Pull timer type cleanups from Thomas Gleixner:
"This series does a tree wide cleanup of types related to
timers/timekeeping.
- Get rid of cycles_t and use a plain u64. The type is not really
helpful and caused more confusion than clarity
- Get rid of the ktime union. The union has become useless as we use
the scalar nanoseconds storage unconditionally now. The 32bit
timespec alike storage got removed due to the Y2038 limitations
some time ago.
That leaves the odd union access around for no reason. Clean it up.
Both changes have been done with coccinelle and a small amount of
manual mopping up"

Pull SMP hotplug notifier removal from Thomas Gleixner:
"This is the final cleanup of the hotplug notifier infrastructure. The
series has been reintgrated in the last two days because there came a
new driver using the old infrastructure via the SCSI tree.
Summary:
- convert the last leftover drivers utilizing notifiers
- fixup for a completely broken hotplug user
- prevent setup of already used states
- removal of the notifiers
- treewide cleanup of hotplug state names
- consolidation of state space
There is a sphinx based documentation pending, but that needs review
from the documentation folks"

There is no point in having an extra type for extra confusion. u64 is
unambiguous.
Conversion was done with the following coccinelle script:
@rem@
@@
-typedef u64 cycle_t;
@fix@
typedef cycle_t;
@@
-cycle_t

When the state names got added a script was used to add the extra argument
to the calls. The script basically converted the state constant to a
string, but the cleanup to convert these strings into meaningful ones did
not happen.
Replace all the useless strings with 'subsys/xxx/yyy:state' strings which
are used in all the other places already.

The cpu hotplug support of this perf driver is broken in several ways:
1) It adds a instance before setting up the state.
2) The state for the instance is different from the state of the
callback. It's just a randomly chosen state.
3) The instance registration is not error checked so nobody noticed that
the call can never succeed.
4) The state for the multi install callbacks is chosen randomly and
overwrites existing state. This is now prevented by the core code so the
call is guaranteed to fail.
5) The error exit path in the init function leaves the instance registered
and then frees the memory which contains the enqueued hlist node.
6) The remove function is removing the state and not the instance.
Fix it by:
- Setting up the state before adding instances. Use a dynamically allocated
state for it.
- Installing instances after the state has been set up
- Removing the instance in the error path before freeing memory
- Removing the instance not the state in the driver remove callback
While at is use raw_cpu_processor_id(), because cpu_processor_id() cannot
be used in preemptible context, and set the driver data after successful
registration of the pmu.

The SoC hix5hd2 compatible string has the suffix "-gmac" and
we should not change it.
We should only add the generic compatible string "hisi-gmac-v1".

Pull virtio updates from Michael Tsirkin:
"virtio, vhost: new device, fixes, speedups
This includes the new virtio crypto device, and fixes all over the
place. In particular enabling endian-ness checks for sparse builds
found some bugs which this fixes. And it appears that everyone is in
agreement that disabling endian-ness sparse checks shouldn't be
necessary any longer.
So this enables them for everyone, and drops the __CHECK_ENDIAN__ and
__bitwise__ APIs.
IRQ handling in virtio has been refactored somewhat, the larger switch
to IRQ_SHARED will have to wait as it proved too aggressive"

Pull ARM DT updates from Arnd Bergmann:
"Lots of changes as usual, so I'm trying to be brief here. Most of the
new hardware support has the respective driver changes merged through

mvebu, allwinner, broadcom, exynos, zynq
- Continued fixes for W=1 dtc warnings
- The old STiH415/416 SoC support gets removed, these never made it
into products and have served their purpose in the kernel as a
template for teh newer chips from ST
- The exynos4415 dtsi file is removed as nothing uses it.

The use of DMA_ATTR_SKIP_CPU_SYNC was not consistent across all of the
DMA APIs in the arch/arm folder. This change is meant to correct that
so that we get consistent behavior.

Pull block layer updates from Jens Axboe:
"This is the main block pull request this series. Contrary to previous
release, I've kept the core and driver changes in the same branch. We
always ended up having dependencies between the two for obvious
reasons, so makes more sense to keep them together. That said, I'll
probably try and keep more topical branches going forward, especially
for cycles that end up being as busy as this one.
The major parts of this pull request is:
- Improved support for O_DIRECT on block devices, with a small
private implementation instead of using the pig that is
fs/direct-io.c. From Christoph.
- Request completion tracking in a scalable fashion. This is utilized
by two components in this pull, the new hybrid polling and the
writeback queue throttling code.
- Improved support for polling with O_DIRECT, adding a hybrid mode
that combines pure polling with an initial sleep. From me.
- Support for automatic throttling of writeback queues on the block
side. This uses feedback from the device completion latencies to
scale the queue on the block side up or down. From me.
- Support from SMR drives in the block layer and for SD. From Hannes
and Shaun.
- Multi-connection support for nbd. From Josef.
- Cleanup of request and bio flags, so we have a clear split between
which are bio (or rq) private, and which ones are shared. From
Christoph.
- A set of patches from Bart, that improve how we handle queue
stopping and starting in blk-mq.
- Support for WRITE_ZEROES from Chaitanya.
- Lightnvm updates from Javier/Matias.
- Supoort for FC for the nvme-over-fabrics code. From James Smart.
- A bunch of fixes from a whole slew of people, too many to name
here"

Pull remoteproc updates from Bjorn Andersson:
- introduce remoteproc "subdevice" support, which allows remoteproc
driver to associate devices to the "running" state of the remoteproc,
allowing devices to be probed and removed as the remote processor is
booted, shut down or recovering from a crash.
- handling of virtio device resources was improved, vring memory is now
allocated as part of other memory allocation. This ensures that all
vrings for all virtio devices are allocated before we boot the remote
processor.
- the debugfs mechanism for starting and stopping remoteproc instances
was replaced with a sysfs interface, also providing a mechanism for
specifying firmware to use by the instance. This allows user space to
load and boot use case specific firmware on remote processors.
- new drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
removal of the unused StE modem loader.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Luinus Walleij:
"Bulk GPIO changes for the v4.10 kernel cycle:
Core changes:
- Simplify threaded interrupt handling: instead of passing numbed
parameters to gpiochip_irqchip_add_chained() we create a new call:
gpiochip_irqchip_add_nested() so the two types are clearly
semantically different. Also make sure that all nested chips call
gpiochip_set_nested_irqchip() which is necessary for IRQ resend to
work properly if it happens.
- Return error on seek operations for the chardev.
- Clamp values set as part of gpio[d]_direction_output() so that
anything != 0 will be send down to the driver as "1" not the value
passed in.
- ACPI can now support naming of GPIO lines, hogs and holes in the
GPIO lists.
New drivers:
- The SX150x driver was deemed unfit for the GPIO subsystem and was
moved over to a combined GPIO+pinctrl driver in the pinctrl
subsystem.

Pull smp hotplug updates from Thomas Gleixner:
"This is the final round of converting the notifier mess to the state
machine. The removal of the notifiers and the related infrastructure
will happen around rc1, as there are conversions outstanding in other
trees.
The whole exercise removed about 2000 lines of code in total and in
course of the conversion several dozen bugs got fixed. The new
mechanism allows to test almost every hotplug step standalone, so
usage sites can exercise all transitions extensively.
There is more room for improvement, like integrating all the
pointlessly different architecture mechanisms of synchronizing,
setting cpus online etc into the core code"

Now that we check for page size change early in the loop, we can
partially revert e9d55e157034a ("mm: change the interface for
__tlb_remove_page").
This simplies the code much, by removing the need to track the last
address with which we adjusted the range. We also go back to the older
way of filling the mmu_gather array, ie, we add an entry and then check
whether the gather batch is full.

With commit e77b0852b551 ("mm/mmu_gather: track page size with mmu
gather and force flush if page size change") we added the ability to
force a tlb flush when the page size change in a mmu_gather loop. We
did that by checking for a page size change every time we added a page
to mmu_gather for lazy flush/remove. We can improve that by moving the
page size change check early and not doing it every time we add a page.
This also helps us to do tlb flush when invalidating a range covering
dax mapping. Wrt dax mapping we don't have a backing struct page and
hence we don't call tlb_remove_page, which earlier forced the tlb flush
on page size change. Moving the page size change check earlier means we
will do the same even for dax mapping.
We also avoid doing this check on architecture other than powerpc.
In a later patch we will remove page size check from tlb_remove_page().

"The tree got pretty big in this development cycle, but the net effect
is pretty good:
115 files changed, 673 insertions(+), 1522 deletions(-)
The main changes were:
- Rework and generalize the mutex code to remove per arch mutex
primitives. (Peter Zijlstra)
- Add vCPU preemption support: add an interface to query the
preemption status of vCPUs and use it in locking primitives - this
optimizes paravirt performance. (Pan Xinhui, Juergen Gross,
Christian Borntraeger)
- Introduce cpu_relax_yield() and remov cpu_relax_lowlatency() to
clean up and improve the s390 lock yielding machinery and its core
kernel impact. (Christian Borntraeger)
- Micro-optimize mutexes some more. (Waiman Long)
- Reluctantly add the to-be-deprecated mutex_trylock_recursive()
interface on a temporary basis, to give the DRM code more time to
get rid of its locking hacks. Any other users will be NAK-ed on
sight. (We turned off the deprecation warning for the time being to
not pollute the build log.) (Peter Zijlstra)

The function xen_guest_init is using __alloc_percpu with an alignment
which are not power of two.
However, the percpu allocator never supported alignments which are not power
of two and has always behaved incorectly in thise case.
Commit 3ca45a4 "percpu: ensure requested alignment is power of two"
introduced a check which trigger a warning [1] when booting linux-next
on Xen. But in reality this bug was always present.
This can be fixed by replacing the call to __alloc_percpu with
alloc_percpu. The latter will use an alignment which are a power of two.

The eLCDIF IP of the i.MX 7 SoC knows multiple clocks and lists them
separately:
Clock Clock Root Description
apb_clk MAIN_AXI_CLK_ROOT AXI clock
pix_clk LCDIF_PIXEL_CLK_ROOT Pixel clock
ipg_clk_s MAIN_AXI_CLK_ROOT Peripheral access clock
All of them are switched by a single gate, which is part of the
IMX7D_LCDIF_PIXEL_ROOT_CLK clock. Hence using that clock also for
the AXI bus clock (clock-name "axi") makes sure the gate gets
enabled when accessing registers.
There seem to be no separate AXI display clock, and the clock is
optional. Hence remove the dummy clock.
This fixes kernel freezes when starting the X-Server (which
disables/re-enables the display controller).
