Greta Zhang 5724485b18 watchdog: mtk_wdt: add wdt shutdown callback to disable wdt if enabled
Without .shutdown(), watchdog might reset the system during power off.
For example, if watchdog's timeout is set to 30s, then it is reset to
zero by mtk_wdt_ping(). During power off, no app will ping watchdog,
but watchdog is still running and may trigger reset.

Timur Tabi f15d7114bb Documentation/watchdog: add timeout and ping rate control to watchdog-test.c
The watchdog test program is much more useful if it can configure the
timeout value and ping rate.  This will allow you to test actual timeouts.

Adds the -t parameter to set the timeout value (in seconds), and -p to set
the ping rate (number of seconds between pings).

Linus Torvalds b8889c4fc6 TTY driver revert for 4.3-rc1
Here are some reverts for some tty patches (specifically the pl011
 driver) that ended up breaking a bunch of machines (i.e. almost all of
 the ones with this chip.)  People are working on a fix for this, but in
 the meantime, it's best to just revert all 5 patches to restore people's
 serial consoles.
 
 These reverts have been in linux-next for many days now.

This set of changes introduces the beginnings of a new API that's based
 around the concept of states that can be atomically applied. Drivers go
 to various lengths to implement something similar, which indicates that
 the core should really be providing the necessary framework.
 
 On top of that, there is a bit of cleanup as well as improved kerneldoc

Ross Zwisler d77e92e270 dax: update PMD fault handler with PMEM API
As part of the v4.3 merge window the DAX code was updated by Matthew and
Kirill to handle PMD pages.  Also as part of the v4.3 merge window we
updated the DAX code to do proper PMEM flushing (commit 2765cfbb342c:
"dax: update I/O path to do proper PMEM flushing").

The additional code added by the DAX PMD patches also needs to be
updated to properly use the PMEM API.  This ensures that after a PMD
fault is handled the zeros written to the newly allocated pages are
durable on the DIMMs.

linux/dax.h is included to get rid of a bunch of sparse warnings.

Pull inifiniband/rdma updates from Doug Ledford:
 "This is a fairly sizeable set of changes.  I've put them through a
  decent amount of testing prior to sending the pull request due to
  that.

  There are still a few fixups that I know are coming, but I wanted to
  go ahead and get the big, sizable chunk into your hands sooner rather
  than waiting for those last few fixups.

  Of note is the fact that this creates what is intended to be a
  temporary area in the drivers/staging tree specifically for some
  cleanups and additions that are coming for the RDMA stack.  We
  deprecated two drivers (ipath and amso1100) and are waiting to hear
  back if we can deprecate another one (ehca).  We also put Intel's new
  hfi1 driver into this area because it needs to be refactored and a
  transfer library created out of the factored out code, and then it and
  the qib driver and the soft-roce driver should all be modified to use
  that library.

  I expect drivers/staging/rdma to be around for three or four kernel
  releases and then to go away as all of the work is completed and final
  deletions of deprecated drivers are done.

  Summary of changes for 4.3:

   - Create drivers/staging/rdma
   - Move amso1100 driver to staging/rdma and schedule for deletion
   - Move ipath driver to staging/rdma and schedule for deletion
   - Add hfi1 driver to staging/rdma and set TODO for move to regular
     tree
   - Initial support for namespaces to be used on RDMA devices
   - Add RoCE GID table handling to the RDMA core caching code
   - Infrastructure to support handling of devices with differing read
     and write scatter gather capabilities
   - Various iSER updates
   - Kill off unsafe usage of global mr registrations
   - Update SRP driver
   - Misc  mlx4 driver updates
   - Support for the mr_alloc verb
   - Support for a netlink interface between kernel and user space cache
     daemon to speed path record queries and route resolution
   - Ininitial support for safe hot removal of verbs devices"

Ariel D'Alessandro 841e6f90bb pwm: NXP LPC18xx PWM/SCT driver
This commit adds support for NXP LPC18xx PWM/SCT.

NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State
Configurable Timer (SCT) which can be configured as a Pulse Width
Modulator. Other SoCs in that family may share the same hardware.

The PWM supports a total of 16 channels, but only 15 can be simultaneously
requested. There's only one period, global to all the channels, thus PWM
driver will refuse setting different values to it, unless there's only one
channel requested.

Chris Wilson acd29f7b22 drm/i915: Limit the number of loops for reading a split 64bit register
In I915_READ64_2x32 we attempt to read a 64bit register using 2 32bit
reads. Due to the nature of the registers we try to read in this manner,
they may increment between the two instruction (e.g. a timestamp
counter). To keep the result accurate, we repeat the read if we detect
an overflow (i.e. the upper value varies). However, some hardware is just
plain flaky and may endless loop as the the upper 32bits are not stable.
Just give up after a couple of tries and report whatever we read last.

v2: Use the most recent values when erring out on an unstable register.

When readahead encounters file holes, osd reply returns error -ENOENT,
finish_read() skips adding pages to the the page cache. So readahead
does not work for file holes. The fix is adding zero pages to the

Ilya Dryomov d15f9d694b libceph: check data_len in ->alloc_msg()
Only ->alloc_msg() should check data_len of the incoming message
against the preallocated ceph_msg, doing it in the messenger is not
right.  The contract is that either ->alloc_msg() returns a ceph_msg
which will fit all of the portions of the incoming message, or it
returns NULL and possibly sets skip, signaling whether NULL is due to
an -ENOMEM.  ->alloc_msg() should be the only place where we make the
skip/no-skip decision.

I stumbled upon this while looking at con/osd ref counting.  Right now,
if we get a non-extent message with a larger data portion than we are
prepared for, ->alloc_msg() returns a ceph_msg, and then, when we skip
it in the messenger, we don't put the con/osd ref acquired in
ceph_con_in_msg_alloc() (which is normally put in process_message()),
so this also fixes a memory leak.

An existing BUG_ON in ceph_msg_data_cursor_init() ensures we don't
corrupt random memory should a buggy ->alloc_msg() return an unfit
ceph_msg.

While at it, I changed the "unknown tid" dout() to a pr_warn() to make
sure all skips are seen and unified format strings.

If an attempt to wake up users of broadcast link is made when there is
no enough place in send queue than it may hang up inside the
tipc_sk_rcv() function since the loop breaks only after the wake up
queue becomes empty. This can lead to complete CPU stall with the
following message generated by RCU:

 <EOI>

The issue occurs only when tipc_sk_rcv() is used to wake up postponed
senders:

	tipc_bclink_wakeup_users()
		// wakeupq - is a queue which consists of special
		// 		 messages with SOCK_WAKEUP type.
		tipc_sk_rcv(wakeupq)
			...
			while (skb_queue_len(inputq)) {
				filter_rcv(skb)
					// Here the type of message is checked
					// and if it is SOCK_WAKEUP then
					// it tries to wake up a sender.
					tipc_write_space(sk)
						wake_up_interruptible_sync_poll()
			}

After the sender thread is woke up it can gather control and perform
an attempt to send a message. But if there is no enough place in send
queue it will call link_schedule_user() function which puts a message
of type SOCK_WAKEUP to the wakeup queue and put the sender to sleep.
Thus the size of the queue actually is not changed and the while()
loop never exits.

The approach I proposed is to wake up only senders for which there is
enough place in send queue so the described issue can't occur.
Moreover the same approach is already used to wake up senders on
unicast links.

I have got into the issue on our product code but to reproduce the
issue I changed a benchmark test application (from
tipcutils/demos/benchmark) to perform the following scenario:
	1. Run 64 instances of test application (nodes). It can be done
	   on the one physical machine.
	2. Each application connects to all other using TIPC sockets in
	   RDM mode.
	3. When setup is done all nodes start simultaneously send
	   broadcast messages.
	4. Everything hangs up.

The issue is reproducible only when a congestion on broadcast link
occurs. For example, when there are only 8 nodes it works fine since
congestion doesn't occur. Send queue limit is 40 in my case (I use a
critical importance level) and when 64 nodes send a message at the
same moment a congestion occurs every time.

Florian Fainelli 39797a279d net: dsa: bcm_sf2: Fix ageing conditions and operation
The comparison check between cur_hw_state and hw_state is currently
invalid because cur_hw_state is right shifted by G_MISTP_SHIFT, while
hw_state is not, so we end-up comparing bits 2:0 with bits 7:5, which is
going to cause an additional aging to occur. Fix this by not shifting
cur_hw_state while reading it, but instead, mask the value with the
appropriately shitfted bitmask.

The other problem with the fast-ageing process is that we did not set
the EN_AGE_DYNAMIC bit to request the ageing to occur for dynamically
learned MAC addresses. Finally, write back 0 to the FAST_AGE_CTRL
register to avoid leaving spurious bits sets from one operation to the
other.

Linus Torvalds 9a9952bbd7 IOMMU Updates for Linux v4.3
This time the IOMMU updates are mostly cleanups or fixes. No big new
 features or drivers this time. In particular the changes include:
 
 	* Bigger cleanup of the Domain<->IOMMU data structures and the
 	  code that manages them in the Intel VT-d driver. This makes
 	  the code easier to understand and maintain, and also easier to
 	  keep the data structures in sync. It is also a preparation
 	  step to make use of default domains from the IOMMU core in the
 	  Intel VT-d driver.
 
 	* Fixes for a couple of DMA-API misuses in ARM IOMMU drivers,
 	  namely in the ARM and Tegra SMMU drivers.
 
 	* Fix for a potential buffer overflow in the OMAP iommu driver's
 	  debug code
 
 	* A couple of smaller fixes and cleanups in various drivers
 
 	* One small new feature: Report domain-id usage in the Intel
 	  VT-d driver to easier detect bugs where these are leaked.

Linus Torvalds e81b594cda regmap: Changes for v4.3
This has been a busy release for regmap.  By far the biggest set of
 changes here are those from Markus Pargmann which implement support for
 block transfers in smbus devices.  This required quite a bit of
 refactoring but leaves us better able to handle odd restrictions that
 controllers may have and with better performance on smbus.
 
 Other new features include:
 
  - Fix interactions with lockdep for nested regmaps (eg, when a device
    using regmap is connected to a bus where the bus controller has a
    separate regmap).  Lockdep's default class identification is too
    crude to work without help.
  - Support for must write bitfield operations, useful for operations
    which require writing a bit to trigger them from Kuniori Morimoto.
  - Support for delaying during register patch application from Nariman
    Poushin.
  - Support for overriding cache state via the debugfs implementation
    from Richard Fitzgerald.

Viresh Kumar d70e22d5bc hexagon/time: Migrate to new 'set-state' interface
Migrate hexagon driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.

This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.

We weren't doing anything in the ->set_mode() callback. So, this patch
doesn't provide any set-state callbacks.

Linus Torvalds acceba598e Merge branch 'i2c/for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
 "Features:

   - new drivers: Renesas EMEV2, register based MUX, NXP LPC2xxx
   - core: scans DT and assigns wakeup interrupts.  no driver changes needed.
   - core: some refcouting issues fixed and better API for that
   - core: new helper function for best effort block read emulation
   - slave framework: proper DT bindings and userspace instantiation
   - some bigger work for xiic, pxa, omap drivers

  .. and quite a number of smaller driver fixes, cleanups, improvements"
