      vfio: Fix PCI mmap after b3b9c293 · 34002f54
      Alex Williamson authored
      Our mmap path mistakely relied on vma->vm_pgoff to get set in
      remap_pfn_range.  After b3b9c293
      
      , that path only applies to
      copy-on-write mappings.  Set it in our own code.

      Pull pwm changes from Thierry Reding:
       "All legacy PWM providers have now been moved to the PWM subsystem.
        The plan for 3.8 is to adapt all board files to provide a lookup table
        for PWM devices in order to get rid of the global namespace.
        Subsequently, users of the legacy pwm_request() and pwm_free()
        functions can be migrated to the new pwm_get() and pwm_put()
        functions.  Once this has been completed, the legacy API and the
        compatibility code in the core can be removed.
      
        In addition to the above, these changes also add support for
        configuring the polarity of a PWM signal (currently only supported on
        ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
        Managed functions to obtain and release a PWM device (devm_pwm_get()
        and devm_pwm_put()) have been added and the pwm-backlight driver has
        been updated to use them.  If the PWM subsystem hasn't been enabled,
        dummy functions are provided that allow the subsystem to safely
        compile out.
      
        Some common checks on input parameters have been moved to the core and
        removed from the drivers.  Finally, a small fix corrects the
        description of the PWM specifier's second cell in the device tree
        representation."

      Pull scsi target updates from Nicholas Bellinger:
       "Things have been calm for the most part with no new fabric drivers in
        flight for v3.7 (we're up to eight now !), so this update is primarily
        focused on addressing a few long-standing items within target-core and
        iscsi-target fabric code.
      
        The highlights include:
      
         - target: Simplify fabric sense data length handling (roland)
         - qla2xxx: Fix endianness of task management response code (roland)
         - target: fix truncation of mode data, support zero allocation length
           (paolo)
         - target: Properly support zero-length commands in normal processing
           path (paolo)
         - iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT
           PDU (ronnie + nab)
         - iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG
           demo-mode (ronnie + nab)
         - target/file: Re-enable optional fd_buffered_io=1 operation (nab +
           hch)
         - iscsi-target: Add MaxXmitDataSegmenthLength forr target ->
           initiator MDRSL declaration (nab)
         - target: Add target_submit_cmd_map_sgls for SGL fabric memory
           passthrough (nab + hch)
         - tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch +
           nab)
         - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab
           + hch)
      
        The last series for adding a new target_submit_cmd_map_sgls() fabric
        caller (as requested by hch) that accepts pre-allocated SGL memory
        (using existing logic), along with converting tcm_loop + tcm_vhost has
        only been in -next for the last days, but has gotten enough review
        +testing and is clear enough a mechanical change that I think it's
        reasonable to merge for -rc1 code.
      
        Thanks again to everyone who contributed this round! Extra special
        thanks to Roland (PureStorage) for tracking down the qla2xxx target
        TMR response code endian issue, and to Paolo (Redhat) for resolving
        the long standing zero-length CDB issues within target-core between
        virtual and pSCSI backends."

       1) UAPI changes for networking from David Howells
      
       2) A netlink dump is an operation we can sleep within, and therefore we

       5) Fix routing cache removal regression in redirects and IPVS.  The
          core issue on the IPVS side is that it wants to rewrite who the
          nexthop is and we have to explicitly accomodate that case.  From

      RDS: fix rds-ping spinlock recursion · 5175a5e7
      jeff.liu authored
      
      
      This is the revised patch for fixing rds-ping spinlock recursion
      according to Venkat's suggestions.
      
      RDS ping/pong over TCP feature has been broken for years(2.6.39 to
      3.6.0) since we have to set TCP cork and call kernel_sendmsg() between
      ping/pong which both need to lock "struct sock *sk". However, this
      lock has already been hold before rds_tcp_data_ready() callback is
      triggerred. As a result, we always facing spinlock resursion which
      would resulting in system panic.
      
      Given that RDS ping is only used to test the connectivity and not for
      serious performance measurements, we can queue the pong transmit to
      rds_wq as a delayed response.

      Fengguang reported a kernel build failure as following:
      drivers/built-in.o: In function `pch_gbe_ioctl':
      pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write'

      pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write'
      ...
      
      It's a regression by commit da158646
      
      . The root cause is that
      the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK
      can not be set anyway, which finally causes ptp_pch and pch_gbe_main
      build failures.
      
      As David prefers to use *select* to fix such module co-dependency issues,
      this patch explicitly selects all the possible dependencies of PCH_PTP.

      Btrfs: make filesystem read-only when submitting barrier fails · 5af3e8cc
      Stefan Behrens authored
      
      
      So far the return code of barrier_all_devices() is ignored, which
      means that errors are ignored. The result can be a corrupt
      filesystem which is not consistent.
      This commit adds code to evaluate the return code of
      barrier_all_devices(). The normal btrfs_error() mechanism is used to
      switch the filesystem into read-only mode when errors are detected.
      
      In order to decide whether barrier_all_devices() should return
      error or success, the number of disks that are allowed to fail the
      barrier submission is calculated. This calculation accounts for the
      worst RAID level of metadata, system and data. If single, dup or
      RAID0 is in use, a single disk error is already considered to be
      fatal. Otherwise a single disk error is tolerated.
      
      The calculation of the number of disks that are tolerated to fail
      the barrier operation is performed when the filesystem gets mounted,
      when a balance operation is started and finished, and when devices
      are added or removed.
