Pull more ARM DT changes from Arnd Bergmann:
"Here are some final updates for ARM SoC specific dts files:
- The i.MX changes were sent relatively late, and had a dependency on
the clk tree, so I delayed that a bit. Support for the new i.MX6qp
SoC and a couple of new boards is added in this branch.
- Uniphier renames a few files to match the final product names that
were decided by the company, kudos to the kernel developer(s) for
getting support upstream before the product release. Also two
boards are added. The patches were posted early enough and nice
overall, but we forgot to apply them and decided to give it some
more time in linux-next
- at91 has two small bug fixes"

Pull thermal updates from Zhang Rui:
- Fix a regression where bogus trip points on some Lenovo laptops start
to screw up thermal control after commit 81ad4276b505 ("Thermal:
initialize thermal zone device correctly").
On these Lenovo laptops, a bogus passive trip point is reported,
which is 0 degree Celsius. Without commit 81ad4276b505, thermal zone
fails to set cooling devices to proper cooling state, which is a bug.
But with commit 81ad4276b505 applied, the processors are always
throttled on these Lenovo laptops because the current temperature is
always higher than the passive trip point.
Fix things to ignore such bogus trip points. (Zhang Rui)
- Introduce Mediatek thermal driver. (Sascha Hauer)
- Introduce devm_ versions of OF thermal sensor register API. (Laxman
Dewangan)
- Changes in Kconfigs to allow compile test on UM arch. (Krzysztof

Pull more rdma updates from Doug Ledford:
"Round two of 4.6 merge window patches.
This is a monster pull request. I held off on the hfi1 driver updates
(the hfi1 driver is intimately tied to the qib driver and the new
rdmavt software library that was created to help both of them) in my
first pull request. The hfi1/qib/rdmavt update is probably 90% of
this pull request. The hfi1 driver is being left in staging so that
it can be fixed up in regards to the API that Al and yourself didn't
like. Intel has agreed to do the work, but in the meantime, this
clears out 300+ patches in the backlog queue and brings my tree and
their tree closer to sync.
This also includes about 10 patches to the core and a few to mlx5 to
create an infrastructure for configuring SRIOV ports on IB devices.
That series includes one patch to the net core that we sent to netdev@
and Dave Miller with each of the three revisions to the series. We
didn't get any response to the patch, so we took that as implicit
approval.
Finally, this series includes Intel's new iWARP driver for their x722
cards. It's not nearly the beast as the hfi1 driver. It also has a
linux-next merge issue, but that has been resolved and it now passes
just fine.
Summary:
- A few minor core fixups needed for the next patch series
- The IB SRIOV series. This has bounced around for several versions.
Of note is the fact that the first patch in this series effects the
net core. It was directed to netdev and DaveM for each iteration
of the series (three versions total). Dave did not object, but did
not respond either. I've taken this as permission to move forward
with the series.
- The new Intel X722 iWARP driver
- A huge set of updates to the Intel hfi1 driver. Of particular
interest here is that we have left the driver in staging since it
still has an API that people object to. Intel is working on a fix,
but getting these patches in now helps keep me sane as the upstream
and Intel's trees were over 300 patches apart"

kcov provides code coverage collection for coverage-guided fuzzing
(randomized testing). Coverage-guided fuzzing is a testing technique
that uses coverage feedback to determine new interesting inputs to a
system. A notable user-space example is AFL
(http://lcamtuf.coredump.cx/afl/). However, this technique is not
widely used for kernel testing due to missing compiler and kernel
support.
kcov does not aim to collect as much coverage as possible. It aims to
collect more or less stable coverage that is function of syscall inputs.
To achieve this goal it does not collect coverage in soft/hard
interrupts and instrumentation of some inherently non-deterministic or
non-interesting parts of kernel is disbled (e.g. scheduler, locking).
Currently there is a single coverage collection mode (tracing), but the
API anticipates additional collection modes. Initially I also
implemented a second mode which exposes coverage in a fixed-size hash
table of counters (what Quentin used in his original patch). I've
dropped the second mode for simplicity.
This patch adds the necessary support on kernel side. The complimentary
compiler support was added in gcc revision 231296.
We've used this support to build syzkaller system call fuzzer, which has
found 90 kernel bugs in just 2 months:
https://github.com/google/syzkaller/wiki/Found-Bugs
We've also found 30+ bugs in our internal systems with syzkaller.
Another (yet unexplored) direction where kcov coverage would greatly
help is more traditional "blob mutation". For example, mounting a
random blob as a filesystem, or receiving a random blob over wire.
Why not gcov. Typical fuzzing loop looks as follows: (1) reset
coverage, (2) execute a bit of code, (3) collect coverage, repeat. A
typical coverage can be just a dozen of basic blocks (e.g. an invalid
input). In such context gcov becomes prohibitively expensive as
reset/collect coverage steps depend on total number of basic
blocks/edges in program (in case of kernel it is about 2M). Cost of
kcov depends only on number of executed basic blocks/edges. On top of
that, kernel requires per-thread coverage because there are always
background threads and unrelated processes that also produce coverage.
With inlined gcov instrumentation per-thread coverage is not possible.
kcov exposes kernel PCs and control flow to user-space which is
insecure. But debugfs should not be mapped as user accessible.
Based on a patch by Quentin Casasnovas.

FAT has long supported its own default file name encoding config
setting, separate from CONFIG_NLS_DEFAULT.
However, if UTF-8 encoded file names are desired FAT character set
should not be set to utf8 since this would make file names case
sensitive even if case insensitive matching is requested. Instead,
"utf8" mount options should be provided to enable UTF-8 file names in
FAT file system.
Unfortunately, there was no possibility to set the default value of this
option so on UTF-8 system "utf8" mount option had to be added manually
to most FAT mounts.
This patch adds config option to set such default value.

This document will describe OCFS2 online file check feature. OCFS2 is
often used in high-availaibility systems. However, OCFS2 usually
converts the filesystem to read-only when encounters an error. This may
not be necessary, since turning the filesystem read-only would affect
other running processes as well, decreasing availability.
Then, a mount option (errors=continue) is introduced, which would return
the -EIO errno to the calling process and terminate furhter processing
so that the filesystem is not corrupted further. The filesystem is not
converted to read-only, and the problematic file's inode number is
reported in the kernel log. The user can try to check/fix this file via
online filecheck feature.

He has an interesting series for muxes in the queue and agreed to look
after this part of the subsystem. Thank you, Peter, and welcome
again!
The octeon changes were applied pretty recently before the merge
window. I am aware. They are the first (and relatively simple)
patches of a larger overhaul to this driver. In case something goes
wrong with them, they are easy to fix (or revert). The advantage I
see is that they are out of the way, and I can concentrate on the next
block of patches. I really would like to apply the overhaul in
smaller batches to avoid regressions. And waiting a cycle for the
introductory patches seemed too much of a delay for me"

Pull MMC updates from Ulf Hansson:
"MMC core:
- Fix ABI regression of MMC BLK ioctl
- Remove the unused MMC_DATA_STREAM flag
- Enable asynchronous system PM for the host device
- Minor fixes and clean-ups
SDHCI host:
Throughout the years, the numbers of SDHCI variants have increased
and so has also the numbers of SDHCI callbacks/quirks. The purpose
of these callbacks/quirks were to enable SDHCI to deal with variant
specific requirements, but unfortunate this method didn't scale.
Instead we have ended up with a mess. Not only did the code become
suboptimal but also highly fragile.
Lately many discussions of how to move forward with SDHCI has taken
place at the MMC mailing list. Step by step, we aim to turn
SDHCI's common code into a set of library functions. This will
enable for optimizations and allow some of the existing callbacks
and quirks to be removed, which also should help to make the code
less fragile.
Therefore I am also really pleased to announce that Adrian Hunter
(Intel) has volunteered to step in as the maintainer for SDHCI.
Future wise, I hope the community around SDHCI will continue to
grow and that this release cycle can be the starting point of
moving SDHCI into a better shape. As a matter of fact, already in
this cycle the re-factoring has begun, but of course there are also
fixes and new features included. Some highlights:
- sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP

A mbigen hardware module can contain more than one device node. These device
nodes contain the same register definition.
mbigen_dev1:intc_dev1 {
...
reg = <0x0 0xc0080000 0x0 0x10000>;
...
};
mbigen_dev2:intc_dev2 {
...
reg = <0x0 0xc0080000 0x0 0x10000>;
...
};
In this case both devices try to request the same resource resulting in a
resource conflict.
To address this problem the devices need to be subnodes of the mbigen hardware
module, which then contains the unique register space.

Pull x86 protection key support from Ingo Molnar:
"This tree adds support for a new memory protection hardware feature
that is available in upcoming Intel CPUs: 'protection keys' (pkeys).
There's a background article at LWN.net:
https://lwn.net/Articles/643797/
The gist is that protection keys allow the encoding of
user-controllable permission masks in the pte. So instead of having a
fixed protection mask in the pte (which needs a system call to change
and works on a per page basis), the user can map a (handful of)
protection mask variants and can change the masks runtime relatively
cheaply, without having to change every single page in the affected
virtual memory range.
This allows the dynamic switching of the protection bits of large
amounts of virtual memory, via user-space instructions. It also
allows more precise control of MMU permission bits: for example the
executable bit is separate from the read bit (see more about that
below).
This tree adds the MM infrastructure and low level x86 glue needed for
that, plus it adds a high level API to make use of protection keys -
if a user-space application calls:
mmap(..., PROT_EXEC);
or
mprotect(ptr, sz, PROT_EXEC);
(note PROT_EXEC-only, without PROT_READ/WRITE), the kernel will notice
this special case, and will set a special protection key on this
memory range. It also sets the appropriate bits in the Protection
Keys User Rights (PKRU) register so that the memory becomes unreadable
and unwritable.
So using protection keys the kernel is able to implement 'true'
PROT_EXEC on x86 CPUs: without protection keys PROT_EXEC implies
PROT_READ as well. Unreadable executable mappings have security
advantages: they cannot be read via information leaks to figure out
ASLR details, nor can they be scanned for ROP gadgets - and they
cannot be used by exploits for data purposes either.
We know about no user-space code that relies on pure PROT_EXEC
mappings today, but binary loaders could start making use of this new
feature to map binaries and libraries in a more secure fashion.
There is other pending pkeys work that offers more high level system
call APIs to manage protection keys - but those are not part of this
pull request.
Right now there's a Kconfig that controls this feature
(CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS) that is default enabled
(like most x86 CPU feature enablement code that has no runtime
overhead), but it's not user-configurable at the moment. If there's
any serious problem with this then we can make it configurable and/or
flip the default"

the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

Pull cgroup updates from Tejun Heo:
"cgroup changes for v4.6-rc1. No userland visible behavior changes in
this pull request. I'll send out a separate pull request for the
addition of cgroup namespace support.
- The biggest change is the revamping of cgroup core task migration
and controller handling logic. There are quite a few places where
controllers and tasks are manipulated. Previously, many of those
places implemented custom operations for each specific use case
assuming specific starting conditions. While this worked, it makes
the code fragile and difficult to follow.
The bulk of this pull request restructures these operations so that
most related operations are performed through common helpers which
implement recursive (subtrees are always processed consistently)
and idempotent (they make cgroup hierarchy converge to the target
state rather than performing operations assuming specific starting
conditions). This makes the code a lot easier to understand,
verify and extend.
- Implicit controller support is added. This is primarily for using
perf_event on the v2 hierarchy so that perf can match cgroup v2
path without requiring the user to do anything special. The kernel
portion of perf_event changes is acked but userland changes are
still pending review.
- cgroup_no_v1= boot parameter added to ease testing cgroup v2 in
certain environments.
- There is a regression introduced during v4.4 devel cycle where
attempts to migrate zombie tasks can mess up internal object

Pull libata updates from Tejun Heo:
- ahci grew runtime power management support so that the controller can
be turned off if no devices are attached.
- sata_via isn't dead yet. It got hotplug support and more refined
workaround for certain WD drives.
- Misc cleanups. There's a merge from for-4.5-fixes to avoid confusing
conflicts in ahci PCI ID table.

Pull block driver updates from Jens Axboe:
"This is the block driver pull request for this merge window. It sits
on top of for-4.6/core, that was just sent out.
This contains:
- A set of fixes for lightnvm. One from Alan, fixing an overflow,
and the rest from the usual suspects, Javier and Matias.
- A set of fixes for nbd from Markus and Dan, and a fixup from Arnd
for correct usage of the signed 64-bit divider.
- A set of bug fixes for the Micron mtip32xx, from Asai.
- A fix for the brd discard handling from Bart.
- Update the maintainers entry for cciss, since that hardware has
transferred ownership.
- Three bug fixes for bcache from Eric Wheeler.
- Set of fixes for xen-blk{back,front} from Jan and Konrad.
- Removal of the cpqarray driver. It has been disabled in Kconfig
since 2013, and we were initially scheduled to remove it in 3.15.
- Various updates and fixes for NVMe, with the most important being:
- Removal of the per-device NVMe thread, replacing that with a
watchdog timer instead. From Christoph.
- Exposing the namespace WWID through sysfs, from Keith.
- Set of cleanups from Ming Lin.
- Logging the controller device name instead of the underlying
PCI device name, from Sagi.
- And a bunch of fixes and optimizations from the usual suspects
in this area"
