      nvme: make NVME_RDMA depend on BLOCK · bd0b841f
      Linus Torvalds 提交于
      Commit aa719874 ("nvme: fabrics drivers don't need the nvme-pci
      driver") removed the dependency on BLK_DEV_NVME, but the cdoe does
      depend on the block layer (which used to be an implicit dependency
      through BLK_DEV_NVME).
      
      Otherwise you get various errors from the kbuild test robot random
      config testing when that happens to hit a configuration with BLOCK
      device support disabled.

           performance for the device-dax interface.  The device-dax interface

           understand DAX pmd entries.  This fix is tagged for -stable.
      
         - Fix a mis-merge of the nfit machine-check handler to flip the
           polarity of an if() to match the final version of the patch that
           Vishal sent for 4.8-rc1.  Without this the nfit machine check
           handler never detects / inserts new 'badblocks' entries which
           applications use to identify lost portions of files.
      
         - For test purposes, fix the nvdimm_clear_poison() path to operate on
           legacy / simulated nvdimm memory ranges.  Without this fix a test
           can set badblocks, but never clear them on these ranges.
      
         - Fix the range checking done by dax_dev_pmd_fault().  This is not
           tagged for -stable since this problem is mitigated by specifying
           aligned resources at device-dax setup time.

      Second set of IIO fixes for the 4.8 cycle.
      
      We have a big rework of the kxsd9 driver queued up behind the fix below and
      a fix for a recent fix that was marked for stable.
      Hence this fix series is perhaps a little more urgent than average for IIO.
      * core
        - a fix for a fix in the last set.  The recent fix for blocking ops when
         ! task running left a path (unlikely one) in which the function return
         value was not set - so initialise it to 0.
        - The IIO_TYPE_FRACTIONAL code previously didn't cope with negative
        fractions.  Turned out a fix for this was in Analog's tree but hadn't made
        it upstream.
      * bmc150
        - reset chip at init time. At least one board out there ends up coming up
        in an unstable state due to noise during power up.  The reset does no
        harm on other boards.
      * kxsd9
        - Fix a bug in the reported scaling due to failing to set the integer
        part to 0.
      * hid-sensors-pressure
        - Output was in the wrong units to comply with the IIO ABI.
      * tools
        - iio_generic_buffer: Fix the trigger-less mode by ensuring we don't fault
          out for having no trigger when we explicitly said we didn't want to have
          one.

      arm64: use preempt_disable_notrace in _percpu_read/write · 2b974344
      Chunyan Zhang 提交于
      When debug preempt or preempt tracer is enabled, preempt_count_add/sub()
      can be traced by function and function graph tracing, and
      preempt_disable/enable() would call preempt_count_add/sub(), so in Ftrace
      subsystem we should use preempt_disable/enable_notrace instead.
      
      In the commit 345ddcc8 ("ftrace: Have set_ftrace_pid use the bitmap
      like events do") the function this_cpu_read() was added to
      trace_graph_entry(), and if this_cpu_read() calls preempt_disable(), graph
      tracer will go into a recursive loop, even if the tracing_on is
      disabled.
      
      So this patch change to use preempt_enable/disable_notrace instead in
      this_cpu_read().
      
      Since Yonghui Yang helped a lot to find the root cause of this problem,
      so also add his SOB.

      arm64: spinlocks: implement smp_mb__before_spinlock() as smp_mb() · 872c63fb
      Will Deacon 提交于
      smp_mb__before_spinlock() is intended to upgrade a spin_lock() operation
      to a full barrier, such that prior stores are ordered with respect to
      loads and stores occuring inside the critical section.
      
      Unfortunately, the core code defines the barrier as smp_wmb(), which
      is insufficient to provide the required ordering guarantees when used in
      conjunction with our load-acquire-based spinlock implementation.
      
      This patch overrides the arm64 definition of smp_mb__before_spinlock()
      to map to a full smp_mb().

      usb: chipidea: udc: fix NULL ptr dereference in isr_setup_status_phase · 6f3c4fb6
      Clemens Gruber 提交于
      Problems with the signal integrity of the high speed USB data lines or
      noise on reference ground lines can cause the i.MX6 USB controller to
      violate USB specs and exhibit unexpected behavior.
      
      It was observed that USBi_UI interrupts were triggered first and when
      isr_setup_status_phase was called, ci->status was NULL, which lead to a
      NULL pointer dereference kernel panic.
      
      This patch fixes the kernel panic, emits a warning once and returns
      -EPIPE to halt the device and let the host get stalled.
      It also adds a comment to point people, who are experiencing this issue,
      to their USB hardware design.

      i2c: rk3x: Restore clock settings at resume time · cbfff439
      Doug Anderson 提交于
      Depending on a number of factors including:
      - Which exact Rockchip SoC we're working with
      - How deep we suspend
      - Which i2c port we're on
      
      We might lose the state of the i2c registers at suspend time.
      Specifically we've found that on rk3399 the i2c ports that are not in
      the PMU power domain lose their state with the current suspend depth
      configured by ARM Tursted Firmware.
      
      Note that there are very few actual i2c registers that aren't configured
      per transfer anyway so all we actually need to re-configure are the
      clock config registers.  We'll just add a call to rk3x_i2c_adapt_div()
      at resume time and be done with it.
      
      NOTE: On rk3399 on ports whose power was lost, I put printouts in at
      resume time.  I saw things like:
        before: con=0x00010300, div=0x00060006

      i2c: designware: save the preset value of DW_IC_SDA_HOLD · 664d58bf
      Zhuo-hao Lee 提交于
      There are several ways to set the SDA hold time for i2c controller,
      including: Device Tree, built-in device properties and ACPI. However,
      if the SDA hold time is not specified by above method, we should
      read the value, where it is preset by firmware, and save it to
      sda_hold_time. This is needed because when i2c controller enters
      runtime suspend, the DW_IC_SDA_HOLD value will be reset to chipset
      default value. And during runtime resume, i2c_dw_init will be called
      to reconfigure i2c controller. If sda_hold_time is zero, the chipset
      default hold time will be used, that will be too short for some
      platforms. Therefore, to have a better tolerance, the DW_IC_SDA_HOLD
      value should be kept by sda_hold_time.
