Pull watchddog clean-up and fixes from Thomas Gleixner:
 "The watchdog (hard/softlockup detector) code is pretty much broken in
  its current state. The patch series addresses this by removing all
  duct tape and refactoring it into a workable state.

  The reasons why I ask for inclusion that late in the cycle are:

   1) The code causes lockdep splats vs. hotplug locking which get
      reported over and over. Unfortunately there is no easy fix.

   2) The risk of breakage is minimal because it's already broken

   3) As 4.14 is a long term stable kernel, I prefer to have working
      watchdog code in that and the lockdep issues resolved. I wouldn't
      ask you to pull if 4.14 wouldn't be a LTS kernel or if the
      solution would be easy to backport.

   4) The series was around before the merge window opened, but then got
      delayed due to the UP failure caused by the for_each_cpu()
      surprise which we discussed recently.

  Changes vs. V1:

   - Addressed your review points

   - Addressed the warning in the powerpc code which was discovered late

   - Changed two function names which made sense up to a certain point
     in the series. Now they match what they do in the end.

   - Fixed a 'unused variable' warning, which got not detected by the
     intel robot. I triggered it when trying all possible related config
     combinations manually. Randconfig testing seems not random enough.

  The changes have been tested by and reviewed by Don Zickus and tested
  and acked by Micheal Ellerman for powerpc"

  dm raid: fix incorrect status output at the end of a "recover" process
  dm crypt: reject sector_size feature if device length is not aligned to it
  dm crypt: fix memory leak in crypt_ctr_cipher_old()
  dm ioctl: fix alignment of event number in the device list

There are three important fields that indicate the overall health and
status of an array: dev_health, sync_ratio, and sync_action.  They tell
us the condition of the devices in the array, and the degree to which
the array is synchronized.

This commit fixes a condition that is reported incorrectly.  When a member
of the array is being rebuilt or a new device is added, the "recover"
process is used to synchronize it with the rest of the array.  When the
process is complete, but the sync thread hasn't yet been reaped, it is
possible for the state of MD to be:
 mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
 curr_resync_completed = <max dev size> (but not MaxSector)
 and all rdevs to be In_sync.
This causes the 'array_in_sync' output parameter that is passed to
rs_get_progress() to be computed incorrectly and reported as 'false' --
or not in-sync.  This in turn causes the dev_health status characters to
be reported as all 'a', rather than the proper 'A'.

This can cause erroneous output for several seconds at a time when tools
will want to be checking the condition due to events that are raised at
the end of a sync process.  Fix this by properly calculating the
'array_in_sync' return parameter in rs_get_progress().

Also, remove an unnecessary intermediate 'recovery_cp' variable in
rs_get_progress().

Pull ARM SoC fixes from Olof Johansson:
 "Our first batch of fixes this release cycle, unfortunately a bit
  noisier than usual. Two major groups stand out:

   - Some pinctril dts/dtsi changes for stm32 due to a new driver being
     merged during the merge window, and this aligns the DT contents
     between the old format and the new. This could arguably be moved to
     the next merge window but it also seemed relatively harmless to
     include now.

   - Amlogic/meson had driver changes merged that required devicetree
     changes to avoid functional/performance regressions. I've already
     asked them to be more careful about this going forward, and making
     sure drivers are compatible with older DTs when they make these
     kind of changes. The platform is actively being upstreamed so
     there's a few things in flight, we've seen this happen before and
     sometimes it's hard to catch in time.

The rework of the core hotplug code triggers the WARN_ON in start_wd_cpu()
on powerpc because it is called multiple times for the boot CPU.

The first call is via:

  start_wd_on_cpu+0x80/0x2f0
  watchdog_nmi_reconfigure+0x124/0x170
  softlockup_reconfigure_threads+0x110/0x130
  lockup_detector_init+0xbc/0xe0
  kernel_init_freeable+0x18c/0x37c
  kernel_init+0x2c/0x160
  ret_from_kernel_thread+0x5c/0xbc

And then again via the CPU hotplug registration:

  start_wd_on_cpu+0x80/0x2f0
  cpuhp_invoke_callback+0x194/0x620
  cpuhp_thread_fun+0x7c/0x1b0
  smpboot_thread_fn+0x290/0x2a0
  kthread+0x168/0x1b0
  ret_from_kernel_thread+0x5c/0xbc

This can be avoided by setting up the cpu hotplug state with nocalls and
move the initialization to the watchdog_nmi_probe() function. That
initializes the hotplug callbacks without invoking the callback and the
following core initialization function then configures the watchdog for the
online CPUs (in this case CPU0) via softlockup_reconfigure_threads().

The recent cleanup of the watchdog code split watchdog_nmi_reconfigure()
into two stages. One to stop the NMI and one to restart it after
reconfiguration. That was done by adding a boolean 'run' argument to the
code, which is functionally correct but not necessarily a piece of art.

Replace it by two explicit functions: watchdog_nmi_stop() and
watchdog_nmi_start().

security_inode_getsecurity() provides the text string value
of a security attribute. It does not provide a "secctx".
The code in xattr_getsecurity() that calls security_inode_getsecurity()
and then calls security_release_secctx() happened to work because
SElinux and Smack treat the attribute and the secctx the same way.
It fails for cap_inode_getsecurity(), because that module has no
secctx that ever needs releasing. It turns out that Smack is the
one that's doing things wrong by not allocating memory when instructed
to do so by the "alloc" parameter.

The fix is simple enough. Change the security_release_secctx() to
kfree() because it isn't a secctx being returned by
security_inode_getsecurity(). Change Smack to allocate the string when
told to do so.

Note: this also fixes memory leaks for LSMs which implement
inode_getsecurity but not release_secctx, such as capabilities.

Merge tag 'v4.14-rockchip-dts64fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into fixes

Adding the operating points on rk3368 like they were did not end up well
for the boards as all of them are missing their cpu supplies, the OPPs
actually need to follow the <target min max> format as the regulator is
shared between both clusters and the one rk3368 board I have, somehow also
doesn't like the higher opps at all - all of which I only realized after
I brought my rk3368 board online again, after its bootloader broke.
So we revert that OPP addition for now.

And also two fixes for the mipi dsi controller on rk3399, which was
referencing a clock to high up in the clock-tree so that an intermediate
gate could be disabled inadvertently and also needs a clock for its area
in the general register files of the rk3399 soc.

Before commit 9c5d760b ("mm: split gfp_mask and mapping flags into
separate fields") the private_* fields of struct adrress_space were
grouped together and using "ditto" in comments describing the last
fields was correct.

With introduction of gpf_mask between private_lock and private_list
"ditto" references the wrong description.

Fix it by using the elaborate description.

printk_ratelimit() invokes ___ratelimit() which may invoke a normal
printk() (pr_warn() in this particular case) to warn about suppressed
output.  Given that printk_ratelimit() may be called from anywhere, that
pr_warn() is dangerous - it may end up deadlocking the system.  Fix
___ratelimit() by using deferred printk().

Function param_attr_show could overflow the buffer it is operating on.

The buffer size is PAGE_SIZE, and the string returned by
attribute->param->ops->get is generated by scnprintf(buffer, PAGE_SIZE,
...) so it could be PAGE_SIZE - 1 long, with the terminating '\0' at the
very end of the buffer.  Calling strcat(..., "\n") on this isn't safe, as
the '\0' will be replaced by '\n' (OK) and then another '\0' will be added
past the end of the buffer (not OK.)

Simply add the trailing '\n' when writing the attribute contents to the
buffer originally.  This is safe, and also faster.

The length parameter of strlcpy() is supposed to reflect the size of the
target buffer, not of the source string.  Harmless in this case as the
buffer is PAGE_SIZE long and the source string is always much shorter than
this, but conceptually wrong, so let's fix it.
