      Pull tracing fix from Steven Rostedt:
       "During the merge window I added a new file that is used to filter
        trace events on pids.  It filters all events where only tasks with
        their pid in that file exists.  It also handles the sched_switch and
        sched_wakeup trace events where the current task does not have its pid
        in the file, but the task either being switched to or awaken does.
      
        Unfortunately, I forgot about sched_wakeup_new and sched_waking.  Both
        of these tracepoints use the same class as the sched_wakeup
        tracepoint, and they too should be included in what gets filtered by
        the set_event_pid file"

       "There's one fix for the core here, we weren't reinitialising the
        actual transferred length in messages when they get reused which meant
        that we'd just keep adding to the length if a message is reused.  This
        has limited impact since it's only used in error handling cases but
        will really mess anything that tries to use it up when it triggers.
      
        As ever there's a small collection of driver specific fixes too"

      tracing: Add sched_wakeup_new and sched_waking tracepoints for pid filter · 0f72e37e
      Steven Rostedt (Red Hat) authored
      
      
      The set_event_pid filter relies on attaching to the sched_switch and
      sched_wakeup tracepoints to see if it should filter the tracing on schedule
      tracepoints. By adding the callbacks to sched_wakeup, pids in the
      set_event_pid file will trace the wakeups of those tasks with those pids.
      
      But sched_wakeup_new and sched_waking were missed. These two should also be
      traced. Luckily, these tracepoints share the same class as sched_wakeup
      which means they can use the same pre and post callbacks as sched_wakeup
      does.

       "I found two minor bugs while doing development on the ring buffer
        code.
      
        The first is something that's been there since its creation.  If a
        reader reads a page out of the ring buffer before there's any events
        on it, it can get an out of date timestamp for that event.  It may be
        off by a few microseconds, more if the first event gets discarded.
        The fix was to only update the reader time stamp when it actually sees
        an event on the page, instead of just reading the timestamp from the
        page even if it has no events on it.  That timestamp is still volatile
        until an event is present.
      
        The second bug is more recent.  Instead of passing around parameters a
        descriptor was made and the parameters are passed via a single
        descriptor.  This simplified the code a bit.  But there was one place
        that expected the parameter to be passed by value not reference (which
        a descriptor now does).  And it added to the length of the event,
        which may be ignored later, but the length should not have been
        increased.  The only real problem with this bug is that it may
        allocate more than was needed for the event"

      gpio: omap: drop omap1 mpuio specific irq_mask/unmask callbacks · 000255b7
      Grygorii Strashko authored
      Originally OMAP MPUIO GPIO irqchip was implemented using Generic irq
      chip, but after set of reworks Generic irq chip code was replaced by
      common OMAP GPIO implementation and finally removed by
      commit d2d05c65 ("gpio: omap: Fix regression for MPUIO interrupts").
      Unfortunately, above commit left .irq_mask/unmask callbacks assigned
      as below for MPUIO GPIO case:
      	irqc->irq_mask = irq_gc_mask_set_bit;
      	irqc->irq_unmask = irq_gc_mask_clr_bit;
      
      This now causes boot failure on OMAP1 platforms, after
      commit 450fa54c ("gpio: omap: convert to use generic irq handler")
      which forces these callbacks to be called during GPIO IRQs mapping
      from gpiochip_irq_map:

      This is caused by the fact that at the moment some GPIO names are set
      to NULL, there is a hole in linear representation of one GPI bank, see
      drivers/gpio/gpio-lpc32xx.c / gpi_p3_names[] for details.
      
      The same problem most probably affects also gpio-cs5535.c, see
      cs5535_gpio_names[].

      target: fix COMPARE_AND_WRITE non zero SGL offset data corruption · d94e5a61
      Jan Engelhardt authored
      
      
      target_core_sbc's compare_and_write functionality suffers from taking
      data at the wrong memory location when writing a CAW request to disk
      when a SGL offset is non-zero.
      
      This can happen with loopback and vhost-scsi fabric drivers when
      SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space
      SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers.
      
      Given the following sample LIO subtopology,
      
      % targetcli ls /loopback/
      o- loopback ................................. [1 Target]
        o- naa.6001405ebb8df14a ....... [naa.60014059143ed2b3]
          o- luns ................................... [2 LUNs]
            o- lun0 ................ [iblock/ram0 (/dev/ram0)]
            o- lun1 ................ [iblock/ram1 (/dev/ram1)]
      % lsscsi -g

      the following bug can be observed in Linux 4.3 and 4.4~rc1:
      
      % perl -e 'print chr$_ for 0..255,reverse 0..255' >rand

      Rather than writing all-zeroes as instructed with the -D file, it
      corrupts the data in the sector by splicing some of the original
      bytes in. The page of the first entry of cmd->t_data_sg includes the
      CDB, and sg->offset is set to a position past the CDB. I presume that
      sg->offset is also the right choice to use for subsequent sglist
      members.

      target: Fix race for SCF_COMPARE_AND_WRITE_POST checking · 057085e5
      Nicholas Bellinger authored
      
      
      This patch addresses a race + use after free where the first
      stage of COMPARE_AND_WRITE in compare_and_write_callback()
      is rescheduled after the backend sends the secondary WRITE,
      resulting in second stage compare_and_write_post() callback
      completing in target_complete_ok_work() before the first
      can return.
      
      Because current code depends on checking se_cmd->se_cmd_flags
      after return from se_cmd->transport_complete_callback(),
      this results in first stage having SCF_COMPARE_AND_WRITE_POST
      set, which incorrectly falls through into second stage CAW
      processing code, eventually triggering a NULL pointer
      dereference due to use after free.
      
      To address this bug, pass in a new *post_ret parameter into
      se_cmd->transport_complete_callback(), and depend upon this
      value instead of ->se_cmd_flags to determine when to return
      or fall through into ->queue_status() code for CAW.

      iscsi-target: Fix rx_login_comp hang after login failure · ca82c2bd
      Nicholas Bellinger authored
      This patch addresses a case where iscsi_target_do_tx_login_io()
      fails sending the last login response PDU, after the RX/TX
      threads have already been started.
      
      The case centers around iscsi_target_rx_thread() not invoking
      allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs
      from the failure path, resulting in RX thread hanging
      indefinately on iscsi_conn->rx_login_comp.

      ARM: 8454/1: OF implies OF_FLATTREE · aa7d5f18
      Arnd Bergmann authored
      
      
      On the ARM architecture, individual platforms select CONFIG_USE_OF if they
      need it, but all device tree code is keyed off CONFIG_OF. When building
      a platform without DT support and manually enabling CONFIG_OF, we now
      get a number of build errors, e.g.
      
      arch/arm/kernel/devtree.c: In function 'setup_machine_fdt':
      arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration]
      
      We could now try to separate the use case of booting from DT vs. the
      case of using the dynamic implementation, but that seems more complicated
      than it can gain us.
      
      This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM
      and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little
      extra code when we just want the dynamic OF implementation, but that seems
      like a rather obscure case, and this version solves all CONFIG_OF related
      randconfig regressions.

         - Fix a number of issues with the NFSv4.2 CLONE ioctl()
         - Properly set NFS v4.2 NFSDBG_FACILITY
         - NFSv4 referrals are broken; Cleanup FATTR4_WORD0_FS_LOCATIONS after
           decoding success
         - Use sliding delay when LAYOUTGET gets NFS4ERR_DELAY
         - Ensure that attrcache is revalidated after a SETATTR"
