833b5794e3 ARM: EXYNOS: reset Little cores when cpu is up
The cpu booting of exynos5422 has been still broken since we discussed
it in last year[1]. This patch is inspired from Odroid XU3
code (Actually, it was from samsung exynos vendor kernel)[2]. This weird
reset code was founded exynos5420 octa cores series SoCs and only
required for the first boot core is the Little core (Cortex A7).
Some of the exynos5420 boards and all of the exynos5422 boards will require
this code.

There is two ways to check the little core is the first cpu. One is
checking GPG2CON[1] GPIO value and the other is checking the cluster
number of the first cpu. I selected the latter because it's more easier
than the former.

216c59d65f drm/atomic-helper: Don't skip plane disabling on active CRTC
Since commit "drm/atomic-helper: Add option to update planes only on
active crtc" the drm_atomic_helper_commit_planes() function accepts an
active_only argument to skip updating planes when the associated CRTC is
inactive. Planes being disabled on an active CRTC are incorrectly
considered as associated with an inactive CRTC and are thus skipped,
preventing any plane disabling update from reaching drivers.

Fix it by checking the state of the CRTC stored in the old plane state
for planes being disabled.

4d73270192 scripts/kernel-doc: Replacing highlights hash by an array
The "highlight" code is very sensible to the order of the hash keys,
but the order of the keys cannot be predicted. It generates
faulty DocBook entries like:
	- @<function>device_for_each_child</function>

Sorting the result is not enough some times (as it's deterministic but
we can't control it).
We should use an array for that job, so we can guarantee that the order
of the regex execution on dohighlight is correct.

[jc: I think this is kind of papering around the real problem, that people
 are saying @function() when "function" is not a parameter.  But this makes
 things better than they were before, so...]

68f8666238 Documentation: Avoid creating man pages in source tree
Currently kernel-doc generates a dummy DocBook file when asked to
convert a C source file with no structured comments.  For an
out-of-tree build (objtree != srctree), the title of the output file
is the absolute path name of the C source file, which later results
in a manual page being created alongside the C source file.

Change the title to be a relative path.

23aebb3c05 scripts/kernel-doc: Processing -nofunc for functions only
Docproc processes the EXPORT_SYMBOL(f1) macro and uses -nofunc f1 to
avoid duplicated documentation in the next call.
It works for most of the cases, but there are some specific situations
where a struct has the same name of an already-exported function.

Current kernel-doc behavior ignores those structs and does not add them
to the final documentation. This patch fixes it.

This is unusual, the only case I've found is the drm_modeset_lock
(function and struct) defined in drm_modeset_lock.h and
drm_modeset_lock.c. Considering this, it should only affect the DRM
documentation by including struct drm_modeset_lock to the final Docbook.

6155a3cf11 staging: unisys: stop device registration before visorbus registration
In cases where visorbus is compiled directly into the kernel, if
visorbus registration fails for any reason, it is still possible for
other drivers to call visorbus_register_visor_driver(), which could
cause an oops. Prevent this by saving the result of the call to
create_bus() in a static variable, and return an error code when the bus
hasn't been registered successfully.

a6ee5ac15d staging/android: Update ION TODO per LPC discussion
We discussed a bit with the folks on the Cc: list below what to do
with ION. Two big take-aways:

- High-performance drivers (like gpus) always want to play tricks with
  coherency and will lie to the dma api (radeon, nouveau, i915 gpu
  drivers all do so in upstream). What needs to be done here is fill
  gaps in dma-buf so that we can do this without breaking the dma-api
  expections of other clients like v4l. The consesus is that hw won't
  stop needing these tricks anytime soon.

- Placement constraints for shared buffers won't be solved any other
  way than through something platform-specific like ion with
  platform-specific knowledge in userspace in something like gralloc.
  For general-purpose devices where this assumption would be painful
  for userspace (like servers) the consensus is that such devices will
  have proper MMUs where placement constraint handling is fairly
  irrelevant.

Hence it is reasonable to destage ion as-is without changing the
overall design to enable these use-cases and just fixing up a these
few fairly minor things. Since there won't relly be an open-source
userspace for ion (and hence drm maintainers won't take it) the
proposal is to eventually move it to drivers/android/ion.[hc]. Laura
would be ok with being maintainer once this is all done and ion is
destaged.

Note that Thiago is working on exposing the cpu cache flushing for
cpu access from userspace through mmaps so this is alread in progress.
Also adding him to the Cc: list.

v2: Add ION_IOC_IMPORT to the list of ioctl that probably should go.

caa470475d perf header: Fixup reading of HEADER_NRCPUS feature
The original patch introducing this header wrote the number of CPUs available
and online in one order and then swapped those values when reading, fix it.

Before:

  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 4
  # echo 0 > /sys/devices/system/cpu/cpu2/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 3
  # echo 0 > /sys/devices/system/cpu/cpu1/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 2

After the fix, bringing back the CPUs online:

  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 2
  # nrcpus avail : 4
  # echo 1 > /sys/devices/system/cpu/cpu2/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 3
  # nrcpus avail : 4
  # echo 1 > /sys/devices/system/cpu/cpu1/online
  # perf record usleep 1
  # perf report --header-only | grep 'nrcpus \(online\|avail\)'
  # nrcpus online : 4
  # nrcpus avail : 4

Commit 79ae3e66f8 (ARM: dts: sun4i: Add Iteaduino Plus A10) added a new
make target for the sun4i-a10-itead-iteaduino-plus dts file, but mistakenly
used .dts instead of the correct .dtb suffix.  This resulted in a build error
like:

        scripts/Makefile.dtbinst:42: target 'sun4i-a10-itead-iteaduino-plus.dts' doesn't match the target pattern

when doing a make dtbs_install.

Fix it to use the proper file name.

eaeef1ad9b ARM: dts: sunxi: Raise minimum CPU voltage for sun7i-a20 to meet SoC specifications
sun7i-a20.dtsi contains a cpufreq operating point at 0.9 volts. The minimum
CPU voltage for the Allwinner A20 SoC, however, is 1.0 volts. Thus, raise
the voltage for the lowest operating point to 1.0 volts in order to stay
within the SoC specifications. It is an undervolted setting that isn't
stable across all SoCs and boards out there.

b692cb83b1 ARM: pxa: ssp: Fix build error by removing originally incorrect DT binding
Commit 03fbf488ce ("spi: pxa2xx: Differentiate Intel LPSS types") caused
build error here because it removed the type LPSS_SSP and I didn't notice
the type was used here too.

I believe commit a6e56c28a1 ("ARM: pxa: ssp: add DT bindings") added it
accidentally by copying all enum pxa_ssp_type types from
include/linux/pxa2xx_ssp.h even LPSS_SSP was for Intel LPSS SPI devices.

Fix the build error by removing this incorrect binding.

adf3442cc8 ARM: pxa: fix DFI bus lockups on startup
After the conversion of pxa architecture to common clock framework, the
NAND clock can be disabled on startup if no nand driver claims it.

In this case, it happens that if the bootloader used the NAND and set
the DFI arbitration bit, the next access to a static memory controller
area, such as an ethernet card, the system bus will stall, and the core
will be stalled forever.

Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit
will be enabled the pxa3xx-nand driver on need anyway. The only left
requirement is that upon pxa3xx-nand removal, the bit should be cleared
before the clock is disabled.

0052b7dcf9 ALSA: pcm: remove structure member of 'struct snd_pcm_hwptr_log *' type because this structure had been removed
This structure was added by 4d96eb255c ('ALSA: pcm_lib - add possibility
to log last 10 DMA ring buffer positions') to store PCM pointers
information of latest 10 pointer movements (=XRUN_LOG_CNT). When
CONFIG_SND_PCM_XRUN_DEBUG is configured, 'struct snd_pcm_runtime' has
'hwptr_log' member with a pointer to the structure. When calling
xrun_log() in pcm_lib.c, the structure was allocated to the pointer.
When calling snd_pcm_detach_substream() in pcm.c, the allocated pointer
is released.

In f5914908a5 ('ALSA: pcm: Replace PCM hwptr tracking with tracepoints'),
the pointer logging is replaced with using Linux Kernel Tracepoints. The
structure was also removed, while it's just declared. The member and kfree
still remains.

This commit removes the member and related codes. I think this was
overlooked because it brings no errors/warnings to C compilers.

8f3e5684d3 perf/core: Drop PERF_EVENT_TXN
We currently use PERF_EVENT_TXN flag to determine if we are in the middle
of a transaction. If in a transaction, we defer the schedulability checks
from pmu->add() operation to the pmu->commit() operation.

Now that we have "transaction types" (PERF_PMU_TXN_ADD, PERF_PMU_TXN_READ)
we can use the type to determine if we are in a transaction and drop the
PERF_EVENT_TXN flag.

When PERF_EVENT_TXN is dropped, the cpuhw->group_flag on some architectures
becomes unused, so drop that field as well.

This is an extension of the Powerpc patch from Peter Zijlstra to s390,
Sparc and x86 architectures.
