git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The bulk of this has been in multiple -next releases. There were a few
late breaking fixes and small features that got added in the last
couple days, but the whole set has received a build success
notification from the kbuild robot.
Change summary:
- Region media error reporting: A libnvdimm region device is the
parent to one or more namespaces. To date, media errors have been
reported via the "badblocks" attribute attached to pmem block
devices for namespaces in "raw" or "memory" mode. Given that
namespaces can be in "device-dax" or "btt-sector" mode this new
interface reports media errors generically, i.e. independent of
namespace modes or state.
This subsequently allows userspace tooling to craft "ACPI 6.1
Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error"
requests and submit them via the ioctl path for NVDIMM root bus
devices.
- Introduce 'struct dax_device' and 'struct dax_operations': Prompted
by a request from Linus and feedback from Christoph this allows for
dax capable drivers to publish their own custom dax operations.
This fixes the broken assumption that all dax operations are
related to a persistent memory device, and makes it easier for
other architectures and platforms to add customized persistent
memory support.
- 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
available for storage appliance applications to manually trigger
memory controllers to drain write-pending buffers that would
otherwise be flushed automatically by the platform ADR
(asynchronous-DRAM-refresh) mechanism at a power loss event.
Support for "locked" DIMMs is included to prevent namespaces from
surfacing when the namespace label data area is locked. Finally,
fixes for various reported deadlocks and crashes, also tagged for
-stable.
- ACPI / nfit driver updates: General updates of the nfit driver to
add DSM command overrides, ACPI 6.1 health state flags support, DSM
payload debug available by default, and various fixes.
Acknowledgements that came after the branch was pushed:
- commmit 565851c972b5 "device-dax: fix sysfs attribute deadlock":

Pull staging/IIO updates from Greg KH:
"Here is the big staging tree update for 4.12-rc1.
It's a big one, adding about 350k new lines of crap^Wcode, mostly all
in a big dump of media drivers from Intel. But there's other new
drivers in here as well, yet-another-wifi driver, new IIO drivers, and
a new crypto accelerator.
We also deleted a bunch of stuff, mostly in patch cleanups, but also
the Android ION code has shrunk a lot, and the Android low memory
killer driver was finally deleted, much to the celebration of the -mm
developers.
All of these have been in linux-next with a few build issues that will
show up when you merge to your tree"

Pull powerpc updates from Michael Ellerman:
"Highlights include:
- Larger virtual address space on 64-bit server CPUs. By default we
use a 128TB virtual address space, but a process can request access
to the full 512TB by passing a hint to mmap().
- Support for the new Power9 "XIVE" interrupt controller.
- TLB flushing optimisations for the radix MMU on Power9.
- Support for CAPI cards on Power9, using the "Coherent Accelerator
Interface Architecture 2.0".
- The ability to configure the mmap randomisation limits at build and
runtime.
- Several small fixes and cleanups to the kprobes code, as well as
support for KPROBES_ON_FTRACE.
- Major improvements to handling of system reset interrupts,
correctly treating them as NMIs, giving them a dedicated stack and
using a new hypervisor call to trigger them, all of which should
aid debugging and robustness.
- Many fixes and other minor enhancements.

drm/tegra: Changes for v4.12-rc1
This contains various fixes to the host1x driver as well as a plug for a
leak of kernel pointers to userspace.
A fairly big addition this time around is the Video Image Composer (VIC)
support that can be used to accelerate some 2D and image compositing
operations.
Furthermore the driver now supports FB modifiers, so we no longer rely
on a custom IOCTL to set those.
Finally this contains a few preparatory patches for Tegra186 support
which unfortunately didn't quite make it this time, but will hopefully
be ready for v4.13.

Lots of good stuff here, after many many many attempts, the kernel

wasn't an easy path for them at all.
There's also a staging driver that uses this new api, which is why
it's coming in through this tree.
Along with that, there's the usual huge number of changes for gadget
drivers, xhci, and other stuff. Johan also finally refactored pretty
much every driver that was looking at USB endpoints to do it in a
common way, which will help prevent any "badly-formed" devices from

Per the latest version of the "NVDIMM DSM Interface Example" [1], the
label data retrieval routine can report a "locked" status. In this case
all regions associated with that DIMM are disabled until the label area
is unlocked. Provide generic libnvdimm enabling for NVDIMMs with label
data area locking capabilities.

This is a preparation patch for handling locked nvdimm label regions, a
new concept as introduced by the latest DSM document on pmem.io [1]. A
future patch will leverage nvdimm_set_locked() at DIMM probe time to
flag regions that can not be enabled. There should be no functional
difference resulting from this change.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.12 kernel cycle.
Core changes:
- Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
This was a much discussed change. It affects use cases where people
write drivers that might or might not be using GPIO resources. I
have decided that this is the lesser evil right now.
- Make gpiod_count() behave consistently across different hardware
descriptions.
- Fix the syntax around open drain/open source to not infer active
high/low semantics.
New drivers:
- A new single-register fixed-direction framework driver for hardware
that have lines controlled by a single register that just work in
one direction (out or in), including IRQ support.
- Support the Fintek F71889A GPIO SuperIO controller.
- Support the National NI 169445 MMIO GPIO.
- Support for the X-Gene derivative of the DWC GPIO controller
- Support for the Rohm BD9571MWV-M PMIC GPIO controller.
- Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
and replace both the Gemini and the Moxa ART custom drivers with
this driver.
Driver improvements:
- A whole slew of drivers have their spinlocks chaned to raw
spinlocks as they provide irqchips, and thus we are progressing on
realtime compliance.
- Use devm_irq_alloc_descs() in a slew of drivers, getting managed
resources.
- Support for the embedded PWM controller inside the MVEBU driver.
- Debounce, open source and open drain support for the Aspeed driver.
- Misc smaller fixes like spelling and syntax and whatnot"

Due to the way I did the RX bitrate conversions in mac80211 with
spatch, going setting flags to setting the value, many drivers now
don't set the bandwidth value for 20 MHz, since with the flags it
wasn't necessary to (there was no 20 MHz flag, only the others.)
Rather than go through and try to fix up all the drivers, instead
renumber the enum so that 20 MHz, which is the typical bandwidth,
actually has the value 0, making those drivers all work again.
If VHT was hit used with a driver not reporting it, e.g. iwlmvm,
this manifested in hitting the bandwidth warning in
cfg80211_calculate_bitrate_vht().

Andrey reported a crash on init_net.ipv6.ip6_null_entry->rt6i_idev
since it is always NULL.
This is clearly wrong, we have code to initialize it to loopback_dev,
unfortunately the order is still not correct.
loopback_dev is registered very early during boot, we lose a chance
to re-initialize it in notifier. addrconf_init() is called after
ip6_route_init(), which means we have no chance to correct it.
Fix it by moving this initialization explicitly after
ipv6_add_dev(init_net.loopback_dev) in addrconf_init().

As I noted on the mailing list, it's easier than I originally thought to
create intentional collisions in the digested names. Unfortunately it's
not too easy to solve this, so for now just fix the comment to not lie.

This provides the infrastructure for schedulers to expose their internal
state through debugfs. We add a list of queue attributes and a list of
hctx attributes to struct elevator_type and wire them up when switching
schedulers.

Add missing seq_file.h header in blk-mq-debugfs.h
Signed-off-by: Jens Axboe <axboe@fb.com>

Originally, I tied debugfs registration/unregistration together with
sysfs. There's no reason to do this, and it's getting in the way of
letting schedulers define their own debugfs attributes. Instead, tie the
debugfs registration to the lifetime of the structures themselves.
The saner lifetimes mean we can also get rid of the extra mq directory
and move everything one level up. I.e., nvme0n1/mq/hctx0/tags is now
just nvme0n1/hctx0/tags.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"New features for this release:
- Pretty much a full rewrite of the processing of function plugins.
i.e. echo do_IRQ:stacktrace > set_ftrace_filter
- The rewrite was needed to add plugins to be unique to tracing
instances. i.e. mkdir instance/foo; cd instances/foo; echo
do_IRQ:stacktrace > set_ftrace_filter The old way was written very
hacky. This removes a lot of those hacks.
- New "function-fork" tracing option. When set, pids in the
set_ftrace_pid will have their children added when the processes
with their pids listed in the set_ftrace_pid file forks.
- Exposure of "maxactive" for kretprobe in kprobe_events
- Allow for builtin init functions to be traced by the function
tracer (via the kernel command line). Module init function tracing
will come in the next release.
- Added more selftests, and have selftests also test in an instance"

The memory controllers stat function names are awkwardly long and
arbitrarily different from the zone and node stat functions.
The current interface is named:
mem_cgroup_read_stat()
mem_cgroup_update_stat()
mem_cgroup_inc_stat()
mem_cgroup_dec_stat()
mem_cgroup_update_page_stat()
mem_cgroup_inc_page_stat()
mem_cgroup_dec_page_stat()
This patch renames it to match the corresponding node stat functions:
memcg_page_state() [node_page_state()]
mod_memcg_state() [mod_node_state()]
inc_memcg_state() [inc_node_state()]
dec_memcg_state() [dec_node_state()]
mod_memcg_page_state() [mod_node_page_state()]
inc_memcg_page_state() [inc_node_page_state()]
dec_memcg_page_state() [dec_node_page_state()]

The current duplication is a high-maintenance mess, and it's painful to
add new items or query memcg state from the rest of the VM.
This increases the size of the stat array marginally, but we should aim
to track all these stats on a per-cgroup level anyway.

Since commit 59dc76b0d4df ("mm: vmscan: reduce size of inactive file
list") we noticed bigger IO spikes during changes in cache access
patterns.
The patch in question shrunk the inactive list size to leave more room
for the current workingset in the presence of streaming IO. However,
workingset transitions that previously happened on the inactive list are
now pushed out of memory and incur more refaults to complete.
This patch disables active list protection when refaults are being
observed. This accelerates workingset transitions, and allows more of
the new set to establish itself from memory, without eating into the
ability to protect the established workingset during stable periods.
The workloads that were measurably affected for us were hit pretty bad
by it, with refault/majfault rates doubling and tripling during cache
transitions, and the machines sustaining half-hour periods of 100% IO
utilization, where they'd previously have sub-minute peaks at 60-90%.
Stateful services that handle user data tend to be more conservative
with kernel upgrades. As a result we hit most page cache issues with
some delay, as was the case here.
The severity seemed to warrant a stable tag.

On SPARSEMEM systems page poisoning is enabled after buddy is up,
because of the dependency on page extension init. This causes the pages
released by free_all_bootmem not to be poisoned. This either delays or
misses the identification of some issues because the pages have to
undergo another cycle of alloc-free-alloc for any corruption to be
detected.
Enable page poisoning early by getting rid of the PAGE_EXT_DEBUG_POISON
flag. Since all the free pages will now be poisoned, the flag need not
be verified before checking the poison during an alloc.
