Pull workqueue updates from Tejun Heo:
"Mostly patches to initialize workqueue subsystem earlier and get rid
of keventd_up().
The patches were headed for the last merge cycle but got delayed due
to a bug found late minute, which is fixed now.
Also, to help debugging, destroy_workqueue() is more chatty now on a
sanity check failure."

workqueue: move wq_numa_init() to workqueue_init()
workqueue: remove keventd_up()

Pull char/misc driver updates from Greg KH:
"Here's the big char/misc driver patches for 4.10-rc1. Lots of tiny
changes over lots of "minor" driver subsystems, the largest being some
new FPGA drivers. Other than that, a few other new drivers, but no new
driver subsystems added for this kernel cycle, a nice change.
All of these have been in linux-next with no reported issues"

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here's the new driver core patches for 4.10-rc1.
Big thing here is the nice addition of "functional dependencies" to
the driver core. The idea has been talked about for a very long time,
great job to Rafael for stepping up and implementing it. It's been
tested for longer than the 4.9-rc1 date, we held off on merging it
earlier in order to feel more comfortable about it.
Other than that, it's just a handful of small other patches, some good
cleanups to the mess that is the firmware class code, and we have a
test driver for the deferred probe logic.
All of these have been in linux-next for a while with no reported
issues"

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 clk updates from Stephen Boyd:
"This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds
another clk_get() variant. The rest of the changes are in drivers for
various SoCs, and we have a few bits for ARM shmobile architecture
code (dts and mach) due to the dependency we're breaking between
shmobile architecture code and its clk driver. Those shmobile bits
have also been pulled into arm-soc tree. Here's the summary:

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.
- finally support for crash recovery in the Qualcomm Wirelss subsystem
(used for WiFi/BT/FM on a number of platforms) and a number of bug
fixes and cleanups

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.

- The SX150x driver was deemed unfit for the GPIO subsystem and was
moved over to a combined GPIO+pinctrl driver in the pinctrl
subsystem.

Independent of whether the vma is for anonymous memory, some arches like
ppc64 would like to override pmd_move_must_withdraw().
One option is to encapsulate the vma_is_anonymous() check for general
architectures inside pmd_move_must_withdraw() so that is always called
and architectures that need unconditional overriding can override this
function. ppc64 needs to override the function when the MMU is
configured to use hash PTE's.

The bug in khugepaged fixed earlier in this series shows that radix tree
slot replacement is fragile; and it will become more so when not only
NULL<->!NULL transitions need to be caught but transitions from and to
exceptional entries as well. We need checks.
Re-implement radix_tree_replace_slot() on top of the sanity-checked
__radix_tree_replace(). This requires existing callers to also pass the
radix tree root, but it'll warn us when somebody replaces slots with
contents that need proper accounting (transitions between NULL entries,
real entries, exceptional entries) and where a replacement through the
slot pointer would corrupt the radix tree node counts.

In commit c5320926e370 ("mem-hotplug: introduce movable_node boot
option"), the memblock allocation direction is changed to bottom-up and
then back to top-down like this:
1. memblock_set_bottom_up(true), called by cmdline_parse_movable_node().
2. memblock_set_bottom_up(false), called by x86's numa_init().
Even though (1) occurs in generic mm code, it is wrapped by #ifdef
CONFIG_MOVABLE_NODE, which depends on X86_64.
This means that when we extend CONFIG_MOVABLE_NODE to non-x86 arches,
things will be unbalanced. (1) will happen for them, but (2) will not.
This toggle was added in the first place because x86 has a delay between
adding memblocks and marking them as hotpluggable. Since other arches
do this marking either immediately or not at all, they do not require
the bottom-up toggle.
So, resolve things by moving (1) from cmdline_parse_movable_node() to
x86's setup_arch(), immediately after the movable_node parameter has
been parsed.

Patch series "enable movable nodes on non-x86 configs", v7.
This patchset allows more configs to make use of movable nodes. When
CONFIG_MOVABLE_NODE is selected, there are two ways to introduce such
nodes into the system:
1. Discover movable nodes at boot. Currently this is only possible on
x86, but we will enable configs supporting fdt to do the same.
2. Hotplug and online all of a node's memory using online_movable. This
is already possible on any config supporting memory hotplug, not
just x86, but the Kconfig doesn't say so. We will fix that.
We'll also remove some cruft on power which would prevent (2).
This patch (of 5):
Remove the check which prevents us from hotplugging into an empty node.
The original commit b226e4621245 ("[PATCH] powerpc: don't add memory to

It is a workaround for an oops which no longer occurs.

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().

Some builds of m32r were failing as it tried to build few drivers which
needed dma but m32r is not having dma support. Objections were raised
when it was tried to make those drivers depend on HAS_DMA. So the next
best thing is to add dma support to m32r. dma_noop is a very simple dma
with 1:1 memory mapping.

Pull x86 microcode update from Ingo Molnar:
"The biggest change (by Borislav Petkov) is a thorough rewrite of the
Intel microcode loader and its interactions with the core code.
The biggest conceptual change is the decoupling of the microcode
loading on boot and application processors (which load the microcode
in different scenarios), so that both parse the input patches with as
few assumptions as possible - this also fixes various kernel address
space randomization bugs. (The AP side then goes on and caches the
result to improve boot performance.)
Since the AMD side already did this, this change also opened up the
path towards more unification/simplification of the core microcode
loading infrastructure:

Pull perf updates from Ingo Molnar:
"This update is pretty big and almost exclusively includes tooling
changes, because v4.9's LTS status forced to completion most of the
pending kernel side hardware enablement work and because we tried to
freeze core perf work a bit to give a time window for the fuzzing
efforts.
The diff is large mostly due to the JSON hardware event tables added
for Intel and Power8 CPUs. This was a popular feature request from
people working close to hardware and from the HPC community.
Tree size is big because this added the CPU event tables for over a
decade of Intel CPUs. Future changes for a CPU vendor alrady support
should be much smaller, as events for new models are added. The new
events are listed in 'perf list', for the CPU model the tool is
running on. If you find an interesting event it can be used as-is:
$ perf stat -a -e l2_lines_out.pf_clean sleep 1
Performance counter stats for 'system wide':
7,860,403 l2_lines_out.pf_clean
1.000624918 seconds time elapsed
The event lists can be searched the usual 'perf list' fashion for
(case insensitive) substrings as well:
$ perf list l2_lines_out
List of pre-defined events (to be used in -e):
cache:
l2_lines_out.demand_clean
[Clean L2 cache lines evicted by demand]
l2_lines_out.demand_dirty
[Dirty L2 cache lines evicted by demand]
l2_lines_out.dirty_all
[Dirty L2 cache lines filling the L2]
l2_lines_out.pf_clean
[Clean L2 cache lines evicted by L2 prefetch]
l2_lines_out.pf_dirty
[Dirty L2 cache lines evicted by L2 prefetch]
etc.
There's a few high level categories as well that can be listed:
'cache', 'floating point', 'frontend', 'memory', 'pipeline', 'virtual
memory'.
Existing generic events and workflows should work as-is.
The only kernel side change is a late breaking fix for an older
regression, related to Intel BTS, LBR and PT feature interaction.
On the tooling side there are three new tools / major features:
- The new 'perf c2c' tool provides means for Shared Data C2C/HITM
analysis.
This allows you to track down cacheline contention. The tool is
based on x86's load latency and precise store facility events
provided by Intel CPUs.
It was tested by Joe Mario and has proven to be useful, finding
some cacheline contentions. Joe also wrote a blog about c2c tool
with examples:
https://joemario.github.io/blog/2016/09/01/c2c-blog/
excerpt of the content on this site:
At a high level, “perf c2c” will show you:
* The cachelines where false sharing was detected.
* The readers and writers to those cachelines, and the offsets where those accesses occurred.
* The pid, tid, instruction addr, function name, binary object name for those readers and writers.
* The source file and line number for each reader and writer.
* The average load latency for the loads to those cachelines.
* Which numa nodes the samples a cacheline came from and which CPUs were involved.
Using perf c2c is similar to using the Linux perf tool today.
First collect data with “perf c2c record”, then generate a
report output with “perf c2c report”
There one finds extensive details on using the tool, with tips on
reducing the volume of samples while still capturing enough to do
its job. (Dick Fowles, Joe Mario, Don Zickus, Jiri Olsa)
- The new 'perf sched timehist' tool provides tailored analysis of
scheduling events.
Example usage:
perf sched record -- sleep 1
perf sched timehist
By default it shows the individual schedule events, including the
wait time (time between sched-out and next sched-in events for the
task), the task scheduling delay (time between wakeup and actually
running) and run time for the task:
time cpu task name wait time sch delay run time
[tid/pid] (msec) (msec) (msec)

Times are in msec.usec. (David Ahern, Namhyung Kim)
- Add CPU vendor hardware event tables:
Add JSON files with vendor event naming for Intel and Power8
processors, allowing users of tools like oprofile to keep using the
event names they are used to, as well as people reading vendor
documentation, where such naming is used. (Andi Kleen, Sukadev
Bhattiprolu)
You should see all the new events with 'perf list' and you should
be able to search them, for example 'perf list miss' will list all
the myriads of miss events.
Other tooling features added were:
- Cross-arch annotation support:
o Improve ARM support in the annotation code, affecting 'perf
annotate', 'perf report' and live annotation in 'perf top' (Kim
Phillips)
o Initial support for PowerPC in the annotation code (Ravi
Bangoria)
o Support AArch64 in the 'annotate' code, native/local and
cross-arch/remote (Kim Phillips)
- Allow considering just events in a given time interval, via the
'--time start.s.ms,end.s.ms' command line, added to 'perf kmem',
'perf report', 'perf sched timehist' and 'perf script' (David
Ahern)
- Add option to stop printing a callchain at one of a given group of
symbol names (David Ahern)
- Track memory freed in 'perf kmem stat' (David Ahern)
- Allow querying and setting .perfconfig variables (Taeung Song)
- Show branch information in callchains (predicted, TSX aborts, loop
iteractions, etc) (Jin Yao)
- Dynamicly change verbosity level by pressing 'V' in the 'perf
top/report' hists TUI browser (Alexis Berlemont)
- Implement 'perf trace --delay' in the same fashion as in 'perf
record --delay', to skip sampling workload initialization events
(Alexis Berlemont)
- Make vendor named events case insensitive in 'perf list', i.e.
'perf list LONGEST_LAT' works just the same as 'perf list
longest_lat' (Andi Kleen)
- Add unwinding support for jitdump (Stefano Sanfilippo)
Tooling infrastructure changes:
- Support linking perf with clang and LLVM libraries, initially
statically, but this limitation will be lifted and shared
libraries, when available, will be preferred to the static build,
that should, as with other features, be enabled explicitly (Wang
Nan)
- Add initial support (and perf test entry) for tooling hooks,
starting with 'record_start' and 'record_end', that will have as
its initial user the eBPF infrastructure, where perf_ prefixed
functions will be JITed and run when such hooks are called (Wang
Nan)
- Implement assorted libbpf improvements (Wang Nan)"
... and lots of other changes, features, cleanups and refactorings I
did not list, see the shortlog and the git log for details"

Pull locking updates from Ingo Molnar:
"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)
- Improve the rtmutex code a bit, in light of recent long lived
bugs/races. (Thomas Gleixner)
- Misc fixes, cleanups"
