d5318d302e backlight: as3711_bl: Fix Device Tree node leaks
Two framebuffer device-node names were looked up during probe, but were
only used as flags to indicate the presence of two framebuffer device.

Drop the unused framebuffer name along with a likewise unused device
pointer from the driver data, and update the platform data to pass in
booleans instead of the framebuffer strings. This allows us do drop the
node references acquired during probe, which would otherwise leak.

Note that there are no other in-kernel users of the modified
platform-data fields.

2b12dfa124 backlight: tps65217_bl: Fix Device Tree node lookup
Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.

This would only cause trouble if the child node is missing while there
is an unrelated node named "backlight" elsewhere in the tree.

1658dcee3d gcc-plugins: allow to enable GCC_PLUGINS for COMPILE_TEST
Now that the compiler's plugin support is checked in Kconfig,
all{yes,mod}config will not be bothered.

Remove 'depends on !COMPILE_TEST' for GCC_PLUGINS.

'depends on !COMPILE_TEST' for the following three are still kept:
  GCC_PLUGIN_CYC_COMPLEXITY
  GCC_PLUGIN_STRUCTLEAK_VERBOSE
  GCC_PLUGIN_RANDSTRUCT_PERFORMANCE

Kees suggested to do so because the first two are too noisy, and the
last one would reduce the compile test coverage.  I commented the
reasons in arch/Kconfig.

59f53855ba gcc-plugins: test plugin support in Kconfig and clean up Makefile
Run scripts/gcc-plugin.sh from Kconfig so that users can enable
GCC_PLUGINS only when the compiler supports building plugins.

Kconfig defines a new symbol, PLUGIN_HOSTCC.  This will contain
the compiler (g++ or gcc) used for building plugins, or empty
if the plugin can not be supported at all.

This allows us to remove all ugly testing in Makefile.gcc-plugins.

5aadfdeb8d kcov: test compiler capability in Kconfig and correct dependency
As Documentation/kbuild/kconfig-language.txt notes, 'select' should be
be used with care - it forces a lower limit of another symbol, ignoring
the dependency.  Currently, KCOV can select GCC_PLUGINS even if arch
does not select HAVE_GCC_PLUGINS.  This could cause the unmet direct
dependency.

Now that Kconfig can test compiler capability, let's handle this in a
more sophisticated way.

There are two ways to enable KCOV; use the compiler that natively
supports -fsanitize-coverage=trace-pc, or build the SANCOV plugin if
the compiler has ability to build GCC plugins.  Hence, the correct
dependency for KCOV is:

  depends on CC_HAS_SANCOV_TRACE_PC || GCC_PLUGINS

You do not need to build the SANCOV plugin if the compiler already
supports -fsanitize-coverage=trace-pc.  Hence, the select should be:

  select GCC_PLUGIN_SANCOV if !CC_HAS_SANCOV_TRACE_PC

With this, GCC_PLUGIN_SANCOV is selected only when necessary, so
scripts/Makefile.gcc-plugins can be cleaner.

I also cleaned up Kconfig and scripts/Makefile.kcov as well.

5f85942c2e SCSI misc on 20180610
This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
 xfcp, hisi_sas, cxlflash, qla2xxx.  In the absence of Nic, we're also
 taking target updates which are mostly minor except for the tcmu
 refactor. The only real core change to worry about is the removal of
 high page bouncing (in sas, storvsc and iscsi).  This has been well
 tested and no problems have shown up so far.

b718e8c8f4 net: phy: dp83822: use BMCR_ANENABLE instead of BMSR_ANEGCAPABLE for DP83620
DP83620 register set is compatible with the DP83848, but it also supports
100base-FX. When the hardware is configured such as that fiber mode is
enabled, autonegotiation is not possible.

The chip, however, doesn't expose this information via BMSR_ANEGCAPABLE.
Instead, this bit is always set high, even if the particular hardware
configuration makes it so that auto negotiation is not possible [1]. Under
these circumstances, the phy subsystem keeps trying for autonegotiation to
happen, without success.

Hereby, we inspect BMCR_ANENABLE bit after genphy_config_init, which on
reset is set to 0 when auto negotiation is disabled, and so we use this
value instead of BMSR_ANEGCAPABLE.

6d8c50dcb0 socket: close race condition between sock_close() and sockfs_setattr()
fchownat() doesn't even hold refcnt of fd until it figures out
fd is really needed (otherwise is ignored) and releases it after
it resolves the path. This means sock_close() could race with
sockfs_setattr(), which leads to a NULL pointer dereference
since typically we set sock->sk to NULL in ->release().

As pointed out by Al, this is unique to sockfs. So we can fix this
in socket layer by acquiring inode_lock in sock_close() and
checking against NULL in sockfs_setattr().

sock_release() is called in many places, only the sock_close()
path matters here. And fortunately, this should not affect normal
sock_close() as it is only called when the last fd refcnt is gone.
It only affects sock_close() with a parallel sockfs_setattr() in
progress, which is not common.

Fixes: 86741ec254 ("net: core: Add a UID field to struct sock.")

Pull x86 updates and fixes from Thomas Gleixner:

 - Fix the (late) fallout from the vector management rework causing
   hlist corruption and irq descriptor reference leaks caused by a
   missing sanity check.

   The straight forward fix triggered another long standing issue to
   surface. The pre rework code hid the issue due to being way slower,
   but now the chance that user space sees an EBUSY error return when
   updating irq affinities is way higher, though quite a bunch of
   userspace tools do not handle it properly despite the fact that EBUSY
   could be returned for at least 10 years.

   It turned out that the EBUSY return can be avoided completely by
   utilizing the existing delayed affinity update mechanism for irq
   remapped scenarios as well. That's a bit more error handling in the
   kernel, but avoids fruitless fingerpointing discussions with tool
   developers.

 - Decouple PHYSICAL_MASK from AMD SME as its going to be required for
   the upcoming Intel memory encryption support as well.

 - Handle legacy device ACPI detection properly for newer platforms

 - Fix the wrong argument ordering in the vector allocation tracepoint

 - Simplify the IDT setup code for the APIC=n case

 - Use the proper string helpers in the MTRR code

 - Remove a stale unused VDSO source file

59dc6f3c6d signal: Remove no longer required irqsave/restore
Commit a841796f11 ("signal: align __lock_task_sighand() irq disabling and
RCU") introduced a rcu read side critical section with interrupts
disabled. The changelog suggested that a better long-term fix would be "to
make rt_mutex_unlock() disable irqs when acquiring the rt_mutex structure's
->wait_lock".

This long-term fix has been made in commit b4abf91047 ("rtmutex: Make
wait_lock irq safe") for a different reason.

Therefore revert commit a841796f11 ("signal: align >
__lock_task_sighand() irq disabling and RCU") as the interrupt disable
dance is not longer required.

The change was tested on the base of b4abf91047 ("rtmutex: Make wait_lock
irq safe") with a four hour run of rcutorture scenario TREE03 with lockdep
enabled as suggested by Paul McKenney.

else entirely, but the traditional model is to just edit things in place
and that still needs to continue to work.  At least this way the code
makes some sense.

6419945e33 This time we have a good set of changes to the core framework that do some
general cleanups, but nothing too major. The majority of the diff goes to
 two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for
 Actions Semi so it takes up some lines to add all the different types, and
 the Qualcomm diff is there because we add support for two SoCs and it's quite
 a bit of data.
 
 Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And
 then the long tail of driver updates for various fixes and stuff follows
 after that.
 
 Core:
  - debugfs cleanups removing error checking and an unused provider API
  - Removal of a clk init typedef that isn't used
  - Usage of match_string() to simplify parent string name matching
  - OF clk helpers moved to their own file (linux/of_clk.h)
  - Make clk warnings more readable across kernel versions
 
 New Drivers:
  - Qualcomm SDM845 GCC and Video clk controllers
  - Qualcomm MSM8998 GCC
  - Actions Semi S900 SoC support
  - Nuvoton npcm750 microcontroller clks
  - Amlogic axg AO clock controller
 
 Removed Drivers:
  - Deprecated Rockchip clk-gate driver
 
 Updates:
  - debugfs functions stopped checking return values
  - Support for the MSIOF module clocks on Rensas R-Car M3-N
  - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
  - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
  - Berlin and Amlogic SPDX tagging
  - Usage of of_clk_get_parent_count() in more places
  - Proper implementation of the CDEV1/2 clocks on Tegra20
  - Allwinner H6 PRCM clock support and R40 EMAC support
  - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet
  - Round closest support for meson's mpll driver
  - Support for meson8b nand clocks and gxbb video decoder clocks
  - Mediatek mali clks
  - STM32MP1 fixes

eafdca4d70 Staging/IIO patches for 4.18-rc1
Here is the big staging and IIO driver update for 4.18-rc1.
 
 It was delayed as I wanted to make sure the final driver deletions did
 not cause any major merge issues, and all now looks good.
 
 There are a lot of patches here, just over 1000.  The diffstat summary
 shows the major changes here:
 	1007 files changed, 16828 insertions(+), 227770 deletions(-)
 Because of this, we might be close to shrinking the overall kernel
 source code size for two releases in a row.
 
 There was loads of work in this release cycle, primarily:
 	- tons of ks7010 driver cleanups
 	- lots of mt7621 driver fixes and cleanups
 	- most driver cleanups
 	- wilc1000 fixes and cleanups
 	- lots and lots of IIO driver cleanups and new additions
 	- debugfs cleanups for all staging drivers
 	- lots of other staging driver cleanups and fixes, the shortlog
 	  has the full details.
 
 but the big user-visable things here are the removal of 3 chunks of
 code:
 	- ncpfs and ipx were removed on schedule, no one has cared about
 	  this code since it moved to staging last year, and if it needs
 	  to come back, it can be reverted.
 	- lustre file system is removed.  I've ranted at the lustre
 	  developers about once a year for the past 5 years, with no
 	  real forward progress at all to clean things up and get the
 	  code into the "real" part of the kernel.  Given that the
 	  lustre developers continue to work on an external tree and try
 	  to port those changes to the in-kernel tree every once in a
 	  while, this whole thing really really is not working out at
 	  all.  So I'm deleting it so that the developers can spend the
 	  time working in their out-of-tree location and get things
 	  cleaned up properly to get merged into the tree correctly at a
 	  later date.
 
 Because of these file removals, you will have merge issues on some of
 these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
 atomisp driver).  Just delete those files, it's a simple merge :)
 
 All of this has been in linux-next for a while with no reported
 problems.
