      Pull XFS updates from Darrick Wong:
       "Here are the changes for xfs for 4.14. Most of these are cleanups and
        fixes for bad behavior, as we're mostly focusing on improving
        reliablity this cycle (read: there's potentially a lot of stuff on the
        horizon for 4.15 so better to spend a few weeks killing other bugs
        now).
      
        Summary:
      
         - Write unmount record for a ro mount to avoid unnecessary log replay
      
         - Clean up orphaned inodes when mounting fs readonly

         - Fix log recovery corruption problems when log headers wrap around
           the end
      
         - Avoid infinite loop searching for free inodes when inode counters
           are wrong
      
         - Evict inodes involved with log redo so that we don't leak them
           later
      
         - Fix a potential race between reclaim and inode cluster freeing
      
         - Refactor the inode joining code w.r.t. transaction rolling &
           deferred ops
      
         - Fix a bug where the log doesn't properly deal with dirty buffers
           that are about to become ordered buffers
      
         - Fix the extent swap code to deal with making dirty buffers ordered
           properly
      
         - Consolidate page fault handlers
      
         - Refactor the incore extent manipulation functions to use the iext
           abstractions instead of directly modifying with extent data
      
         - Disable crashy chattr +/-x until we fix it
      
         - Don't allow us to set S_DAX for v2 inodes
      
         - Various cleanups
      
         - Clarify some documentation
      
         - Fix a problem where fsync and a log commit race to send the disk a
           flush command, resulting in a small window where power fail data
           loss could occur
      
         - Simplify some rmap operations in the fcollapse code
      
         - Fix some use-after-free problems in async writeback"

      Linus Torvalds authored
      Pull GFS2 updates from Bob Peterson:
       "We've got a whopping 29 GFS2 patches for this merge window, mainly
        because we held some back from the previous merge window until we
        could get them perfected and well tested. We have a couple patch sets,
        including my patch set for protecting glock gl_object and Andreas
        Gruenbacher's patch set to fix the long-standing shrink- slab hang,
        plus a bunch of assorted bugs and cleanups.
      
        Summary:
      
         - I fixed a bug whereby an IO error would lead to a double-brelse.
      
         - Andreas Gruenbacher made a minor cleanup to call his relatively new
           function, gfs2_holder_initialized, rather than doing it manually.
           This was just missed by a previous patch set.
      
         - Jan Kara fixed a bug whereby the SGID was being cleared when
           inheriting ACLs.
      
         - Andreas found a bug and fixed it in his previous patch, "Get rid of
           flush_delayed_work in gfs2_evict_inode". A call to
           flush_delayed_work was deleted from *gfs2_inode_lookup and added to
           gfs2_create_inode.
      
         - Wang Xibo found and fixed a list_add call in inode_go_lock that
           specified the parameters in the wrong order.
      
         - Coly Li submitted a patch to add the REQ_PRIO to some of GFS2's
           metadata reads that were accidentally missing them.
      
         - I submitted a 4-patch set to protect the glock gl_object field.
           GFS2 was setting and checking gl_object with no locking mechanism,
           so the value was occasionally stomped on, which caused file system
           corruption.
      
         - I submitted a small cleanup to function gfs2_clear_rgrpd. It was
           needlessly adding rgrp glocks to the lru list, then pulling them
           back off immediately. The rgrp glocks don't use the lru list
           anyway, so doing so was just a waste of time.
      
         - I submitted a patch that checks the GLOF_LRU flag on a glock before
           trying to remove it from the lru_list. This avoids a lot of
           unnecessary spin_lock contention.
      
         - I submitted a patch to delete GFS2's debugfs files only after we
           evict all the glocks. Before this patch, GFS2 would delete the
           debugfs files, and if unmount hung waiting for a glock, there was
           no way to debug the problem. Now, if a hang occurs during umount,
           we can examine the debugfs files to figure out why it's hung.
      
         - Andreas Gruenbacher submitted a patch to fix some trivial typos.
      
         - Andreas also submitted a five-part patch set to fix the
           longstanding hang involving the slab shrinker: dlm requires memory,
           calls the inode shrinker, which calls gfs2's evict, which calls
           back into DLM before it can evict an inode.
      
         - Abhi Das submitted a patch to forcibly flush the active items list
           to relieve memory pressure. This fixes a long-standing bug whereby
           GFS2 was getting hung permanently in balance_dirty_pages.
      
         - Thomas Tai submitted a patch to fix a slab corruption problem due
           to a residual pointer left in the lock_dlm lockstruct.
      
         - I submitted a patch to withdraw the file system if IO errors are
           encountered while writing to the journals or statfs system file
           which were previously not being sent back up. Before, some IO
           errors were sometimes not be detected for several hours, and at
           recovery time, the journal errors made journal replay impossible.
      
         - Andreas has a patch to fix an annoying format-truncation compiler
           warning so GFS2 compiles cleanly.
      
         - I have a patch that fixes a handful of sparse compiler warnings.
      
         - Andreas fixed up an useless gl_object warning caused by an earlier
           patch.
      
         - Arvind Yadav added a patch to properly constify our rhashtable
           params declare.
      
         - I added a patch to fix a regression caused by the non-recursive
           delete and truncate patch that caused file system blocks to not be
           properly freed.
      
         - Ernesto A. Fernández added a patch to fix a place where GFS2 would
           send back the wrong return code setting extended attributes.
      
         - Ernesto also added a patch to fix a case in which GFS2 was
           improperly setting an inode's i_mode, potentially granting access
           to the wrong users"

      Intel Wired LAN Driver Updates 2017-09-05
      
      This series contains fixes for i40e only.
      
      These two patches fix an issue where our nvmupdate tool does not work on RHEL 7.4
      and newer kernels, in fact, the use of the nvmupdate tool on newer kernels can
      cause the cards to be non-functional unless these patches are applied.
      
      Anjali reworks the locking around accessing the NVM so that NVM acquire timeouts
      do not occur which was causing the failed firmware updates.
      
      Jake correctly updates the wb_desc when reading the NVM through the AdminQ.

      i40e: avoid NVM acquire deadlock during NVM update · 09f79fd4
      Anjali Singhai Jain authored
      X722 devices use the AdminQ to access the NVM, and this requires taking
      the AdminQ lock. Because of this, we lock the AdminQ during
      i40e_read_nvm(), which is also called in places where the lock is
      already held, such as the firmware update path which wants to lock once
      and then unlock when finished after performing several tasks.
      
      Although this should have only affected X722 devices, commit
      96a39aed ("i40e: Acquire NVM lock before reads on all devices",
      2016-12-02) added locking for all NVM reads, regardless of device
      family.
      
      This resulted in us accidentally causing NVM acquire timeouts on all
      devices, causing failed firmware updates which left the eeprom in
      a corrupt state.
      
      Create unsafe non-locked variants of i40e_read_nvm_word and
      i40e_read_nvm_buffer, __i40e_read_nvm_word and __i40e_read_nvm_buffer
      respectively. These variants will not take the NVM lock and are expected
      to only be called in places where the NVM lock is already held if
      needed.
      
      Since the only caller of i40e_read_nvm_buffer() was in such a path,
      remove it entirely in favor of the unsafe version. If necessary we can
      always add it back in the future.
      
      Additionally, we now need to hold the NVM lock in i40e_validate_checksum
      because the call to i40e_calc_nvm_checksum now assumes that the NVM lock
      is held. We can further move the call to read I40E_SR_SW_CHECKSUM_WORD
      up a bit so that we do not need to acquire the NVM lock twice.
      
      This should resolve firmware updates and also fix potential raise that
      could have caused the driver to report an invalid NVM checksum upon
      driver load.

      vhost_net: correctly check tx avail during rx busy polling · 8b949bef
      Jason Wang authored
      We check tx avail through vhost_enable_notify() in the past which is
      wrong since it only checks whether or not guest has filled more
      available buffer since last avail idx synchronization which was just
      done by vhost_vq_avail_empty() before. What we really want is checking
      pending buffers in the avail ring. Fix this by calling
      vhost_vq_avail_empty() instead.
      
      This issue could be noticed by doing netperf TCP_RR benchmark as
      client from guest (but not host). With this fix, TCP_RR from guest to
      localhost restores from 1375.91 trans per sec to 55235.28 trans per
      sec on my laptop (Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz).

      rxrpc: Make service connection lookup always check for retry · fdade4f6
      David Howells authored
      When an RxRPC service packet comes in, the target connection is looked up
      by an rb-tree search under RCU and a read-locked seqlock; the seqlock retry
      check is, however, currently skipped if we got a match, but probably
      shouldn't be in case the connection we found gets replaced whilst we're
      doing a search.
      
      Make the lookup procedure always go through need_seqretry(), even if the
      lookup was successful.  This makes sure we always pick up on a write-lock
      event.
      
      On the other hand, since we don't take a ref on the object, but rely on RCU
      to prevent its destruction after dropping the seqlock, I'm not sure this is
      necessary.

      Claudiu Manoil authored
      The wrong register is checked for the Tx flow control bit,
      it should have been maccfg1 not maccfg2.
      This went unnoticed for so long probably because the impact is
      hardly visible, not to mention the tangled code from adjust_link().
      First, link flow control (i.e. handling of Rx/Tx link level pause frames)
      is disabled by default (needs to be enabled via 'ethtool -A').
      Secondly, maccfg2 always returns 0 for tx_flow_oldval (except for a few
      old boards), which results in Tx flow control remaining always on
      once activated.

           in order to address a boot crash on some systems with Thunderbolt
           devices connected at boot time where we miss an early hotplug event
           due to a delay in GPE enabling (Rafael Wysocki).
      
         - Rework the handling of PCI bridges when setting up ACPI-based

      Pull power management updates from Rafael Wysocki:
       "This time (again) cpufreq gets the majority of changes which mostly
        are driver updates (including a major consolidation of intel_pstate),
        some schedutil governor modifications and core cleanups.
      
        There also are some changes in the system suspend area, mostly related
        to diagnostics and debug messages plus some renames of things related
        to suspend-to-idle. One major change here is that suspend-to-idle is
        now going to be preferred over S3 on systems where the ACPI tables
        indicate to do so and provide requsite support (the Low Power Idle S0
        _DSM in particular). The system sleep documentation and the tools
        related to it are updated too.
      
        The rest is a few cpuidle changes (nothing major), devfreq updates,
        generic power domains (genpd) framework updates and a few assorted
        modifications elsewhere.
      
        Specifics:
      
         - Drop the P-state selection algorithm based on a PID controller from
           intel_pstate and make it use the same P-state selection method
           (based on the CPU load) for all types of systems in the active mode
           (Rafael Wysocki, Srinivas Pandruvada).
      
         - Rework the cpufreq core and governors to make it possible to take
           cross-CPU utilization updates into account and modify the schedutil
           governor to actually do so (Viresh Kumar).
      
         - Clean up the handling of transition latency information in the
           cpufreq core and untangle it from the information on which drivers
           cannot do dynamic frequency switching (Viresh Kumar).
      
         - Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek
           cpufreq driver and update its DT bindings (Sean Wang).
      
         - Modify the cpufreq dt-platdev driver to autimatically create
           cpufreq devices for the new (v2) Operating Performance Points (OPP)
           DT bindings and update its whitelist of supported systems (Viresh
           Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley
           Xiao).
      
         - Add support for Ux500 to the cpufreq-dt driver and drop the
           obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
      
         - Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
           Nguyen).
      
         - Fix and clean up assorted issues in the cpufreq drivers and core
           (Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
           Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
      
         - Update the IO-wait boost handling in the schedutil governor to make
           it less aggressive (Joel Fernandes).
      
         - Rework system suspend diagnostics to make it print fewer messages
           to the kernel log by default, add a sysfs knob to allow more
           suspend-related messages to be printed and add Low Power S0 Idle
           constraints checks to the ACPI suspend-to-idle code (Rafael
           Wysocki, Srinivas Pandruvada).
      
         - Prefer suspend-to-idle over S3 on ACPI-based systems with the
           ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
           interface present in the ACPI tables (Rafael Wysocki).
      
         - Update documentation related to system sleep and rename a number of
           items in the code to make it cleare that they are related to
           suspend-to-idle (Rafael Wysocki).
      
         - Export a variable allowing device drivers to check the target
           system sleep state from the core system suspend code (Florian
           Fainelli).
      
         - Clean up the cpuidle subsystem to handle the polling state on x86
           in a more straightforward way and to use %pOF instead of full_name
           (Rafael Wysocki, Rob Herring).
      
         - Update the devfreq framework to fix and clean up a few minor issues
           (Chanwoo Choi, Rob Herring).
      
         - Extend diagnostics in the generic power domains (genpd) framework
           and clean it up slightly (Thara Gopinath, Rob Herring).
      
         - Fix and clean up a couple of issues in the operating performance
           points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).
      
         - Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling
           (AVS) driver (David Wu).
      
         - Fix the usage of notifiers in CPU power management on some
           platforms (Alex Shi).
      
         - Update the pm-graph system suspend/hibernation and boot profiling
           utility (Todd Brandt).

      ====================
      net: dsa: Allow switch drivers to indicate number of TX queues
      
      This patch series extracts the parts of the patch set that are likely not to be
      controversial and actually bringing multi-queue support to DSA-created network
      devices.
      
      With these patches, we can now use sch_multiq as documented under
      Documentation/networking/multique.txt and let applications dedice the switch
      port output queue they want to use. Currently only Broadcom tags utilize that
      information.
      
      Resending based on David's feedback regarding the patches not in patchwork.
      
      Changes in v2:
      - use a proper define for the number of TX queues in bcm_sf2.c (Andrew)
      
      Changes from RFC:
      
      - dropped the ability to configure RX queues since we don't do anything with
        those just yet
      - dropped the patches that dealt with binding the DSA slave network devices
        queues with their master network devices queues this will be worked on
        separately.

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of the GPIO changes for the v4.14 cycle.
      
        Not so much changes this time, phew. David Daney and Bartosz
        Golaszewski did all the really interesting work in infrastructure
        improvement across GPIO and IRQ core, hats off for them and to tglx
        and Marc Z for general help with these patch sets.
      
        Core changes:
      
         - Allow the GPIO irqchip to allocate IRQs dynamically. This is an
           important change on systems where only a restricted number of IRQs,
           lesser than the number of GPIO lines, can be utilized. Now we can
           allocate these on a first-come-first-served basis instead of
           hogging up valuable IRQ lines.
      
         - Serious fix-up of the kerneldoc documentation and inclusion into
           the kerneldoc builds.
      
         - Pulled in the IRQ simulator from the IRQ core tree and use this in
           the GPIO mockup driver for exhaustive testing of interrupt
           abilities.
      
        New drivers:
      
         - New driver for ThunderX and OCTEON-TX. This is especially
           interesting as it picks up improvements from the IRQ core that
           allow us to handle fasteoi ACKs upwards in a hierarchy when there
           are IRQ flag latches on several levels in a hierarchy. Very
           interesting work here.
      
         - New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
      
        Misc:
      
         - Several fixes and improvements for Xilinx Zynq GPIO.
      
         - Support an enablement GPIO for the 74x164 GPIO.
      
         - Switch a bunch of chips to use devres to allocate irq descriptors.
      
         - A bunch of constification fixes"
