NMI handler doesn't call set_irq_regs(), it's set only by normal IRQ.
Thus get_irq_regs() returns NULL or stale registers snapshot with IP/SP
pointing to the code interrupted by IRQ which was interrupted by NMI.
NULL isn't a problem: in this case watchdog calls dump_stack() and
prints full stack trace including NMI. But if we're stuck in IRQ
handler then NMI watchlog will print stack trace without IRQ part at
all.
This patch uses registers snapshot passed into NMI handler as arguments:
these registers point exactly to the instruction interrupted by NMI.

warning: `ratelimit' may be used uninitialized in this function
with gcc (4.1.2) and probably many other versions. The code actually is
correct but a bit twisted. Let's make it more straightforward and set
the default values at the beginning.

Pull MD updates from Shaohua Li:
- a raid5 writeback cache feature.
The goal is to aggregate writes to make full stripe write and reduce
read-modify-write. It's helpful for workload which does sequential
write and follows fsync for example. This feature is experimental and
off by default right now.
- FAILFAST support.
This fails IOs to broken raid disks quickly, so can improve latency.
It's mainly for DASD storage, but some patches help normal raid array
too.
- support bad block for raid array with external metadata
- AVX2 instruction support for raid6 parity calculation
- normalize MD info output
- add missing blktrace
- other bug fixes

This update includes the usual round of major driver updates (ncr5380,

an assortment of minor fixes, mostly in error legs or other not very

replacement for the old pci_msix_.. calls; this effectively makes IRQ
mapping generic for the drivers and allows blk_mq to use the

"The jfs piece of the current_time() series"
* tag 'jfs-4.10' of git://github.com/kleikamp/linux-shaggy:
fs: jfs: Replace CURRENT_TIME_SEC by current_time()
This reverts commit 6d31e3ba23.
This causes bootup problems for me both on my laptop and my desktop.
What they have in common is that they have NVMe disks with dm-crypt, but
it's not the same controller, so it's not controller-specific.
Jens does not see it on his machine (also NVMe), so it's presumably
something that triggers just on bootup. Possibly related to dm-crypt
and the fact that I mark my luks volume with "allow-discards" in
/etc/crypttab.
It's 100% repeatable for me, which made it fairly straightforward to
bisect the problem to this commit. Small mercies.
So we don't know what the reason is yet, but the revert is needed to get
things going again.

"One more patch from Adam added.
It makes libata skip probing for NCQ prio unless the feature is
explicitly requested by the user. This is necessary because some
controllers lock up after the optional feature is probed"
* 'for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
ata: avoid probing NCQ Prio Support if not explicitly requested
Previously, when the ata device was being initialized we were
probing for NCQ prio support by checking the identify information
and also checking the log page that holds information about ncq prio
support.
This caused an error on an Intel HBA so the code is now updated to
only probe for NCQ prio support when the sysfs variable controlling
NCQ prio support is enabled.
tj: Update formatting, switch to spin_[un]lock_irq() and update
locking a bit, use REVALIDATE instead of RESET, and return -EIO
instead of -EINVAL on config failure.

Pull libata updates from Tejun Heo:
- Adam added opt-in ATA command priority support.
- There are machines which hide multiple nvme devices behind an ahci
BAR. Dan Williams proposed a solution to force-switch the mode but
deemed too hackishd. People are gonna discuss the proper way to
handle the situation in nvme standard meetings. For now, detect and
warn about the situation.
- Low level driver specific changes.
Christoph Hellwig pipes in about the hidden nvme warning:
"I wish that was the case. We've pretty much agreed that we'll want to
implement it as a virtual PCIe root bridge, similar to Intels other
'innovation' VMD that we work around that way.
But Intel management has apparently decided that they don't want to
spend more cycles on this now that Lenovo has an optional BIOS that

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.

Recent dm-flakey fixes, to have reads error out during the "down"
interval, made it so that the previous read behaviour is no longer
available.
It is useful to have reads complete like normal but have writes error
out, so make it possible again with a new "error_writes" feature.

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.

Here's the "big" staging/iio pull request for 4.10-rc1.
Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver was
removed (got a "clean" driver for the same hardware through the netdev
tree), and some iio drivers were also dropped, but I think we ended up
adding a few thousand lines to the source tree in the end. Other than
that it's a lot of minor fixes all over the place, nothing major stands
out at all.
All of these have been in linux-next for a while. There will be a merge
conflict with Al's vfs tree in the lustre code, but the resolution for
that should be pretty simple, that too has been in linux-next.

Pull power management updates from Rafael Wysocki:
"Again, cpufreq gets more changes than the other parts this time (one
new driver, one old driver less, a bunch of enhancements of the
existing code, new CPU IDs, fixes, cleanups)
There also are some changes in cpuidle (idle injection rework, a
couple of new CPU IDs, online/offline rework in intel_idle, fixes and
cleanups), in the generic power domains framework (mostly related to
supporting power domains containing CPUs), and in the Operating
Performance Points (OPP) library (mostly related to supporting devices
with multiple voltage regulators)
In addition to that, the system sleep state selection interface is
modified to make it easier for distributions with unchanged user space
to support suspend-to-idle as the default system suspend method, some
issues are fixed in the PM core, the latency tolerance PM QoS
framework is improved a bit, the Intel RAPL power capping driver is
cleaned up and there are some fixes and cleanups in the devfreq
subsystem

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"

fbdev: remove current maintainer
- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing
this virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a
portion of a physical GPU. QEMU composes these mdevs into PCI
representations using the existing VFIO user API. This enables
both Intel KVM-GT support, which is also expected to arrive into
Linux mainline during the v4.10 merge window, as well as NVIDIA
vGPU, and also Channel I/O devices (aka CCW devices) for s390
virtualization support. (Kirti Wankhede, Neo Jia)

Introduces 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.

A quiet release for the regulator API, conference season must've been
slowing everyone down:
- A new interface allowing drivers to provide an interface for reading
a more detailed description of error conditions which allows devices
using these regulators to build
- ACPI support for the fixed voltage regulator.
- Cleanups for the TI TWL drivers to reduce code duplication.

- New driver for TI DA850/OMAP-L138/AM18XX pinconf
- The SX150x was moved over from the GPIO subsystem and
reimagined as a pin control driver with GPIO support
in a joint effort by three independent users of this
hardware. The result was amazingly good!
- New subdriver for the Oxnas OX820
Improvements:
- The sunxi driver now supports the generic pin control
bindings rather than the sunxi-specific. Add debouncing
support to the driver.
- Simplifications in pinctrl-single adding a generic parser.
- Two downstream fixes and move the Raspberry Pi BCM2835 over
to use the generic GPIOLIB_IRQCHIP.

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.
New features:
- Various cleanups to various drivers.
