020ba95dbb thermal: rockchip: Add the sort mode for adc value increment or decrement
The conversion table has the adc value and temperature.
In fact, the adc value only has the increment or decrement mode in
conversion table.

Moment, we can add the sort mode to be better support the *code_to_temp*
for differenr SoCs.

9b1b61cd8e ARM: OMAP2+: remove custom abort handler for t410
This is not needed anymore. Handling a potentially pending imprecise external
abort left behind by the bootloader is now done in a slightly safer way inside
the common ARM startup code.

With the recent changes to abort handling, this issue got fixed by 57df538085
("ARM: OMAP2+: Fix imprecise external abort caused by bogus SRAM init").

1d98b618cc thermal: rockchip: better to compatible the driver for different SoCs
The current driver is default to register the two thermal sensors
in probe since some SoCs maybe only have one sensor for thermal.

In some cases, the channel 0 is not always the cpu or gpu sensor.
So add the channel can be configured for sensors.

f514c2d842 drm/i915/gen9: flush DMC fw loading work during system suspend
Currently during system s/r we enable/disable DC6, so before we do so
make sure that the firmware loading is complete.

Note that whether we need to enable DC6 for S3/S4 is still open.  At
least the firmware program is lost during S3 and we need to reprogram it
after resuming. Until this is clarified we keep the current behavior and
enable/disable DC6.

During driver unload to ensure we dont have any pending task,
flush_work added to complete firmware loading task.

v1: Initial version.

v2: As per review comments from Daniel,
Removed flush_work from skl_set_power_well. As we have taken
power well refernece and rpm count during firmware loading
by using display_power_domain_get/put - this will always
ensure rpm will be blocked if firmware is not loaded.

8144ac59bd drm/i915: Use request_firmware and our own async work
Two benefits:
- We can use FW_LOADER_USERSPACE_FALLBACK.
- We can use flush_work to synchronize with the oustanding worker,
  which is a notch more obvious what it does than having a special
  completion.

The next patch will properly synchronize against the async loader in
the resume and unload code.

414b7999b8 drm/i915/gen9: Remove csr.state, csr_lock and related code.
This removes two anti-patterns:
- Locking shouldn't be used to synchronize with async work (of any
  form, whether callbacks, workers or other threads). This is what the
  mutex_lock/unlock seems to have been for in intel_csr_load_program.
  Instead ordering should be ensured with the generic
  wait_for_completion()/complete(). Or more specific functions
  provided by the core kernel like e.g.
  flush_work()/cancel_work_sync() in the case of synchronizing with a
  work item.

- Don't invent own completion like the following code did with the
  (already removed) wait_for(csr_load_status_get()) pattern - it's
  really hard to get these right when you want them to be _really_
  correct (and be fast) in all cases. Furthermore it's easier to read
  code using the well-known primitives than new ones using
  non-standard names.

Before enabling/disabling DC6 check if the firmware is loaded
successfully. This is guaranteed during runtime s/r, since otherwise we
don't enable RPM, but not during system s/r.

Note that it's still unclear whether we need to enable/disable DC6
during system s/r, until that's clarified, keep the current behavior and
enable/disable DC6.

Also after this patch there is a race during system s/r where the
firmware may not be loaded yet, that's addressed in an upcoming patch.

01a6908c0c drm/i915: use correct power domain for csr loading
Grabbing a runtime pm reference with intel_runtime_pm_get will only
prevent device D3. But dmc firmware is required even earlier (namely
for the skl power well 2).

Hence we need to grab a rpm reference higher up in the hierarchy. For
simplicity just grab the _INIT display power well. That's a bit too
much, but since the firmware loading task should completely fairly
quickly this won't be a real problem really.

ebae38d061 drm/i915/gen9: csr_init after runtime pm enable
Skl is fully dependent on dmc for going to low power state (dc5/dc6).
This requires a trigger from rpm. To ensure the dmc firmware
is available for runtime pm support rpm-reference-count is used
by not releasing the rpm reference if firmware loading is
not completed.

So moved the intel_csr_ucode_init call after runtime pm enable.

b1a14c6e40 drm/i915: refactor stepping info retrieval
Have only one if ladder for platforms and only one range check for
size. Makes it easier to handle new platforms. Remove the use of
negative return values in char, which might underflow to be positive for
some negative error codes.

No need to verify VMA belongs to GGTT since:

1. The function must return a normal VMA belonging to passed in VM.
2. There can only be one normal VMA for any VM.

909cadc6c8 ALSA: hda - Simplify phantom jack handling for HDMI/DP
The HDMI codec parser may create a phantom jack, but the helper
function snd_hda_jack_add_kctl() treats always as a normal jack.  This
is superfluous as the jack query is executed at each time the jack
sync is performed.

Since the HDMI codec parser is the only caller of this function, it's
easier to change back this directly calling the original
__snd_hda_jack_add_kctl() with phantom_jack parameter.

For bootloaders that support booting only ELF kernels and load only ELF
segments to memory there is no easy way to supply DTB without kernel
recompilation. For that purpose, create a section called .appended_dtb
that can be later updated with board-specific DTB using binutils e.g. at
kernel installation time.

d00d920338 MIPS: Clean up compat_siginfo_t
While mips can't use the generic compat_siginfo_t directly because
its si_code and si_errno are inverted, we can still make it as
close to the generic version as possible. This makes it easier
to update when new members are added to siginfo_t.

The main changes are adding a missing _sigsys union member and
eliminating the unused _irix_sigchld one.

cc25b994ac X.509: Fix the time validation [ver #2]
This fixes CVE-2015-5327.  It affects kernels from 4.3-rc1 onwards.

Fix the X.509 time validation to use month number-1 when looking up the
number of days in that month.  Also put the month number validation before
doing the lookup so as not to risk overrunning the array.

This can be tested by doing the following:
