Wei Ni 4d44cd4ae9 of: add notes of critical trips for soctherm
The "critical" type trip in thermal zone can be
set to SOC_THERM hardware, it can trigger shut down
or reset event from hardware.

Wei Ni c35095215a thermal: of-thermal: allow setting trip_temp on hardware
In current of-thermal, the .set_trip_temp only support to
set trip_temp for SW. But some sensors support to set
trip_temp on hardware, so that can trigger interrupt,
shutdown or any other events.
This patch adds .set_trip_temp() callback in
thermal_zone_of_device_ops{}, so that the sensor device can
use it to set trip_temp on hardware.

Wei Ni 65b6d57c24 thermal: tegra: split tegra_soctherm driver
Split most of the Tegra124 data and code into a Tegra124-specific
file.
Split most of the fuse-related code into a fuse-related source file.
This is in preparation for adding a Tegra210-specific driver in a
future patch.

Beyond the maintainability improvements, this is intended to separate
chip-specific ATE and characterization-related hacks into chip-specific
files, in the hopes that they won't pollute code for other chips.

Wei Ni 1c3bdc1627 thermal: tegra: get rid of PDIV/HOTSPOT hack
Get rid of T124-specific PDIV/HOTSPOT hack.
tegra-soctherm.c contained a hack to set the SENSOR_PDIV and
SENSOR_HOTSPOT_OFFSET registers - it just did two writes of
T124-specific opaque values.  Convert these into a form that can be
substituted on a per-chip basis, and into structure fields that have
at least some independent meaning.

 "Final set of -rc fixes for 4.6.

  I've collected up a number of patches that are all pretty small with
  the exception of only a couple.  The hfi1 driver has a number of
  important patches, and it is what really drives the line count of this
  pull request up.  These are all small and I've got this kernel built
  and running in the test lab (I have most of the hardware, I think nes
  is the only thing in this patch set that I can't say I've personally
  tested and have up and running).

  Summary:

   - A number of collected fixes for oopses, memory corruptions,
     deadlocks, etc.  All of these fixes are small (many only 5-10
     lines), obvious, and tested.

Tony Luck c4fc1956fa EDAC: i7core, sb_edac: Don't return NOTIFY_BAD from mce_decoder callback
Both of these drivers can return NOTIFY_BAD, but this terminates
processing other callbacks that were registered later on the chain.
Since the driver did nothing to log the error it seems wrong to prevent
other interested parties from seeing it. E.g. neither of them had even
bothered to check the type of the error to see if it was a memory error
before the return NOTIFY_BAD.

Linus Torvalds e1f14a5469 sound fixes for 4.6-rc6
Usually we get a big collection of fixes for ASoC once during rc.
 And this is it.
 
 At this time, most of fixes are about Intel Skylake ASoC driver, which
 is a new and still on-going development.  Along with it, a slight
 large LOC is seen in legacy HD-audio driver, but it's merely a code
 move to the upper layer.
 
 Other than that, the rest are small or trivial fixes to various
 drivers, in addition to an ASoC dapm debugfs code fix.

James Morse bdab42dfc9 kcov: don't trace the code coverage code
Kcov causes the compiler to add a call to __sanitizer_cov_trace_pc() in
every basic block.  Ftrace patches in a call to _mcount() to each
function it has annotated.

Letting these mechanisms annotate each other is a bad thing.  Break the
loop by adding 'notrace' to __sanitizer_cov_trace_pc() so that ftrace
won't try to patch this code.

This patch lets arm64 with KCOV and STACK_TRACER boot.
