Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma update from Doug Ledford:
 "This includes two bugs against the newly added opa vnic that were
  found by turning on the debug kernel options:

   - sleeping while holding a lock, so a one line fix where they
     switched it from GFP_KERNEL allocation to a GFP_ATOMIC allocation

   - a case where they had an isolated caller of their code that could
     call them in an atomic context so they had to switch their use of a
     mutex to a spinlock to be safe, so this was considerably more lines
     of diff because all uses of that lock had to be switched

  In addition, the bug that was discussed with you already about an out
  of bounds array access in ib_uverbs_modify_qp and ib_uverbs_create_ah
  and is only seven lines of diff.

  And finally, one fix to an earlier fix in the -rc cycle that broke
  hfi1 and qib in regards to IPoIB (this one is, unfortunately, larger
  than I would like for a -rc7 submission, but fixing the problem
  required that we not treat all devices as though they had allocated a
  netdev universally because it isn't true, and it took 70 lines of diff
  to resolve the issue, but the final patch has been vetted by Intel and
  Mellanox and they've both given their approval to the fix).

  Summary:

   - Two fixes for OPA found by debug kernel
   - Fix for user supplied input causing kernel problems
   - Fix for the IPoIB fixes submitted around -rc4"

[ Doug sent this having not noticed the 4.12 release, so I guess I'll be
  getting another rdma pull request with the actuakl merge window
  updates and not just fixes.

  Oh well - it would have been nice if this small update had been the
  merge window one.     - Linus ]

ac7b75966c This is the big bulk of pin control changes for the v4.13 series: 
Core:
 
 - The documentation is moved over to RST.
 - We now have agreed bindings for enabling input and output
   buffers without actually enabling input and/or output on a
   pin. We are chiseling out some details of pin control
   electronics.
 
 New drivers:
 
 - ZTE ZX
 - Renesas RZA1
 - MIPS Ingenic JZ47xx: also switch over existing drivers in the
   tree to use this pin controller and consolidate earlier
   spread out code.
 - Microschip MCP23S08: this driver is migrated from the GPIO
   subsystem and totally rewritten to use proper pin control.
   All users are switched over.

Merge tag 'pinctrl-v4.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the big bulk of pin control changes for the v4.13 series:

  Core:
   - The documentation is moved over to RST.
   - We now have agreed bindings for enabling input and output buffers
     without actually enabling input and/or output on a pin. We are
     chiseling out some details of pin control electronics.

  New drivers:
   - ZTE ZX
   - Renesas RZA1
   - MIPS Ingenic JZ47xx: also switch over existing drivers in the tree
     to use this pin controller and consolidate earlier spread out code.
   - Microschip MCP23S08: this driver is migrated from the GPIO
     subsystem and totally rewritten to use proper pin control. All
     users are switched over.

  New subdrivers:
   - Renesas R8A7743 and R8A7745.
   - Allwinner Sunxi A83T R_PIO.
   - Marvell MVEBU Armada CP110 and AP806.

Pull LED updates from Jacek Anaszewski:
 "This time we're removing more than adding:

  Removed drivers:

    leds-versatile:
      - all users of the Versatile LED driver are deleted and replaced
        with the very generic leds-syscon

    leds-sead3:
      - SEAD3 is using the generic leds-syscon & regmap based
        register-bit-led driver

  LED class drivers improvements:

    ledtrig-gpio:
      - use threaded IRQ, which both simplifies the code because we can
        drop the workqueue indirection, and it enables using the trigger
        for GPIOs that work with threaded IRQs themselves
      - refresh LED state after GPIO change since the new GPIO may have
        a different state than the old one

    leds-lp55xx:
      - make various arrays static const

    leds-pca963x:
      - add bindings to invert polarity"

920f2ecdf6 sound updates for 4.13-rc1 
This development cycle resulted in a fair amount of changes in both
 core and driver sides.  The most significant change in ALSA core is
 about PCM.  Also the support of of-graph card and the new DAPM widget
 for DSP are noteworthy changes in ASoC core.  And there're lots of
 small changes splat over the tree, as you can see in diffstat.
 
 Below are a few highlights:
 
 ALSA core:
 - Removal of set_fs() hackery from PCM core stuff, and the code
   reorganization / optimization thereafter
 - Improved support of PCM ack ops, and a new ABI for improved
   control/status mmap handling
 - Lots of constifications in various codes
 
 ASoC core:
 - The support of of-graph card, which may work as a better generic
   device for a replacement of simple-card
 - New widget types intended mainly for use with DSPs
 
 ASoC drivers:
 - New drivers for Allwinner V3s SoCs
 - Ensonic ES8316 codec support
 - More Intel SKL and KBL works
 - More device support for Intel SST Atom (mostly for cheap tablets and
   2-in-1 devices)
 - Support for Rockchip PDM controllers
 - Support for STM32 I2S and S/PDIF controllers
 - Support for ZTE AUD96P22 codecs
 
 HD-audio:
 - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
   for HP and Dell machines
 - A few more fixes for i915 component binding
 
 Note that of-graph change may bring the conflicts with a later pull
 request of devicetree, as currently found in linux-next.

Pull mnt namespace updates from Eric Biederman:
 "A big break-through came during this development cycle as a way was
  found to maintain the existing umount -l semantics while allowing for
  optimizations that improve the performance. That is represented by the
  first change in this series moving the reparenting of mounts into
  their own pass. This has allowed addressing the horrific performance
  of umount -l on a carefully crafted tree of mounts with locks held
  (0.06s vs 60s in my testing). What allowed this was not changing where
  umounts propagate to while propgating umounts.

  The next change fixes the case where the order of the mount whose
  umount are being progated visits a tree where the mounts are stacked
  upon each other in another order. This is weird but not hard to
  implement.

  The final change takes advantage of the unchanging mount propgation
  tree to skip parts of the mount propgation tree that have already been
  visited. Yielding a very nice speed up in the worst case.

  There remains one outstanding question about the semantics of umount -l
  that I am still discussiong with Ram Pai. In practice that area of the
  semantics was changed by 1064f874ab ("mnt: Tuck mounts under others
  instead of creating shadow/side mounts.") and no regressions have been
  reported. Still I intend to finish talking that out with him to ensure
  there is not something a more intense use of mount propagation in the
  future will not cause to become significant"

  mnt: Make propagate_umount less slow for overlapping mount propagation trees

c96e6dabfb We've got eight GFS2 patches for this merge window: 
1. Andreas Gruenbacher has four patches related to cleaning up the GFS2
    inode evict process. This is about half of his patches designed to
    fix a long-standing GFS2 hang related to the inode shrinker.
    (Shrinker calls gfs2 evict, evict calls DLM, DLM requires memory
    and blocks on the shrinker.) These 4 patches have been well tested.
    His second set of patches are still being tested, so I plan to hold
    them until the next merge window, after we have more weeks of testing.
    The first patch eliminates the flush_delayed_work, which can block.
 2. Andreas's second patch protects setting of gl_object for rgrps with
    a spin_lock to prevent proven races.
 3. His third patch introduces a centralized mechanism for queueing glock
    work with better reference counting, to prevent more races.
 4. His fourth patch retains a reference to inode glocks when an error
    occurs while creating an inode. This keeps the subsequent evict from
    needing to reacquire the glock, which might call into DLM and block
    in low memory conditions.
 5. Arvind Yadav has a patch to add const to attribute_group structures.
 6. I have a patch to detect directory entry inconsistencies and withdraw
    the file system if any are found. Better that than silent corruption.
 7. I have a patch to remove a vestigial variable from glock structures,
    saving some slab space.
 8. I have another patch to remove a vestigial variable from the GFS2
    in-core superblock structure.

3908c9839b dm zoned: fix overflow when converting zone ID to sectors 
A zone ID is a 32 bits unsigned int which can overflow when doing the
bit shifts in dmz_start_sect().  With a 256 MB zone size drive, the
overflow happens for a zone ID >= 8192.

Fix this by casting the zone ID to a sector_t before doing the bit
shift.  While at it, similarly fix dmz_start_block().

b4b8cbf679 Cavium CNN55XX: fix broken default Kconfig entry 
Every developer always thinks that _their_ code is so special and
magical that it should be enabled by default.

And most of them are completely and utterly wrong.  That's definitely
the case when you write a specialty driver for a very unsual "security
processor". It does *not* get to mark itself as "default m".

If you solve world hunger, and make a driver that cures people of
cancer, by all means enable it by default.  But afaik, the Cavium
CNN55XX does neither.

Pull GCC plugin updates from Kees Cook:
 "The big part is the randstruct plugin infrastructure.

  This is the first of two expected pull requests for randstruct since
  there are dependencies in other trees that would be easier to merge
  once those have landed. Notably, the IPC allocation refactoring in
  -mm, and many trivial merge conflicts across several trees when
  applying the __randomize_layout annotation.

  As a result, it seemed like I should send this now since it is
  relatively self-contained, and once the rest of the trees have landed,
  send the annotation patches. I'm expecting the final phase of
  randstruct (automatic struct selection) will land for v4.14, but if
  its other tree dependencies actually make it for v4.13, I can send
  that merge request too.

  Summary:

  - typo fix in Kconfig (Jean Delvare)

  - randstruct infrastructure"

Pull security layer updates from James Morris:

 - a major update for AppArmor. From JJ:

     * several bug fixes and cleanups

     * the patch to add symlink support to securityfs that was floated
       on the list earlier and the apparmorfs changes that make use of
       securityfs symlinks

     * it introduces the domain labeling base code that Ubuntu has been
       carrying for several years, with several cleanups applied. And it
       converts the current mediation over to using the domain labeling
       base, which brings domain stacking support with it. This finally
       will bring the base upstream code in line with Ubuntu and provide
       a base to upstream the new feature work that Ubuntu carries.

     * This does _not_ contain any of the newer apparmor mediation
       features/controls (mount, signals, network, keys, ...) that
       Ubuntu is currently carrying, all of which will be RFC'd on top
       of this.

 - Notable also is the Infiniband work in SELinux, and the new file:map
   permission. From Paul:

      "While we're down to 21 patches for v4.13 (it was 31 for v4.12),
       the diffstat jumps up tremendously with over 2k of line changes.

       Almost all of these changes are the SELinux/IB work done by
       Daniel Jurgens; some other noteworthy changes include a NFS v4.2
       labeling fix, a new file:map permission, and reporting of policy
       capabilities on policy load"

   There's also now genfscon labeling support for tracefs, which was
   lost in v4.1 with the separation from debugfs.

 - Smack incorporates a safer socket check in file_receive, and adds a
   cap_capable call in privilege check.

 - TPM as usual has a bunch of fixes and enhancements.

 - Multiple calls to security_add_hooks() can now be made for the same
   LSM, to allow LSMs to have hook declarations across multiple files.

 - IMA now supports different "ima_appraise=" modes (eg. log, fix) from
   the boot command line.

4fd1a57952 gfs2: Get rid of flush_delayed_work in gfs2_evict_inode 
So far, gfs2_evict_inode clears gl->gl_object and then flushes the glock
work queue to make sure that inode glops which dereference gl->gl_object
have finished running before the inode is destroyed.  However, flushing
the work queue may do more work than needed, and in particular, it may
call into DLM, which we want to avoid here.  Use a bit lock
(GIF_GLOP_PENDING) to synchronize between the inode glops and
gfs2_evict_inode instead to get rid of the flushing.

In addition, flush the work queues of existing glocks before reusing
them for new inodes to get those glocks into a known state: the glock
state engine currently doesn't handle glock re-appropriation correctly.
(We may be able to fix the glock state engine instead later.)

There are some boards which have the pin strapped this way and need
software workaround suggested by the data manual. Bit[7] of
Configuration Register 4 (address 0x0031) must be cleared to 0. This
ensures proper operation of the PHY.

Implement driver support for device-tree property meant to advertise
the wrong strapping.

It further advises that if a board has this pin strapped in mode 1 and

Since it is not possible to detect in software if RX_DV/RX_CTRL pin is
incorrectly strapped, add a device-tree property for the board to
advertise this and allow corrective action in software.

64a919a944 nfp: default to chained metadata prepend format 
ABI 4.x introduced the chained metadata format and made it the
only one possible.  There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath.  In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities.  The default was left to non-chained.

In case of fallback traffic, there is no capability telling the
driver there may be chained metadata.  With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.

This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway.  New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

2eb333c4b4 nfp: improve order of interfaces in breakout mode 
For historical reasons we enumerate the vNICs in order.  This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.

What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.

Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:

pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2

Note that behaviour of phys_port_id is not changed since there is
a separate id number for the subport there.
