Phil Reid e34d65696d stmmac: create of compatible mdio bus for stmmac driver
The DSA driver needs to be passed a reference to an mdio bus. Typically
the mac is configured to use a fixed link but the mdio bus still needs
to be registered so that it con configure the switch.
This patch follows the same process as the altera tse ethernet driver for
creation of the mdio bus.

Dominik Dingel a3a92c31bf KVM: s390: fix mismatch between user and in-kernel guest limit
While the userspace interface requests the maximum size the gmap code
expects to get a maximum address.

This error resulted in bigger page tables than necessary for some guest
sizes, e.g. a 2GB guest used 3 levels instead of 2.

At the same time we introduce KVM_S390_NO_MEM_LIMIT, which allows in a
bright future that a guest spans the complete 64 bit address space.

We also switch to TASK_MAX_SIZE for the initial memory size, this is a
cosmetic change as the previous size also resulted in a 4 level pagetable
creation.

With device tree it is no more possible to reset the PHY at board
level. Furthermore, doing in the driver allow to power down the PHY when
the network interface is no more used.

This reset can't be done at the PHY driver level. The PHY must be able to
answer the to the mii bus scan to let the kernel creating a PHY device.

The patch introduces a new optional property "phy-reset-gpios" inspired
from the one use for the FEC.

The ADF7242 requires an add-on firmware for the automatic IEEE 802.15.4
operating modes. The firmware file is currently made available on the

Sami Tolvanen a739ff3f54 dm verity: add support for forward error correction
Add support for correcting corrupted blocks using Reed-Solomon.

This code uses RS(255, N) interleaved across data and hash
blocks. Each error-correcting block covers N bytes evenly
distributed across the combined total data, so that each byte is a
maximum distance away from the others. This makes it possible to
recover from several consecutive corrupted blocks with relatively
small space overhead.

In addition, using verity hashes to locate erasures nearly doubles
the effectiveness of error correction. Being able to detect
corrupted blocks also improves performance, because only corrupted
blocks need to corrected.

For a 2 GiB partition, RS(255, 253) (two parity bytes for each
253-byte block) can correct up to 16 MiB of consecutive corrupted
blocks if erasures can be located, and 8 MiB if they cannot, with
16 MiB space overhead.

Simon Horman 0b2eed4987 dmaengine: usb-dmac: Document SoC specific compatibility strings
In general Renesas hardware is not documented to the extent where the
relationship between IP blocks on different SoCs can be assumed although
they may appear to operate the same way. Furthermore the documentation
typically does not specify a version for individual IP blocks. For these
reasons a convention of using the SoC name in place of a version and
providing SoC-specific compatibility strings has been adopted.

Although not universally liked this convention is used in the bindings for
most drivers for Renesas hardware. The purpose of this patch is to
update the Renesas USB DMA Controller driver to follow this convention.

Peter Maydell d9f43babb9 Documentation: dt: Add bindings for Secure-only devices
The existing device tree bindings assume that we are only trying to
describe a single address space with a device tree (for ARM, either
the Normal or the Secure world). Some uses for device tree need to
describe both Normal and Secure worlds in a single device tree. Add
documentation of how to do this, by adding extra properties which
describe when a device appears differently in the two worlds or when
it only appears in one of them.

The binding describes the general principles for adding new
properties describing the secure world, but for now we only need a
single new property, "secure-status", which can be used to annotate
devices to indicate that they are only visible in one of the two
worlds.

The primary expected use of this binding is for a virtual machine
like QEMU to describe the VM layout to a TrustZone aware firmware
(which would then use the secure-only devices itself, and pass the DT
on to a kernel running in the non-secure world, which ignores the
secure-only devices and uses the rest).

Al Viro 6b2553918d replace ->follow_link() with new method that could stay in RCU mode
new method: ->get_link(); replacement of ->follow_link().  The differences
are:
	* inode and dentry are passed separately
	* might be called both in RCU and non-RCU mode;
the former is indicated by passing it a NULL dentry.
	* when called that way it isn't allowed to block
and should return ERR_PTR(-ECHILD) if it needs to be called
in non-RCU mode.

It's a flagday change - the old method is gone, all in-tree instances
converted.  Conversion isn't hard; said that, so far very few instances
do not immediately bail out when called in RCU mode.  That'll change
in the next commits.

Brian Norris e488ca9f8d doc: dt: mtd: partitions: add compatible property to "partitions" node
As noted here [1], there are potentially future conflicts if we try to
use MTD's "partitions" subnode to describe anything besides just the
fixed-in-the-device-tree partitions currently described in this
document. Particularly, there was a proposal to use this node for the
AFS parser too.

It can pose a (small) problem to try to differentiate the following
nodes:

	// using binding as currently specified
	partitions {
		#address-cells = <x>;
		#size-cells = <y>;
		partition@0 {
			...;
		};
	};

and

	// proposed future binding
	partitions {
		compatible = "arm,arm-flash-structure";
	};

It's especially difficult if other uses of this node start having
subnodes.

So, since the "partitions" node is new in v4.4, let's fixup the binding
before release so that it requires a compatible property, so it's much
clearer to distinguish. e.g.:

	// proposed
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <x>;
		#size-cells = <y>;
		partition@0 {
			...;
		};
	};

Tejun Heo 82607adcf9 workqueue: implement lockup detector
Workqueue stalls can happen from a variety of usage bugs such as
missing WQ_MEM_RECLAIM flag or concurrency managed work item
indefinitely staying RUNNING.  These stalls can be extremely difficult
to hunt down because the usual warning mechanisms can't detect
workqueue stalls and the internal state is pretty opaque.

To alleviate the situation, this patch implements workqueue lockup
detector.  It periodically monitors all worker_pools periodically and,
if any pool failed to make forward progress longer than the threshold
duration, triggers warning and dumps workqueue state as follows.

 BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=0 stuck for 31s!

   pwq 0: cpus=0 node=0 flags=0x0 nice=0 active=1/1
     pending: cgroup_pidlist_destroy_work_fn
 ...

The detection mechanism is controller through kernel parameter
workqueue.watchdog_thresh and can be updated at runtime through the
sysfs module parameter file.

not depend on reporters capable of rebuilding the driver.

Andi Kleen 7f47d8cc03 x86, tracing, perf: Add trace point for MSR accesses
For debugging low level code interacting with the CPU it is often
useful to trace the MSR read/writes. This gives a concise summary of
PMU and other operations.

perf has an ad-hoc way to do this using trace_printk, but it's
somewhat limited (and also now spews ugly boot messages when enabled)

Instead define real trace points for all MSR accesses.

This adds three new trace points: read_msr and write_msr and rdpmc.

They also report if the access faulted (if *_safe is used)

This allows filtering and triggering on specific MSR values, which
allows various more advanced debugging techniques.

All the values are well defined in the CPU documentation.

The trace can be post processed with
Documentation/trace/postprocess/decode_msr.py to add symbolic MSR
names to the trace.

I only added it to native MSR accesses in C, not paravirtualized or in
entry*.S (which is not too interesting)

Originally the patch kit moved the MSRs out of line.  This uses an
alternative approach recommended by Steven Rostedt of only moving the
trace calls out of line, but open coding the access to the jump label.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2015-12-03

This series contains updates to ixgbe, i40e/i40evf, MAINTAINERS and e100.txt

Alex provides a fix for ixgbe where enabling SR-IOV and then bringing the
interface up was resulting in the PF MAC addresses getting into a bad state.
The workaround for this issue is to bring up the interface first and then
enable SR-IOV as this will trigger the reset in the existing code.

I clean up legacy license stuff in the e100.txt documentation and then
update the maintainers/reviewers list for our drivers.

Jesse fixes an issue with the i40e/i40evf drivers, where if the driver were
to happen to have a mutex held while the i40e_init_adminq() call was called,
the init_adminq might inadvertently call mutex_init on a lock that was held
which is a violation of the calling semantices.

Because RCU-sched expedited grace periods now use IPIs and interact

Paul E. McKenney 5a9be7c628 rcu: Add rcu_normal kernel parameter to suppress expediting
Although expedited grace periods can be quite useful, and although their
OS jitter has been greatly reduced, they can still pose problems for
extreme real-time workloads.  This commit therefore adds a rcu_normal
kernel boot parameter (which can also be manipulated via sysfs)
to suppress expedited grace periods, that is, to treat requests for
expedited grace periods as if they were requests for normal grace periods.
If both rcu_expedited and rcu_normal are specified, rcu_normal wins.
This means that if you are relying on expedited grace periods to speed up
boot, you will want to specify rcu_expedited on the kernel command line,
and then specify rcu_normal via sysfs once boot completes.

if LPM is enabled, although it declares the LPM capability.  Users
won't be able to use this kind of devices, until someone puts them
in the kernel blacklist and gets the kernel upgraded.

This patch adds a sysfs node to permit or forbit USB3 LPM U1 or U2
entry for a port. The settings apply to both before and after device
enumeration. Supported values are "0" - neither u1 nor u2 permitted,
"u1" - only u1 is permitted, "u2" - only u2 is permitted, "u1_u2" -
both u1 and u2 are permitted. With this interface, users can use an
LPM-unfriendly USB device on a released Linux kernel.

Lu Baolu bf5ce5bf3c usb: core: lpm: fix usb3_hardware_lpm sysfs node
Commit 655fe4effe ("usbcore: add sysfs support to xHCI usb3
hardware LPM") introduced usb3_hardware_lpm sysfs node. This
doesn't show the correct status of USB3 U1 and U2 LPM status.

This patch fixes this by replacing usb3_hardware_lpm with two
nodes, usb3_hardware_lpm_u1 (for U1) and usb3_hardware_lpm_u2
(for U2), and recording the U1/U2 LPM status in right places.

This patch should be back-ported to kernels as old as 4.3,
that contains Commit 655fe4effe ("usbcore: add sysfs support
to xHCI usb3 hardware LPM").

Nikolay Aleksandrov 02fff96a79 net: add support for netdev notifier error injection
This module allows to insert errors in some of netdevice's notifier
events. All network drivers use these notifiers to signal various events
and to check if they are allowed, e.g. PRECHANGEMTU and CHANGEMTU
afterwards. Until recently I had to run failure tests by injecting
a custom module, but now this infrastructure makes it trivial to test
these failure paths. Some of the recent bugs I fixed were found using
this module.
Here's an example:
 $ cd /sys/kernel/debug/notifier-error-inject/netdev
 $ echo -22 > actions/NETDEV_CHANGEMTU/error
 $ ip link set eth0 mtu 1024
 RTNETLINK answers: Invalid argument

Alan Stern 0290cc9f04 USB: limit usbfs snooping of URB contents
The usbfs_snoop facility can be very useful for debugging problems
involving usbfs.  However, it always prints out the entire contents of
every URB.  When dealing with large quantities of data, this can be
less than helpful.

This patch ameliorates the situation by adding a module parameter to
usbcore for controlling the maximum number of bytes to print when
snooping an URB.  This makes debugging much easier.  For backward
compatibility, the default value is set unreasonably high.

Greg Kroah-Hartman f3cf3fb7ec First set of new device support, features and cleanups for IIO in the 4.5 cycle
Usual mixed bag, but the big item perhaps in this series is the DMA buffer
 support added by Lars-Peter Clausen. It's been in the works for a long time
 and it will be interesting to see what hardware support shows up now that
 this is available.
 
 New core features + associate cleanup.
 * Add generic DMA buffer infrastructure
 * Add a DMAengine framework based buffer
  Also associated minor changes.
    - Set the device buffer watermark based on the minimum watermark for all
      attached buffers rather than just the 'primary' one.
    - iio_buffer_init - only set the watermark default if one hasn't already
      been provided.  This allows simple support for devices with a fixed
      watermark.
    - read only attribute for watermark on fixed watermark devices.
    - add explicit buffer enable/disable callbacks to allow the buffer to
      do more than trivial actions when it is being turned on and off.
 * IIO_VAL_INT support in write_raw_get_fmt function.
 
 New device support
 * Freescale MMA7455/7456L accelerometers
 * Memsic MXC6255XC accelerometer
 * ST lis2dh12 accelerometer
 * TI ADS8688 ADC
 * TI Palamas (twl6035/7) gpadc
 
 New driver features
 * mma8452
   - support either of the available interrupt pins to cope with the case
     where board layout has lead to a particular one being connected.
 
 Staging graduation
 * Dummy driver
   - this driver acts as both an example and a test device for those with
     out hardware to develop userspace code against.
 
 Cleanups and minor bits and bobs.
 * treewide
   - Sort out the ordering of iio_device_register/unregister vs runtime
     pm function calls so that it's all nice and consistent and not race
     prone.
   - Check sscanf return values.  None of the cases will actually happen as
     the strings are supplied internally, but best to be consistent on this.
 * ad7780
   - switch over to the gpio descriptor interface and remove the now unused
     platform data which gets rid of a header entirely.
 * ad7793
   - drop a pointless else statement.
 * at91_adc
   - Swap kmalloc_array in for a kmalloc doing the same job.
 * dummy
   - get rid of some commented out lines that snuck in during the move of
     the driver.
 * lm3533-als
   - Print an error message on provision of an invalid resistance.
 * mcp320x
   - Add compatible strings with vendor prefix and deprecate those with
     no vendor prefix.
 * mxs-lradc
   - Use BIT macro in various places rather than shifted ones.
 * pa12203001
   - Power off the chip if the registration fails.
 * pulsedlight-lidar-lite
   - add runtime PM support.
 * xilinx XADC
   - constify an iio_buffer_setup_ops structure.

In eDMA the events are directly mapped to a DMA channel (for example DMA
event 14 can only be handled by DMA channel 14). If the memcpy is enabled
on the eDMA, there is a possibility that the crossbar driver would assign
DMA event number already allocated in eDMA for memcpy. Furthermore the
eDMA can be shared with DSP in which case the crossbar driver should also
avoid mapping xbar events to DSP used event numbers (or channels).

Takuya Yoshikawa 77fbbbd2f0 KVM: x86: MMU: Consolidate BUG_ON checks for reverse-mapped sptes
At some call sites of rmap_get_first() and rmap_get_next(), BUG_ON is
placed right after the call to detect unrelated sptes which must not be
found in the reverse-mapping list.

Move this check in rmap_get_first/next() so that all call sites, not
just the users of the for_each_rmap_spte() macro, will be checked the
same way.

One thing to keep in mind is that kvm_mmu_unlink_parents() also uses
rmap_get_first() to handle parent sptes.  The change will not break it
because parent sptes are present, at least until drop_parent_pte()
actually unlinks them, and not mmio-sptes.

Andrey Smetanin 5c919412fe kvm/x86: Hyper-V synthetic interrupt controller
SynIC (synthetic interrupt controller) is a lapic extension,
which is controlled via MSRs and maintains for each vCPU
 - 16 synthetic interrupt "lines" (SINT's); each can be configured to
   trigger a specific interrupt vector optionally with auto-EOI
   semantics
 - a message page in the guest memory with 16 256-byte per-SINT message
   slots
 - an event flag page in the guest memory with 16 2048-bit per-SINT
   event flag areas

The host triggers a SINT whenever it delivers a new message to the
corresponding slot or flips an event flag bit in the corresponding area.
The guest informs the host that it can try delivering a message by
explicitly asserting EOI in lapic or writing to End-Of-Message (EOM)
MSR.

The userspace (qemu) triggers interrupts and receives EOM notifications
via irqfd with resampler; for that, a GSI is allocated for each
configured SINT, and irq_routing api is extended to support GSI-SINT
mapping.

Changes v4:
* added activation of SynIC by vcpu KVM_ENABLE_CAP
* added per SynIC active flag
* added deactivation of APICv upon SynIC activation

Changes v3:
* added KVM_CAP_HYPERV_SYNIC and KVM_IRQ_ROUTING_HV_SINT notes into
docs

Changes v2:
* do not use posted interrupts for Hyper-V SynIC AutoEOI vectors
* add Hyper-V SynIC vectors into EOI exit bitmap
* Hyper-V SyniIC SINT msr write logic simplified

Linus Torvalds 4ce01c518e Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe:
 "A round of fixes/updates for the current series.

  This looks a little bigger than it is, but that's mainly because we
  pushed the lightnvm enabled null_blk change out of the merge window so
  it could be updated a bit.  The rest of the volume is also mostly
  lightnvm.  In particular:

   - Lightnvm.  Various fixes, additions, updates from Matias and
     Javier, as well as from Wenwei Tao.

   - NVMe:
        - Fix for potential arithmetic overflow from Keith.
        - Also from Keith, ensure that we reap pending completions from
          a completion queue before deleting it.  Fixes kernel crashes
          when resetting a device with IO pending.
        - Various little lightnvm related tweaks from Matias.

   - Fixup flushes to go through the IO scheduler, for the cases where a
     flush is not required.  Fixes a case in CFQ where we would be
     idling and not see this request, hence not break the idling.  From
     Jan Kara.

   - Use list_{first,prev,next} in elevator.c for cleaner code.  From
     Gelian Tang.

   - Fix for a warning trigger on btrfs and raid on single queue blk-mq
     devices, where we would flush plug callbacks with preemption
     disabled.  From me.

   - A mac partition validation fix from Kees Cook.

   - Two merge fixes from Ming, marked stable.  A third part is adding a
     new warning so we'll notice this quicker in the future, if we screw
     up the accounting.

   - Cleanup of thread name/creation in mtip32xx from Rasmus Villemoes"

Viresh Kumar 754dcf35f3 PM / OPP: Rename OPP nodes as opp@<opp-hz>
It would be better to name OPP nodes as opp@<opp-hz> as that will ensure
that multiple DT nodes don't contain the same frequency. Of course we
expect the writer to name the node with its opp-hz frequency and not any
other frequency.

And that will let the compile error out if multiple nodes are using the
same opp-hz frequency.

Viresh Kumar ffdb8cc7a2 PM / OPP: Add {opp-microvolt|opp-microamp}-<name> binding
Depending on the version of hardware or its properties, which are only
known at runtime, various properties of the OPP can change. For example,
an OPP with frequency 1.2 GHz, may have different voltage/current
requirements based on the version of the hardware it is running on.

In order to not replicate the same OPP tables for varying values of all
such fields, this commit introduces the concept of opp-property-<name>.
The <name> can be chosen by the platform at runtime, and OPPs will be
initialized depending on that name string. Currently support is extended
for the following properties:
- opp-microvolt-<name>
- opp-microamp-<name>

If the name string isn't provided by the platform, or if it is provided
but doesn't match the properties present in the OPP node, we will fall
back to the original properties without the -<name> string, if they are
available.

Viresh Kumar 1c4d12de27 PM / OPP: Add "opp-supported-hw" binding
We may want to enable only a subset of OPPs, from the bigger list of
OPPs, based on what version of the hardware we are running on. This
would enable us to not duplicate OPP tables for every version of the
hardware we support.

To enable that, this patch defines a new property 'opp-supported-hw'. It
can support any number of hierarchy levels of the versions the hardware
follows. And based on the selected hardware versions, we can pick only
the relevant OPPs at runtime.

Murali Karicheri 17e846aa39 ARM: dts: keystone: k2l: fix kernel crash when clk_ignore_unused is not in bootargs
Currently kernel crash randomly when K2L EVM is booted without
clk_ignore_unused in the bootargs. This workaround is not needed
on other K2 devices such as K2HK and K2E and with this fix, we can
remove the workaround altogether. netcp driver on K2L uses linked
ram on OSR (On chip Static RAM) and requires the clock to this peripheral
enabled for proper functioning. This is the reason for the kernel crash.
So add the clock node to fix this issue.

While at it, remove the workaround documentation as well.

With the fix applied, clk_summary dump shows the clock to OSR enabled.

Merge tag 'pm+acpi-4.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management and ACPI updates from Rafael Wysocki:
 "These are mostly fixes and cleanups (ACPI core, PM core, cpufreq, ACPI
  EC driver, device properties) including three reverts of recent
  intel_pstate driver commits due to a regression introduced by one of
  them plus support for Atom Airmont cores in intel_pstate (which really
  boils down to adding new frequency tables for Airmont) and additional
  turbostat updates.

  Specifics:

   - Revert three recent intel_pstate driver commits one of which
     introduced a regression and the remaining two depend on the
     problematic one (Rafael Wysocki).

   - Fix breakage related to the recently introduced ACPI _CCA object
     support in the PCI DMA setup code (Suravee Suthikulpanit).

   - Fix up the recently introduced ACPI CPPC support to only use the
     hardware-reduced version of the PCCT structure as the only
     architecture to support it (ARM64) will only use hardware-reduced
     ACPI anyway (Ashwin Chaugule).

   - Fix a cpufreq mediatek driver build problem (Arnd Bergmann).

   - Fix the SMBus transaction handling implementation in the ACPI core
     to avoid re-entrant calls to wait_event_timeout() which makes
     intermittent boot stalls related to the Smart Battery Subsystem
     initialization go away and revert a workaround of another problem
     with the same underlying root cause (Chris Bainbridge).

   - Fix the generic wakeup interrupts framework to avoid using invalid
     IRQ numbers (Dmitry Torokhov).

   - Remove a redundant check from the ACPI EC driver (Markus Elfring).

   - Modify the intel_pstate driver so it can support more Atom flavors
     than just one (Baytrail) and add support for Atom Airmont cores
     (which require new freqnency tables) to it (Philippe Longepe).

   - Clean up MSR-related symbols in turbostat (Len Brown)"

create a subdir at linux/platform_data and move the headers to that

And the references fixed with this script:
    MAIN_DIR="linux/platform_data/"
    PREV_DIR="media/"
    DIRS="media/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n

Jean-Yves Faye c7f42c6390 ipmi watchdog : add panic_wdt_timeout parameter
In order to allow panic actions to be processed, the ipmi watchdog
driver sets a new timeout value on panic. The 255s timeout
was designed to allow kdump and others actions on panic, as in
http://lkml.iu.edu/hypermail/linux/kernel/0711.3/0258.html

This is counter-intuitive for a end-user who sets watchdog timeout
value to something like 30s and who expects BMC to reset the system
within 30s of a panic.

This commit allows user to configure the timeout on panic.

Lars-Peter Clausen b36f09c3c4 dmaengine: Add transfer termination synchronization support
The DMAengine API has a long standing race condition that is inherent to
the API itself. Calling dmaengine_terminate_all() is supposed to stop and
abort any pending or active transfers that have previously been submitted.
Unfortunately it is possible that this operation races against a currently
running (or with some drivers also scheduled) completion callback.

Since the API allows dmaengine_terminate_all() to be called from atomic
context as well as from within a completion callback it is not possible to
synchronize to the execution of the completion callback from within
dmaengine_terminate_all() itself.

This means that a user of the DMAengine API does not know when it is safe
to free resources used in the completion callback, which can result in a
use-after-free race condition.

This patch addresses the issue by introducing an explicit synchronization
primitive to the DMAengine API called dmaengine_synchronize().

The existing dmaengine_terminate_all() is deprecated in favor of
dmaengine_terminate_sync() and dmaengine_terminate_async(). The former
aborts all pending and active transfers and synchronizes to the current
context, meaning it will wait until all running completion callbacks have
finished. This means it is only possible to call this function from
non-atomic context. The later function does not synchronize, but can still
be used in atomic context or from within a complete callback. It has to be
followed up by dmaengine_synchronize() before a client can free the
resources used in a completion callback.

In addition to this the semantics of the device_terminate_all() callback
are slightly relaxed by this patch. It is now OK for a driver to only
schedule the termination of the active transfer, but does not necessarily
have to wait until the DMA controller has completely stopped. The driver
must ensure though that the controller has stopped and no longer accesses
any memory when the device_synchronize() callback returns.

This was in part done since most drivers do not pay attention to this
anyway at the moment and to emphasize that this needs to be done when the
device_synchronize() callback is implemented. But it also helps with
implementing support for devices where stopping the controller can require
operations that may sleep.

Linus Torvalds d83763f4a6 SCSI misc on 20151113
Sorry for the delay in this patch which was mostly caused by getting the
 merger of the mpt2/mpt3sas driver, which was seen as an essential item of
 maintenance work to do before the drivers diverge too much.  Unfortunately,
 this caused a compile failure (detected by linux-next), which then had to be
 fixed up and incubated.  In addition to the mpt2/3sas rework, there are
 updates from pm80xx, lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc
 and ufs plus an assortment of changes including some year 2038 issues, a fix
 for a remove before detach issue in some drivers and a couple of other minor
 issues.

Linus Torvalds 9aa3d651a9 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "This series contains HCH's changes to absorb configfs attribute
  ->show() + ->store() function pointer usage from it's original
  tree-wide consumers, into common configfs code.

  It includes usb-gadget, target w/ drivers, netconsole and ocfs2
  changes to realize the improved simplicity, that now renders the
  original include/target/configfs_macros.h CPP magic for fabric drivers
  and others, unnecessary and obsolete.

  And with common code in place, new configfs attributes can be added
  easier than ever before.

  Note, there are further improvements in-flight from other folks for
  v4.5 code in configfs land, plus number of target fixes for post -rc1
  code"

In the meantime, a new user of the now-removed old configfs API came in
through the char/misc tree in commit 7bd1d4093c ("stm class: Introduce
an abstraction for System Trace Module devices").

This merge resolution comes from Alexander Shishkin, who updated his stm
class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 517982229f
("configfs: remove old API") from this pull.  As Alexander says about
that patch:

 "There's no need to keep an extra wrapper structure per item and the
  awkward show_attribute/store_attribute item ops are no longer needed.

  This patch converts policy code to the new api, all the while making
  the code quite a bit smaller and easier on the eyes.

  Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>"

That patch was folded into the merge so that the tree should be fully
bisectable.

Linus Torvalds c0d6fe2f01 ARM: DT updates for v4.4
As usual, this is the massive branch we have for each release. Lots of
 various updates and additions of hardware descriptions on existing hardware,
 as well as the usual additions of new boards and SoCs.
 
 This is also the first release where we've started mixing 64- and 32-bit
 DT updates in one branch.
 
 (Specific details on what's actually here and new is pretty easy to tell
 from the diffstat, so there's little point in duplicating listing it here.)

Linus Torvalds b44a3d2a85 ARM: SoC driver updates for v4.4
As we've enabled multiplatform kernels on ARM, and greatly done away with
 the contents under arch/arm/mach-*, there's still need for SoC-related
 drivers to go somewhere.
 
 Many of them go in through other driver trees, but we still have
 drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
 that might be shared between ARM and ARM64 (or just in general makes
 sense to not have under the architecture directory).
 
 This branch contains mostly such code:
 
 - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate
   with power management blocks on these SoCs for use by clock, regulator and
   bus frequency drivers.
 - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs.
 - Drivers for ARM's SCPI (System Control Processor). Not to be confused with
   PSCI (Power State Coordination Interface). SCPI is used to communicate with
   the assistant embedded cores doing power management, and we have yet to see
   how many of them will implement this for their hardware vs abstracting in
   other ways (or not at all like in the past).
 - To make confusion between SCPI and PSCI more likely, this release also
   includes an update of PSCI to interface version 1.0.
 - Rockchip support for power domains.
 - A driver to talk to the firmware on Raspberry Pi.

 Main contents here is:

  - Removal of bockw platforms on shmobile, since the platform has now gone
    completely multiplatform. Whee!
  - move of the 32kHz timer on OMAP to a proper timesource
  - Misc cleanup of older OMAP material (incl removal of one board file)
  - Switch over to new common PWM lookup support for several platforms
 
 There's also a handful of other cleanups across the tree, but the above are
 the major pieces.

Linus Torvalds 264015f8a8 libnvdimm for 4.4:
1/ Add support for the ACPI 6.0 NFIT hot add mechanism to process
    updates of the NFIT at runtime.
 
 2/ Teach the coredump implementation how to filter out DAX mappings.
 
 3/ Introduce NUMA hints for allocations made by the pmem driver, and as
    a side effect all devm allocations now hint their NUMA node by
    default.

Merge tag 'libnvdimm-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "Outside of the new ACPI-NFIT hot-add support this pull request is more
  notable for what it does not contain, than what it does.  There were a
  handful of development topics this cycle, dax get_user_pages, dax
  fsync, and raw block dax, that need more more iteration and will wait
  for 4.5.

  The patches to make devm and the pmem driver NUMA aware have been in
  -next for several weeks.  The hot-add support has not, but is
  contained to the NFIT driver and is passing unit tests.  The coredump
  support is straightforward and was looked over by Jeff.  All of it has
  received a 0day build success notification across 107 configs.

  Summary:

   - Add support for the ACPI 6.0 NFIT hot add mechanism to process
     updates of the NFIT at runtime.

   - Teach the coredump implementation how to filter out DAX mappings.

   - Introduce NUMA hints for allocations made by the pmem driver, and
     as a side effect all devm allocations now hint their NUMA node by
     default"

The PWM controller on sun5i SoCs is identical to the one found on sun7i
SoCs. On the A13 package only one of the 2 pins is routed to the outside,
so only advertise one PWM channel there.

Linus Torvalds 9d74288ca7 GFS2: merge window
Here is a list of patches we've accumulated for GFS2 for the current upstream
 merge window. There are only six patches this time:
 
 1. A cleanup patch from Andreas to remove the gl_spin #define in favor
    of its value for the sake of clarity.
 2. A fix from Andy Price to mark the inode dirty during fallocate.
 3. A fix from Andy Price to set s_mode on mount failures to prevent
    a stack trace.
 4. A patch from me to prevent a kernel BUG() in trans_add_meta/trans_add_data
    due to uninitialized storage.
 5. A patch from me to protecting our freeing of the in-core directory
    hash table to prevent double-free.
 6. A fix for a page/block rounding problem that resulted in a metadata
    coherency problem when the block size != page size.
 
 I've got a lot more patches in various stages of review and testing,
 but I'm afraid they'll have to wait until the next merge window. So
 next time we're likely to have a lot more.

Seymour, Shane M d9b43a10f0 st: allow debug output to be enabled or disabled via sysfs
Change st driver to allow enabling or disabling debug output
via sysfs file /sys/bus/scsi/drivers/st/debug_flag.

Previously the only way to enable debug output was:

1. loading the driver with the module parameter debug_flag=1
2. an ioctl call (this method was also the only way to dynamically
disable debug output).

To use the ioctl you need a second tape drive (if you are
actively testing the first tape drive) since a second process
cannot open the first tape drive if it is in use.

The this change is only functional if the value of the macro
DEBUG in st.c is a non-zero value (which it is by default).

Yaniv Gardi 47555a5c8a scsi: ufs: make the UFS variant a platform device
This change turns the UFS variant (SCSI_UFS_QCOM) into a UFS
a platform device.
In order to do so a few additional changes are required:
1. The ufshcd-pltfrm is no longer serves as a platform device.
   Now it only serves as a group of platform APIs such as PM APIs
   (runtime suspend/resume, system suspend/resume etc), parsers of
   clocks, regulators and pm_levels from DT.
2. What used to be the old platform "probe" is now "only"
   a pltfrm_init() routine, that does exactly the same, but only
   being called by the new probe function of the UFS variant.

Ross Zwisler 5037835c1f coredump: add DAX filtering for ELF coredumps
Add two new flags to the existing coredump mechanism for ELF files to
allow us to explicitly filter DAX mappings.  This is desirable because
DAX mappings, like hugetlb mappings, have the potential to be very
large.

Update the coredump_filter documentation in
Documentation/filesystems/proc.txt so that it addresses the new DAX
coredump flags.  Also update the documented default value of
coredump_filter to be consistent with the core(5) man page.  The
documentation being updated talks about bit 4, Dump ELF headers, which
is enabled if CONFIG_CORE_DUMP_DEFAULT_ELF_HEADERS is turned on in the
kernel config.  This kernel config option defaults to "y" if both ELF
binaries and coredump are enabled.

Kirill A. Shutemov 1d798ca3f1 mm: make compound_head() robust
Hugh has pointed that compound_head() call can be unsafe in some
context. There's one example:

	CPU0					CPU1

isolate_migratepages_block()
  page_count()
    compound_head()
      !!PageTail() == true
					put_page()
					  tail->first_page = NULL
      head = tail->first_page
					alloc_pages(__GFP_COMP)
					   prep_compound_page()
					     tail->first_page = head
					     __SetPageTail(p);
      !!PageTail() == true
    <head == NULL dereferencing>

The race is pure theoretical. I don't it's possible to trigger it in
practice. But who knows.

We can fix the race by changing how encode PageTail() and compound_head()
within struct page to be able to update them in one shot.

The patch introduces page->compound_head into third double word block in
front of compound_dtor and compound_order. Bit 0 encodes PageTail() and
the rest bits are pointer to head page if bit zero is set.

The patch moves page->pmd_huge_pte out of word, just in case if an
architecture defines pgtable_t into something what can have the bit 0
set.

hugetlb_cgroup uses page->lru.next in the second tail page to store
pointer struct hugetlb_cgroup. The patch switch it to use page->private
in the second tail page instead. The space is free since ->first_page is
removed from the union.

The patch also opens possibility to remove HUGETLB_CGROUP_MIN_ORDER
limitation, since there's now space in first tail page to store struct
hugetlb_cgroup pointer. But that's out of scope of the patch.

That means page->compound_head shares storage space with:

 - page->lru.next;
 - page->next;
 - page->rcu_head.next;

That's too long list to be absolutely sure, but looks like nobody uses
bit 0 of the word.

page->rcu_head.next guaranteed[1] to have bit 0 clean as long as we use
call_rcu(), call_rcu_bh(), call_rcu_sched(), or call_srcu(). But future
call_rcu_lazy() is not allowed as it makes use of the bit and we can
get false positive PageTail().

Mel Gorman d0164adc89 mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd
__GFP_WAIT has been used to identify atomic context in callers that hold
spinlocks or are in interrupts.  They are expected to be high priority and
have access one of two watermarks lower than "min" which can be referred
to as the "atomic reserve".  __GFP_HIGH users get access to the first
lower watermark and can be called the "high priority reserve".

Over time, callers had a requirement to not block when fallback options
were available.  Some have abused __GFP_WAIT leading to a situation where
an optimisitic allocation with a fallback option can access atomic
reserves.

This patch uses __GFP_ATOMIC to identify callers that are truely atomic,
cannot sleep and have no alternative.  High priority users continue to use
__GFP_HIGH.  __GFP_DIRECT_RECLAIM identifies callers that can sleep and
are willing to enter direct reclaim.  __GFP_KSWAPD_RECLAIM to identify
callers that want to wake kswapd for background reclaim.  __GFP_WAIT is
redefined as a caller that is willing to enter direct reclaim and wake
kswapd for background reclaim.

This patch then converts a number of sites

o __GFP_ATOMIC is used by callers that are high priority and have memory
  pools for those requests. GFP_ATOMIC uses this flag.

o Callers that have a limited mempool to guarantee forward progress clear
  __GFP_DIRECT_RECLAIM but keep __GFP_KSWAPD_RECLAIM. bio allocations fall
  into this category where kswapd will still be woken but atomic reserves
  are not used as there is a one-entry mempool to guarantee progress.

o Callers that are checking if they are non-blocking should use the
  helper gfpflags_allow_blocking() where possible. This is because
  checking for __GFP_WAIT as was done historically now can trigger false
  positives. Some exceptions like dm-crypt.c exist where the code intent
  is clearer if __GFP_DIRECT_RECLAIM is used instead of the helper due to
  flag manipulations.

o Callers that built their own GFP flags instead of starting with GFP_KERNEL
  and friends now also need to specify __GFP_KSWAPD_RECLAIM.

The first key hazard to watch out for is callers that removed __GFP_WAIT
and was depending on access to atomic reserves for inconspicuous reasons.
In some cases it may be appropriate for them to use __GFP_HIGH.

The second key hazard is callers that assembled their own combination of
GFP flags instead of starting with something like GFP_KERNEL.  They may
now wish to specify __GFP_KSWAPD_RECLAIM.  It's almost certainly harmless
if it's missed in most cases as other activity will wake kswapd.

Linus Torvalds 22402cd0af Most of the changes are clean ups and small fixes. Some of them have
stable tags to them. I searched through my INBOX just as the merge window
 opened and found lots of patches to pull. I ran them through all my tests
 and they were in linux-next for a few days.
 
 Features added this release:
 ----------------------------
 
  o Module globbing. You can now filter function tracing to several
    modules. # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov)
 
  o Tracer specific options are now visible even when the tracer is not
    active. It was rather annoying that you can only see and modify tracer
    options after enabling the tracer. Now they are in the options/ directory
    even when the tracer is not active. Although they are still only visible
    when the tracer is active in the trace_options file.
 
  o Trace options are now per instance (although some of the tracer specific
    options are global)
 
  o New tracefs file: set_event_pid. If any pid is added to this file, then
    all events in the instance will filter out events that are not part of
    this pid. sched_switch and sched_wakeup events handle next and the wakee
    pids.

Merge tag 'trace-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracking updates from Steven Rostedt:
 "Most of the changes are clean ups and small fixes.  Some of them have
  stable tags to them.  I searched through my INBOX just as the merge
  window opened and found lots of patches to pull.  I ran them through
  all my tests and they were in linux-next for a few days.

  Features added this release:
  ----------------------------

   - Module globbing.  You can now filter function tracing to several
     modules.  # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov)

   - Tracer specific options are now visible even when the tracer is not
     active.  It was rather annoying that you can only see and modify
     tracer options after enabling the tracer.  Now they are in the
     options/ directory even when the tracer is not active.  Although
     they are still only visible when the tracer is active in the
     trace_options file.

   - Trace options are now per instance (although some of the tracer
     specific options are global)

   - New tracefs file: set_event_pid.  If any pid is added to this file,
     then all events in the instance will filter out events that are not
     part of this pid.  sched_switch and sched_wakeup events handle next
     and the wakee pids"

Linus Torvalds 9bbd4b9f38 DeviceTree updates for 4.4:
- DT binding doc consolidation moving similar bindings to common
   locations. The majority of these are display related which were
   scattered in video/, fb/, drm/, gpu/, and panel/ directories.
 - Add new config option, CONFIG_OF_ALL_DTBS, to enable building all dtbs
   in the tree for most arches with dts files (except powerpc for now).
 - OF_IRQ=n fixes for user enabled CONFIG_OF.
 - of_node_put ref counting fixes from Julia Lawall.
 - Common DT binding for wakeup-source and deprecation of all similar
   bindings.
 - DT binding for PXA LCD controller.
 - Allow ignoring failed PCI resource translations in order to ignore
   64-bit addresses on non-LPAE 32-bit kernels.
 - Support setting the NUMA node from DT instead of only from parent
   device.
 - Couple of earlycon DT parsing fixes for address and options.

Pull input updates from Dmitry Torokhov:
 "Items of note:

   - evdev users can now limit or mask the kind of events they will
     receive.  This will allow applications such as power manager or
     network manager to only be woken when user presses special keys
     such as KEY_POWER or KEY_WIFI and not be bothered with ordinary
     key presses coming from keyboard

   - support for FocalTech FT6236 touchscreen controller

   - support for ROHM BU21023/24 touchscreen controller

   - edt-ft5x06 touchscreen driver got a face lift and can now be used
