      Pull AFS updates from David Howells:
       "A set of fix and development patches for AFS for 5.2.
      
        Summary:
      
         - Fix the AFS file locking so that sqlite can run on an AFS mount and
           also so that firefox and gnome can use a homedir that's mounted
           through AFS.
      
           This required emulation of fine-grained locking when the server
           will only support whole-file locks and no upgrade/downgrade. Four
           modes are provided, settable by mount parameter:
      
             "flock=local"   - No reference to the server
      
             "flock=openafs" - Fine-grained locks are local-only, whole-file
                               locks require sufficient server locks
      
             "flock=strict"  - All locks require sufficient server locks
      
             "flock=write"   - Always get an exclusive server lock
      
           If the volume is a read-only or backup volume, then flock=local for
           that volume.
      
         - Log extra information for a couple of cases where the client mucks
           up somehow: AFS vnode with undefined type and dir check failure -
           in both cases we seem to end up with unfilled data, but the issues
           happen infrequently and are difficult to reproduce at will.
      
         - Implement silly rename for unlink() and rename().
      
         - Set i_blocks so that du can get some information about usage.
      
         - Fix xattr handlers to return the right amount of data and to not
           overflow buffers.
      
         - Implement getting/setting raw AFS and YFS ACLs as xattrs"
      
      * tag 'afs-next-20190507' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs:

       "We've got a reasonably broad set of audit patches for the v5.2 merge
        window, the highlights are below:
      
         - The biggest change, and the source of all the arch/* changes, is
           the patchset from Dmitry to help enable some of the work he is
           doing around PTRACE_GET_SYSCALL_INFO.
      
           To be honest, including this in the audit tree is a bit of a
           stretch, but it does help move audit a little further along towards
           proper syscall auditing for all arches, and everyone else seemed to
           agree that audit was a "good" spot for this to land (or maybe they
           just didn't want to merge it? dunno.).
      
         - We can now audit time/NTP adjustments.
      
         - We continue the work to connect associated audit records into a
           single event"

       "Here is the big staging and iio driver update for 5.2-rc1.
      
        Lots of tiny fixes all over the staging and IIO driver trees here,
        along with some new IIO drivers.
      
        The "counter" subsystem was added in here as well, as it is needed by
        the IIO drivers and subsystem.
      
        Also we ended up deleting two drivers, making this pull request remove
        a few hundred thousand lines of code, always a nice thing to see. Both
        of the drivers removed have been replaced with "real" drivers in their
        various subsystem directories, and they will be coming to you from
        those locations during this merge window.
      
        There are some core vt/selection changes in here, that was due to some
        cleanups needed for the speakup fixes. Those have all been acked by
        the various subsystem maintainers (i.e. me), so those are ok.
      
        We also added a few new drivers, for some odd hardware, giving new
        developers plenty to work on with basic coding style cleanups to come
        in the near future.
      
        Other than that, nothing unusual here.
      
        All of these have been in linux-next for a while with no reported

        should be fixed up soon"

       "Here is the "big" set of driver core patches for 5.2-rc1
      
        There are a number of ACPI patches in here as well, as Rafael said
        they should go through this tree due to the driver core changes they
        required. They have all been acked by the ACPI developers.
      
        There are also a number of small subsystem-specific changes in here,
        due to some changes to the kobject core code. Those too have all been
        acked by the various subsystem maintainers.
      
        As for content, it's pretty boring outside of the ACPI changes:
         - spdx cleanups
         - kobject documentation updates
         - default attribute groups for kobjects

      Pull Wimplicit-fallthrough updates from Gustavo A. R. Silva:
       "Mark switch cases where we are expecting to fall through.
      
        This is part of the ongoing efforts to enable -Wimplicit-fallthrough.
      
        Most of them have been baking in linux-next for a whole development
        cycle. And with Stephen Rothwell's help, we've had linux-next
        nag-emails going out for newly introduced code that triggers
        -Wimplicit-fallthrough to avoid gaining more of these cases while we
        work to remove the ones that are already present.
      
        We are getting close to completing this work. Currently, there are
        only 32 of 2311 of these cases left to be addressed in linux-next. I'm
        auditing every case; I take a look into the code and analyze it in
        order to determine if I'm dealing with an actual bug or a false
        positive, as explained here:
      
            https://lore.kernel.org/lkml/c2fad584-1705-a5f2-d63c-824e9b96cf50@embeddedor.com/
      
        While working on this, I've found and fixed the several missing
        break/return bugs, some of them introduced more than 5 years ago.
      
        Once this work is finished, we'll be able to universally enable
        "-Wimplicit-fallthrough" to avoid any of these kinds of bugs from
        entering the kernel again"

      Linus Torvalds authored
      Pull pidfd updates from Christian Brauner:
       "This patchset makes it possible to retrieve pidfds at process creation
        time by introducing the new flag CLONE_PIDFD to the clone() system
        call. Linus originally suggested to implement this as a new flag to
        clone() instead of making it a separate system call.
      
        After a thorough review from Oleg CLONE_PIDFD returns pidfds in the
        parent_tidptr argument. This means we can give back the associated pid
        and the pidfd at the same time. Access to process metadata information
        thus becomes rather trivial.
      
        As has been agreed, CLONE_PIDFD creates file descriptors based on
        anonymous inodes similar to the new mount api. They are made
        unconditional by this patchset as they are now needed by core kernel
        code (vfs, pidfd) even more than they already were before (timerfd,
        signalfd, io_uring, epoll etc.). The core patchset is rather small.
        The bulky looking changelist is caused by David's very simple changes
        to Kconfig to make anon inodes unconditional.
      
        A pidfd comes with additional information in fdinfo if the kernel
        supports procfs. The fdinfo file contains the pid of the process in
        the callers pid namespace in the same format as the procfs status
        file, i.e. "Pid:\t%d".
      
        To remove worries about missing metadata access this patchset comes
        with a sample/test program that illustrates how a combination of
        CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free
        access to process metadata through /proc/<pid>.
      
        Further work based on this patchset has been done by Joel. His work
        makes pidfds pollable. It finished too late for this merge window. I
        would prefer to have it sitting in linux-next for a while and send it
        for inclusion during the 5.3 merge window"

      Current order in open:
      -> Enable interrupts (macb_init_hw)

      -> Start PHY
      
      Sequence of RX handling:
      -> RX interrupt occurs
      -> Interrupt is cleared and interrupt bits disabled in handler
      -> NAPI is scheduled
      -> In NAPI, RX budget is processed and RX interrupts are re-enabled
      
      With the above, on QEMU or fixed link setups (where PHY state doesn't
      matter), there's a chance macb RX interrupt occurs before NAPI is
      enabled. This will result in NAPI being scheduled before it is enabled.
      Fix this macb open by changing the order.

      a flag in driver private data which indicates if offloads apply
      to a shared block at block binding time.

      ====================
      of_get_mac_address ERR_PTR fixes
      
      this patch series is an attempt to fix the mess, I've somehow managed to
      introduce.
      
      First patch in this series is defacto v5 of the previous 05/10 patch in the
      series, but since the v4 of this 05/10 patch wasn't picked up by the
      patchwork for some unknown reason, this patch wasn't applied with the other
      9 patches in the series, so I'm resending it as a separate patch of this
      fixup series again.
      
      Second patch is a result of this rebase against net-next tree, where I was
      checking again all current users of of_get_mac_address and found out, that
      there's new one in DSA, so I've converted this user to the new ERR_PTR
      encoded error value as well.
      
      Third patch which was sent as v5 wasn't considered for merge, but I still
      think, that we need to check for possible NULL value, thus current IS_ERR
      check isn't sufficient and we need to use IS_ERR_OR_NULL instead.
      
      Fourth patch fixes warning reported by kbuild test robot.

      net: ethernet: support of_get_mac_address new ERR_PTR error · a51645f7
      Petr Štetiar authored
      There was NVMEM support added to of_get_mac_address, so it could now
      return ERR_PTR encoded error values, so we need to adjust all current
      users of of_get_mac_address to this new fact.
      
      While at it, remove superfluous is_valid_ether_addr as the MAC address
      returned from of_get_mac_address is always valid and checked by
      is_valid_ether_addr anyway.

      net: usb: smsc: fix warning reported by kbuild test robot · 5503a688

      This patch fixes following warning reported by kbuild test robot:
      
       In function ‘memcpy’,
           inlined from ‘smsc75xx_init_mac_address’ at drivers/net/usb/smsc75xx.c:778:3,
           inlined from ‘smsc75xx_bind’ at drivers/net/usb/smsc75xx.c:1501:2:
       ./include/linux/string.h:355:9: warning: argument 2 null where non-null expected [-Wnonnull]

       drivers/net/usb/smsc75xx.c: In function ‘smsc75xx_bind’:
       ./include/linux/string.h:355:9: note: in a call to built-in function ‘__builtin_memcpy’
      
      I've replaced the offending memcpy with ether_addr_copy, because I'm
      100% sure, that of_get_mac_address can't return NULL as it returns valid
      pointer or ERR_PTR encoded value, nothing else.
      
      I'm hesitant to just change IS_ERR into IS_ERR_OR_NULL check, as this
      would make the warning disappear also, but it would be confusing to
      check for impossible return value just to make a compiler happy.

      staging: octeon-ethernet: Fix of_get_mac_address ERR_PTR check · da48be33
      Petr Štetiar authored
      Commit 284eb160 ("staging: octeon-ethernet: support
      of_get_mac_address new ERR_PTR error") has introduced checking for
      ERR_PTR encoded error value from of_get_mac_address with IS_ERR macro,
      which is not sufficient in this case, as the mac variable is set to NULL
      initialy and if the kernel is compiled without DT support this NULL
      would get passed to IS_ERR, which would lead to the wrong decision and
      would pass that NULL pointer and invalid MAC address further.

      net: dsa: sja1105: Fix status initialization in sja1105_get_ethtool_stats · 8e8673a2
      Nathan Chancellor authored
      Clang warns:
      
      drivers/net/dsa/sja1105/sja1105_ethtool.c:316:39: warning: suggest
      braces around initialization of subobject [-Wmissing-braces]
              struct sja1105_port_status status = {0};
                                                   ^
                                                   {}
      1 warning generated.
      
      One way to fix these warnings is to add additional braces like Clang
      suggests; however, there has been a bit of push back from some
      maintainers[1][2], who just prefer memset as it is unambiguous, doesn't
      depend on a particular compiler version[3], and properly initializes all
      subobjects. Do that here so there are no more warnings.

      vrf: sit mtu should not be updated when vrf netdev is the link · ff6ab32b
      Stephen Suryaputra authored
      VRF netdev mtu isn't typically set and have an mtu of 65536. When the
      link of a tunnel is set, the tunnel mtu is changed from 1480 to the link
      mtu minus tunnel header. In the case of VRF netdev is the link, then the
      tunnel mtu becomes 65516. So, fix it by not setting the tunnel mtu in
      this case.
