b400792732 Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Arnd Bergmann:
 "This is a rather large set of bugfixes, as we just returned from the
  Christmas break. Most of these are relatively unimportant fixes for
  regressions introduced during the merge window, and about half of the
  changes are for mach-omap2.

  A couple of patches are just cleanups and dead code removal that I
  would not normally have considered for merging after -rc2, but I
  decided to take them along with the fixes this time.

  Notable fixes include:

   - removing the skeleton.dtsi include broke a number of machines, and
     we have to put empty /chosen nodes back to be able to pass kernel
     command lines as before

   - enabling Samsung platforms no longer hardwires CONFIG_HZ to 200, as
     it had been for no good reason for a long time"

====================
rxrpc: Update tracing and proc interfaces

This set of patches fixes and extends tracing:

 (1) Fix the handling of enum-to-string translations so that external
     tracing tools can make use of it by using TRACE_DEFINE_ENUM.

 (2) Extend a couple of tracepoints to export some extra available
     information and add three new tracepoints to allow monitoring of
     received DATA packets, call disconnection and improper/implicit call
     termination.

and adds a bit more procfs-exported information:

 (3) Show a call's hard-ACK cursors in /proc/net/rxrpc_calls.

0e377f3b9a iio: Add gravity sensor support
Gravity sensor is a soft sensor, which derives value from
standard accelerometer device by filtering out the acceleration
which is not caused by gravity.

Gravity sensor provides a three dimensional vector indicating
the direction and magnitude of gravity. Typically, this sensor
is used to determine the device's relative orientation in space.
The units and the coordinate system is the same as the one used by
the acceleration sensor.
When a device is at rest, the output of the gravity sensor should
be identical to that of the accelerometer.

More information can be found in:
http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf

Gravity sensor and accelerometer have similar channels and
share channel usage ids. So the most of the code for accel_3d
can be reused.

c7858bf16c asm-prototypes: Clear any CPP defines before declaring the functions
The asm-prototypes.h file is used to provide dummy function declarations

memset/__memset on 32bit:

     this is varied by the slow-start algorithm.

 (2) Modify the rxrpc_rx_ack tracepoint to record more information from
     received ACK packets.

 (3) Add an rxrpc_rx_data tracepoint to record the information in DATA
     packets.

 (4) Add an rxrpc_disconnect_call tracepoint to record call disconnection,
     including the reason the call was disconnected.

 (5) Add an rxrpc_improper_term tracepoint to record implicit termination
     of a call by a client either by starting a new call on a particular
     connection channel without first transmitting the final ACK for the
     previous call.

b54a134a7d rxrpc: Fix handling of enums-to-string translation in tracing
Fix the way enum values are translated into strings in AF_RXRPC
tracepoints.  The problem with just doing a lookup in a normal flat array
of strings or chars is that external tracing infrastructure can't find it.
Rather, TRACE_DEFINE_ENUM must be used.

Also sort the enums and string tables to make it easier to keep them in
order so that a future patch to __print_symbolic() can be optimised to try
a direct lookup into the table first before iterating over it.

A couple of _proto() macro calls are removed because they refered to tables
that got moved to the tracing infrastructure.  The relevant data can be
found by way of tracing.

5952758101 dsa: mv88e6xxx: Optimise atu_get
Lookup in the ATU can be performed starting from a given MAC
address. This is faster than starting with the first possible MAC
address and iterating all entries.

Entries are returned in numeric order. So if the MAC address returned
is bigger than what we are searching for, we know it is not in the
ATU.

Using the benchmark provided by Volodymyr Bendiuga
<volodymyr.bendiuga@gmail.com>,

https://www.spinics.net/lists/netdev/msg411550.html

on an Marvell Armada 370 RD, the test to add a number of static fdb

888f97435a power: supply: axp288_fuel_gauge: Drop platform_data dependency
When the axp288_faul_gauge driver was originally merged, it was
merged with a dependency on some other driver providing platform
data for it.

However the battery-data-framework which should provide that data
never got merged, resulting in x86 tablets / laptops with an axp288
having no working battery monitor, as before this commit the driver
would simply return -ENODEV if there is no platform data.

This commit removes the dependency on the platform_data instead
checking that the firmware has initialized the fuel-gauge and
reading the info back from the pmic.

What is missing from the read-back info is the table to map raw adc
values to temperature, so this commit drops the temperature and
temperature limits properties. The min voltage, charge design and
model name info is also missing. Note that none of these are really
important for userspace to have.

All other functionality is preserved and actually made available
by this commit.

c6ef7fd40e vfio-mdev: fix non-standard ioctl return val causing i386 build fail
What appears to be a copy and paste error from the line above gets
the ioctl a ssize_t return value instead of the traditional "int".

The associated sample code used "long" which meant it would compile
for x86-64 but not i386, with the latter failing as follows:

  CC [M]  samples/vfio-mdev/mtty.o
samples/vfio-mdev/mtty.c:1418:20: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .ioctl          = mtty_ioctl,
                    ^
samples/vfio-mdev/mtty.c:1418:20: note: (near initialization for ‘mdev_fops.ioctl’)
cc1: some warnings being treated as errors

Since in this case, vfio is working with struct file_operations; as such:

    long (*unlocked_ioctl) (struct file *, unsigned int, unsigned long);
    long (*compat_ioctl) (struct file *, unsigned int, unsigned long);

...and so here we just standardize on long vs. the normal int that user
space typically sees and documents as per "man ioctl" and similar.

Directly merge drm-misc into drm-intel since Dave is on vacation and
we need the various drm-misc patches (fb format rework, drm mm fixes,
selftest framework and others). Also pulled back -rc2 in first to
resync with drm-intel-fixes and make sure I can reuse the exact rerere
solutions from drm-tip for safety, and because I'm lazy.

24835e442f drm: reference count event->completion
When writing the generic nonblocking commit code I assumed that
through clever lifetime management I can assure that the completion
(stored in drm_crtc_commit) only gets freed after it is completed. And
that worked.

I also wanted to make nonblocking helpers resilient against driver
bugs, by having timeouts everywhere. And that worked too.

Unfortunately taking boths things together results in oopses :( Well,
at least sometimes: What seems to happen is that the drm event hangs
around forever stuck in limbo land. The nonblocking helpers eventually
time out, move on and release it. Now the bug I tested all this
against is drivers that just entirely fail to deliver the vblank
events like they should, and in those cases the event is simply
leaked. But what seems to happen, at least sometimes, on i915 is that
the event is set up correctly, but somohow the vblank fails to fire in
time. Which means the event isn't leaked, it's still there waiting for
eventually a vblank to fire. That tends to happen when re-enabling the
pipe, and then the trap springs and the kernel oopses.

The correct fix here is simply to refcount the crtc commit to make
sure that the event sticks around even for drivers which only
sometimes fail to deliver vblanks for some arbitrary reasons. Since
crtc commits are already refcounted that's easy to do.

Add support for the SPI serial flash host controller found on many Intel
CPUs including Baytrail and Braswell. The SPI serial flash controller is
used to access BIOS and other platform specific information. By default the
driver exposes a single read-only MTD device but with a module parameter
"writeable=1" the MTD device can be made read-write which makes it possible
to upgrade BIOS directly from Linux.

1708ebc963 ipmr, ip6mr: add RTNH_F_UNRESOLVED flag to unresolved cache entries
While working with ipmr, we noticed that it is impossible to determine
if an entry is actually unresolved or its IIF interface has disappeared
(e.g. virtual interface got deleted). These entries look almost
identical to user-space when dumping or receiving notifications. So in
order to recognize them add a new RTNH_F_UNRESOLVED flag which is set when
sending an unresolved cache entry to user-space.

303b0d4be1 Merge branch 'for_4.11/net-next/rds_v3' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux
Santosh Shilimkar says:

====================
net: RDS updates

v2->v3:
- Re-based against latest net-next head.
- Dropped a user visible change after discussing with David Miller.
  It needs some more work to fully support old/new tools matrix.
- Addressed Dave's comment about bool usage in patch
  "RDS: IB: track and log active side..."

v1->v2:
Re-aligned indentation in patch 'RDS: mark few internal functions..."

Series consist of:
 - RDMA transport fixes for map failure, listen sequence, handler panic and
   composite message notification.
 - Couple of sparse fixes.
 - Message logging improvements for bind failure, use once mr semantics
   and connection remote address, active end point.
 - Performance improvement for RDMA transport by reducing the post send
   pressure on the queue and spreading the CQ vectors.
 - Useful statistics for socket send/recv usage and receive cache usage.
 - Additional RDS CMSG used by application to track the RDS message
   stages for certain type of traffic to find out latency spots.
   Can be enabled/disabled per socket.

e4781421e8 netfilter: merge udp and udplite conntrack helpers
udplite was copied from udp, they are virtually 100% identical.

This adds udplite tracker to udp instead, removes udplite module,
and then makes the udplite tracker builtin.

udplite will then simply re-use udp timeout settings.
It makes little sense to add separate sysctls, nowadays we have
fine-grained timeout policy support via the CT target.
