When an ACPI node has both ACPI device nodes and ACPI data nodes,
acpi_get_next_subnode() will return the ACPI data nodes of its last
parsed child.
To avoid that, make acpi_get_next_subnode() go back to the original
ACPI device object when all of the device node children of it have
been found already.

The menu governor uses five different factors to pick the
idle state:
- the user configured latency_req
- the time until the next timer (next_timer_us)
- the typical sleep interval, as measured recently
- an estimate of sleep time by dividing next_timer_us by an observed factor
- a load corrected version of the above, divided again by load
Only the first three items are known with enough confidence that
we can use them to consider polling, instead of an actual CPU
idle state, because the cost of being wrong about polling can be
excessive power use.
The latter two are used in the menu governor's main selection
loop, and can result in choosing a shallower idle state when
the system is expected to be busy again soon.
This pushes a busy system in the "performance" direction of
the performance<>power tradeoff, when choosing between idle
states, but stays more strictly on the "power" state when
deciding between polling and C1.

The PM clocks framework requires clients to pass either a con-id or a
valid clk pointer in order to add a clock to a device. Add a new
function of_pm_clk_add_clks() to allows device clocks to be retrieved
from device-tree and populated for a given device. Note that it is
not necessary to make the compilation of this new function dependent
upon CONFIG_OF because there are stubs functions for the device-tree
APIs used.
In order to handle errors encountered when adding clocks from
device-tree, add a function pm_clk_remove_clk() to remove any clocks
(using a pointer to the clk structure) that have been added
successfully before the error occurred.

Pull libnvdimm updates from Dan Williams:
- Asynchronous address range scrub:
Given the capacities of next generation persistent memory devices a
scrub operation to find all poison may take 10s of seconds. We
want this scrub work to be done asynchronously with the rest of
system initialization, so we move it out of line from the NFIT
probing, i.e. acpi_nfit_add().
- Clear poison:
ACPI 6.1 introduces the ability to send "clear error" commands to
the ACPI0012:00 device representing the root of an "nvdimm bus".
Similar to relocating a bad block on a disk, this support clears
media errors in response to a write.
- Persistent memory resource tracking:
A persistent memory range may be designated as simply "reserved" by
platform firmware in the efi/e820 memory map. Later when the NFIT
driver loads it discovers that the range is "Persistent Memory".
The NFIT bus driver inserts a resource to advertise that
"persistent" attribute in the system resource tree for /proc/iomem
and kernel-internal usages.
- Miscellaneous cleanups and fixes:
Workaround section misaligned pmem ranges when allocating a struct
page memmap, fix handling of the read-only case in the ioctl path,
and clean up block device major number allocation.

Pull device mapper updates from Mike Snitzer:
- Most attention this cycle went to optimizing blk-mq request-based DM
(dm-mq) that is used exclussively by DM multipath:
- A stable fix for dm-mq that eliminates excessive context
switching offers the biggest performance improvement (for both
IOPs and throughput).
- But more work is needed, during the next cycle, to reduce
spinlock contention in DM multipath on large NUMA systems.
- A stable fix for a NULL pointer seen when DM stats is enabled on a DM
multipath device that must requeue an IO due to path failure.
- A stable fix for DM snapshot to disallow the COW and origin devices
from being identical. This amounts to graceful failure in the face
of userspace error because these devices shouldn't ever be identical.
- Stable fixes for DM cache and DM thin provisioning to address crashes
seen if/when their respective metadata device experiences failures
that cause the transition to 'fail_io' mode.
- The DM cache 'mq' policy is now an alias for the 'smq' policy. The
'smq' policy proved to be consistently better than 'mq'. As such
'mq', with all its complex user-facing tunables, has been eliminated.
- Improve DM thin provisioning to consistently return -ENOSPC once the
thin-pool's data volume is out of space.
- Improve DM core to properly handle error propagation if
bio_integrity_clone() fails in clone_bio().
- Other small cleanups and improvements to DM core.

It is possible, although unlikely, that probing will find the
phy_device for the first LMAC of a thunder BGX device, but then need
to fail with -EPROBE_DEFER on a subsequent LMAC. In this case, we
need to call put_device() on each of the phy_devices that were
obtained, but will be unused due to returning -EPROBE_DEFER.
Also, since we can break out of the probing loop early, we need to
explicitly call of_node_put() outside of the loop.

Locking ppp_mutex must be done before dereferencing file->private_data,
otherwise it could be modified before ppp_unattached_ioctl() takes the
lock. This could lead ppp_unattached_ioctl() to override ->private_data,
thus leaking reference to the ppp_file previously pointed to.
v2: lock all ppp_ioctl() instead of just checking private_data in
ppp_unattached_ioctl(), to avoid ambiguous behaviour.

The emac needs constant and very specific rate but the possible PLL-sources

This patch adds the following property for arc_emac.
1) phy-reset-gpios:
The phy-reset-gpio is an optional property for arc emac device tree boot.
Change the binding document to match the driver code.
2) phy-reset-duration:
Different boards may require different phy reset duration. Add property
phy-reset-duration for device tree probe, so that the boards that need
a longer reset duration can specify it in their device tree.
Anyway, we can add the above property for arc emac.

When driver has hit a parity event, HW can no longer write to host memory.
As a result, Tx completions cannot be written to the host SB memory, and
waiting for Tx completions eventually timeout.
As driver is willing to delay as much as 1-2 seconds per Tx queue for its
draining and this delay is sequential, the time to recover might greatly
lengthen needlessly in case the recovery is done under multi-connection
traffic.

drm/panel: Changes for v4.6-rc1
This contains a refactoring of parts of the DSI core to allow creating
DSI devices from non-DSI control busses (i.e. I2C, SPI, ...).
Other than that there's support for a couple of new panels as well as
a few cleanup patches.

drm/tegra: Changes for v4.6-rc1
Only two cleanups this time around. One fixes reference counting of
device tree nodes, the other changes the return value of a function
from an unsigned int to an int to reflect that it will return error
codes.
* tag 'drm/tegra/for-4.6-rc1' of http://anongit.freedesktop.org/git/tegra/linux:
gpu: host1x: Use a signed return type for do_relocs()
gpu: host1x: bus: Add missing of_node_put()
I hate doing this but it hurts my eyes to go over code that does not
comply with indentation rules. Only thing that is not only space change
is in atom.c all other files are space indentation issues.

Amdgpu doesn't support using scratch registers for fences any more.
So we won't see values like 0xdeadbeef as fence value any more.
v2: reschedule timer even if no change detected

Just wait for last fence instead of waiting for the sequence manually.
v2: don't use amdgpu_sched_jobs for the mask

Just keep all HW fences in a RCU protected array as a
first step to replace the wait queue.
v2: update commit message, move fixes into separate patch.

Fences must be freed RCU protected, otherwise the reservation_object_*_rcu()
functions can run into problems.
