. Both ports are 8-bits and the arrays are 16-bits.
Array index 0 defines the AND mode and index 1 the OR mode parameters for both
ports.

The valid triggers to start the async command are 0 to 3 which select the
AND/OR mode for each port.

The 'pb_trig' (the array index for port B) in apci1500_di_inttrig_start() is
incorrect and results in an index of 0 or 2. Fix the calc so that the correct
index (0/1) is used.

The I2O layer deals with a technology that to say the least didn't catch on
in the market.

The only relevant products are some of the AMI MegaRAID - which supported I2O
and its native mode (The native mode is faster and runs on Linux), an
obscure crypto ethernet card that's now so many years out of date nobody
would use it, the old DPT controllers, which speak their own dialect and
have their own driver - and ermm.. thats about it.

We also know the code isn't in good shape as recently a patch was proposed
and queried as buggy, which in turn showed the existing code was broken
already by prior "clean up" and nobody had noticed that either.

It's coding style robot code nothing more. Like some forgotten corridor
cleaned relentlessly by a lost Roomba but where no user has trodden in years.

Move it to staging and then to /dev/null.

The headers remain as they are shared with dpt_i2o.

  Input: synaptics - adjust min/max for Lenovo ThinkPad X1 Carbon 2nd

Commit 8eb23b9f ("sched: Debug nested sleeps") added code to report
on nested sleep conditions, which we generally want to avoid because the
inner sleeping operation can re-set the thread state to TASK_RUNNING,
but that will then cause the outer sleep loop not actually sleep when it
calls schedule.

However, that's actually valid traditional behavior, with the inner
sleep being some fairly rare case (like taking a sleeping lock that
normally doesn't actually need to sleep).

And the debug code would actually change the state of the task to
TASK_RUNNING internally, which makes that kind of traditional and
working code not work at all, because now the nested sleep doesn't just
sometimes cause the outer one to not block, but will cause it to happen
every time.

In particular, it will cause the cardbus kernel daemon (pccardd) to
basically busy-loop doing scheduling, converting a laptop into a heater,
as reported by Bruno Prémont.  But there may be other legacy uses of
that nested sleep model in other drivers that are also likely to never
get converted to the new model.

This fixes both cases:

 - don't set TASK_RUNNING when the nested condition happens (note: even
   if WARN_ONCE() only _warns_ once, the return value isn't whether the
   warning happened, but whether the condition for the warning was true.
   So despite the warning only happening once, the "if (WARN_ON(..))"
   would trigger for every nested sleep.

 - in the cases where we knowingly disable the warning by using
   "sched_annotate_sleep()", don't change the task state (that is used
   for all core scheduling decisions), instead use '->task_state_change'
   that is used for the debugging decision itself.

(Credit for the second part of the fix goes to Oleg Nesterov: "Can't we
avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the
suggested change to use 'task_state_change' as part of the test)

Jonathan writes:

Second round of IIO new drivers, functionality and cleanups for the 3.20 cycle.

New drivers and device support:
* Capella cm3232 ambient light sensor driver.
* Freescale MMA9553 pedometer and activity monitor. Note this involved a
  refactor of the mma9551 driver to pull out shared elements.
* Samsung sensor hub (as used in the galaxy gear 2 watch) Core support
  and initial drivers (gyro and accelerometer) more to follow.
  An additional fix was applied on top of this for a build issue
  thrown up by the autobuilders on some platforms.
* Cosmic Circuits 10001 ADC driver
* Qualcomm SPMI PMIC voltage ADC driver (current adc merged a while back).
* Add binding for AK8963 (in capitals) as unfortunately there are bios'
  out there not using lower case.

New functionality
* Add newe operating mode to the core to allow for non triggered software
  buffers.  This is mostly semantics as previously drivers just claimed they
  had a hardware buffer (when they didn't).
* Add distance channel type.
* Add energy channel type.
* Add velocity channel type and IIO_MOD_ROOT_SUM_SQUARED (i.e. speed when
  our channel type is velocity).
* Add _debounce_count and _debounce_time filter attributes.  Only really
  make sense for counting types of measurements.  First use is for avoiding
  miss detection of steps prior to walking.
* Add change event type.   This replaces the briefly present INSTANCE type
  (which hadn't gained any users).  It is more generic as it allows for
  events say every 10 steps rather than every step.
* Add _calibweight attributes to the ABI (and core support).  Used by
  activity monitors to estimate energy use.  Can imagine there will be
  other uses for this one.

Driver new functionality
* mma9551 gains runtime pm support.
* hid-sensors gain PM support.

Cleanup
* Change calibheight unit to m from cm.  As there are no prior users
  and this was inconsistent with other distance units, it makes sense
  to fix it before hte mma9553 driver which uses it.
* mpu6050 cleanups and devm_ use.
* as3935 switch over to PM ops.
* Fix a few format strings for signed vs unsigned.
* Fix tcs3414 missindentation
* Typo in industrialio-event
* Stop requiring IIO_TRIGGER for IIO_KFIFO_BUF as we have drivers that don't
  need it. No one is quite sure why that dependency was there and it
  seems to not matter.

Also change to div64_u64 in one place to avoid loss of precision
(was dividing a 32 bit number by a 64 bit number, but casting this
to 64 bit divided by 32 bit)  Those divide functions certainly have
esoteric naming!

Fixes warnings with asm-generic/div64.h do_div such as:
   In file included from drivers/iio/common/ssp_sensors/ssp_iio.c:20:0:
   drivers/iio/common/ssp_sensors/ssp_iio_sensor.h: In function 'ssp_convert_to_freq':

   drivers/iio/common/ssp_sensors/ssp_iio.c:83:10: note: 'calculated_time' was declared here

Fixed by using straight coded version as per the description in the
div64.h header, thus ensuring no issue with 32 bit integers.

When handling a fault in stage-2, we need to resync I$ and D$, just
to be sure we don't leave any old cache line behind.

That's very good, except that we do so using the *user* address.
Under heavy load (swapping like crazy), we may end up in a situation
where the page gets mapped in stage-2 while being unmapped from
userspace by another CPU.

At that point, the DC/IC instructions can generate a fault, which
we handle with kvm->mmu_lock held. The box quickly deadlocks, user
is unhappy.

Instead, perform this invalidation through the kernel mapping,
which is guaranteed to be present. The box is much happier, and so
am I.

Let's assume a guest has created an uncached mapping, and written
to that page. Let's also assume that the host uses a cache-coherent
IO subsystem. Let's finally assume that the host is under memory
pressure and starts to swap things out.

Before this "uncached" page is evicted, we need to make sure
we invalidate potential speculated, clean cache lines that are
sitting there, or the IO subsystem is going to swap out the
cached view, loosing the data that has been written directly

Trying to emulate the behaviour of set/way cache ops is fairly
pointless, as there are too many ways we can end-up missing stuff.
Also, there is some system caches out there that simply ignore
set/way operations.

So instead of trying to implement them, let's convert it to VA ops,
and use them as a way to re-enable the trapping of VM ops. That way,
we can detect the point when the MMU/caches are turned off, and do
a full VM flush (which is what the guest was trying to do anyway).

This allows a 32bit zImage to boot on the APM thingy, and will
probably help bootloaders in general.

arm_iommu_attach_device() to arch_setup_dma_ops() where the DMA
operations to be used are selected based on whether the device is
connected to an IOMMU. However, the IOMMU detection scheme requires the
IOMMU driver to be ported to the new IOMMU of_xlate API. As no driver
has been ported yet, this effectively breaks all IOMMU ARM users that
depend on the IOMMU being handled transparently by the DMA mapping API.

Fix this by restoring the setting of DMA IOMMU ops in
arm_iommu_attach_device() and splitting the rest of the function into a
new internal __arm_iommu_attach_device() function, called by
arch_setup_dma_ops().

The core VM already knows about VM_FAULT_SIGBUS, but cannot return a
"you should SIGSEGV" error, because the SIGSEGV case was generally
handled by the caller - usually the architecture fault handler.

That results in lots of duplication - all the architecture fault
handlers end up doing very similar "look up vma, check permissions, do
retries etc" - but it generally works.  However, there are cases where
the VM actually wants to SIGSEGV, and applications _expect_ SIGSEGV.

In particular, when accessing the stack guard page, libsigsegv expects a
SIGSEGV.  And it usually got one, because the stack growth is handled by
that duplicated architecture fault handler.

However, when the generic VM layer started propagating the error return
from the stack expansion in commit fee7e49d ("mm: propagate error
from stack expansion even for guard page"), that now exposed the
existing VM_FAULT_SIGBUS result to user space.  And user space really
expected SIGSEGV, not SIGBUS.

To fix that case, we need to add a VM_FAULT_SIGSEGV, and teach all those
duplicate architecture fault handlers about it.  They all already have
the code to handle SIGSEGV, so it's about just tying that new return
value to the existing code, but it's all a bit annoying.

This is the mindless minimal patch to do this.  A more extensive patch
would be to try to gather up the mostly shared fault handling logic into
one generic helper routine, and long-term we really should do that
cleanup.

Just from this patch, you can generally see that most architectures just
copied (directly or indirectly) the old x86 way of doing things, but in
the meantime that original x86 model has been improved to hold the VM
semaphore for shorter times etc and to handle VM_FAULT_RETRY and other
"newer" things, so it would be a good idea to bring all those
improvements to the generic case and teach other architectures about
them too.
