       "Specifics:
      
         - Update the help text of INT3403 Thermal driver, which was not
           friendly to users.  From Zhang Rui.
      
         - The "type" sysfs attribute of x86_pkg_temp_thermal registered
           thermal zones includes an instance number, which makes the
           thermal-to-hwmon bridge fails to group them all in a single hwmon
           device.  Fixed by Jean Delvare.
      
         - The hwmon device registered by x86_pkg_temp_thermal driver is
           redundant because the temperature value reported by
           x86_pkg_temp_thermal is already reported by the coretemp driver.
           Fixed by Jean Delvare.
      
         - Fix a problem that the cooling device can not be updated properly
           if it is initialized at max cooling state.  From Ni Wade.
      
         - Fix a problem that OF registered thermal zones are running without
           thermal governors.  From Zhang Rui.
      
         - Commit beeb5a1e ("thermal: rcar-thermal: Enable driver
           compilation with COMPILE_TEST") broke build on archs wihout io
           memory.  Thus make it depend on HAS_IOMEM to bypass build failures.

      Pull workqueue fix from Tejun Heo:
       "This pull request contains a workqueue usage fix for firewire.
      
        For quite a long time now, workqueue only treats two work items
        identical iff both their addresses and callbacks match.  This is to
        avoid introducing false dependency through the work item being
        recycled while being executed.  This changes non-reentrancy guarantee
        for the users of PREPARE[_DELAYED]_WORK() - if the function changes,
        reentrancy isn't guaranteed against the previous instance.  Firewire
        depended on such nonreentrancy guarantee.
      
        This is fixed by doing the work item multiplexing from firewire proper
        while keeping the work function unchanged"

      Pull ACPI and power management fixes from Rafael Wysocki:
      
       - ACPI tables in some BIOSes list device resources with size equal to
         0, which doesn't make sense, so we should ignore them, but instead we
         try to use them and mangle things completely.  Fix from Zhang Rui.
      
       - Several models of Samsung laptops accumulate EC events when they are
         in sleep states which leads to EC buffer overflows that prevent new
         events from being signaled after system resume or reboot.  This has
         been affecting many users for quite a while and may be addressed by
         clearing the EC buffer during system resume and system startup on
         those machines.  From Kieran Clancy.
      
       - If the ACPI sleep control and status registers are not present (which
         happens if the Hardware Reduced ACPI mode bit is set in the ACPI
         tables, but also may result from BIOS bugs), we should not try to use
         ACPI to power off the system and ACPI S5 should not be listed as
         supported.  Fix from Aubrey Li.
      
       - There's a race condition in cpufreq_get() that leads to a kernel
         crash if that function is called at a wrong time.  Fix from Aaron
         Plattner.
      
       - cpufreq policy objects have to be initialized entirely before they
         are first accessed by their users which isn't the case currently and
         that potentially leads to various kinds of breakage that is difficult
         to debug.  Fix from Viresh Kumar.
      
       - Locking is missing in __cpufreq_add_dev() which leads to a race
         condition that may trigger a kernel crash.  Fix from Viresh Kumar.

      x86: fix compile error due to X86_TRAP_NMI use in asm files · b01d4e68
      Linus Torvalds authored
      It's an enum, not a #define, you can't use it in asm files.
      
      Introduced in commit 5fa10196 ("x86: Ignore NMIs that come in during
      early boot"), and sadly I didn't compile-test things like I should have
      before pushing out.
      
      My weak excuse is that the x86 tree generally doesn't introduce stupid
      things like this (and the ARM pull afterwards doesn't cause me to do a
      compile-test either, since I don't cross-compile).

      Pull tracing fix from Steven Rostedt:
       "In the past, I've had lots of reports about trace events not working.
        Developers would say they put a trace_printk() before and after the
        trace event but when they enable it (and the trace event said it was
        enabled) they would see the trace_printks but not the trace event.
      
        I was not able to reproduce this, but that's because I wasn't looking
        at the right location.  Recently, another bug came up that showed the
        issue.
      
        If your kernel supports signed modules but allows for non-signed
        modules to be loaded, then when one is, the kernel will silently set
        the MODULE_FORCED taint on the module.  Although, this taint happens
        without the need for insmod --force or anything of the kind, it labels
        the module with that taint anyway.
      
        If this tainted module has tracepoints, the tracepoints will be
        ignored because of the MODULE_FORCED taint.  But no error message will
        be displayed.  Worse yet, the event infrastructure will still be
        created letting users enable the trace event represented by the
        tracepoint, although that event will never actually be enabled.  This
        is because the tracepoint infrastructure allows for non-existing
        tracepoints to be enabled for new modules to arrive and have their
        tracepoints set.
      
        Although there are several things wrong with the above, this change
        only addresses the creation of the trace event files for tracepoints
        that are not created when a module is loaded and is tainted.  This
        change will print an error message about the module being tainted and
        not the trace events will not be created, and it does not create the
        trace event infrastructure"

      x86: Ignore NMIs that come in during early boot · 5fa10196
      H. Peter Anvin authored
      Don Zickus reports:
      
      A customer generated an external NMI using their iLO to test kdump
      worked.  Unfortunately, the machine hung.  Disabling the nmi_watchdog
      made things work.
      
      I speculated the external NMI fired, caused the machine to panic (as
      expected) and the perf NMI from the watchdog came in and was latched.
      My guess was this somehow caused the hang.

      It appears that the latched NMI stays latched until the early page
      table generation on 64 bits, which causes exceptions to happen which
      end in IRET, which re-enable NMI.  Therefore, ignore NMIs that come in
      during early execution, until we have proper exception handling.

      ARM: 7992/1: boot: compressed: ignore bswapsdi2.S · 38e0b088
      Mark Rutland authored
      Commit 017f161a (ARM: 7877/1: use built-in byte swap function) added
      bswapsdi2.{o,S} to arch/arm/boot/compressed/Makefile, but didn't update
      the .gitignore. Thus after a a build git status shows bswapsdi2.S as a
      new file, which is a little annoying.
      
      This patch updates arch/arm/boot/compressed/.gitignore to ignore
      bswapsdi2.S, as we already do for ashldi3.S and others.

      ARM: 7991/1: sa1100: fix compile problem on Collie · 052450fd
      Linus Walleij authored
      Due to a problem in the MFD Kconfig it was not possible to
      compile the UCB battery driver for the Collie SA1100 system,
      in turn making it impossible to compile in the battery driver.
      (See patch "mfd: include all drivers in subsystem menu".)
      
      After fixing the MFD Kconfig (separate patch) a compile error
      appears in the Collie battery driver due to the <mach/collie.h>
      implicitly requiring <mach/hardware.h> through <linux/gpio.h>
      via <mach/gpio.h> prior to commit
      40ca061b "ARM: 7841/1: sa1100: remove complex GPIO interface".
      
      Fix this up by including the required header into
      <mach/collie.h>.

      ARM: fix noMMU kallsyms symbol filtering · 006fa259
      Russell King authored
      With noMMU, CONFIG_PAGE_OFFSET was not being set correctly.  As there's
      no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases.  This
      commit makes that explicit.
      
      Since we do this, we don't need to mess around in asm/memory.h with
      ifdefs to sort this out, so let's get rid of that, and there's no point
      offering the "Memory split" option for noMMU as that's meaningless
      there.

      usb: Make DELAY_INIT quirk wait 100ms between Get Configuration requests · d86db25e
      Julius Werner authored
      The DELAY_INIT quirk only reduces the frequency of enumeration failures
      with the Logitech HD Pro C920 and C930e webcams, but does not quite
      eliminate them. We have found that adding a delay of 100ms between the
      first and second Get Configuration request makes the device enumerate
      perfectly reliable even after several weeks of extensive testing. The
      reasons for that are anyone's guess, but since the DELAY_INIT quirk
      already delays enumeration by a whole second, wating for another 10th of
      that isn't really a big deal for the one other device that uses it, and
      it will resolve the problems with these webcams.

      usb: Add device quirk for Logitech HD Pro Webcams C920 and C930e · e0429362
      Julius Werner authored
      We've encountered a rare issue when enumerating two Logitech webcams
      after a reboot that doesn't power cycle the USB ports. They are spewing
      random data (possibly some leftover UVC buffers) on the second
      (full-sized) Get Configuration request of the enumeration phase. Since
      the data is random this can potentially cause all kinds of odd behavior,
      and since it occasionally happens multiple times (after the kernel
      issues another reset due to the garbled configuration descriptor), it is
      not always recoverable. Set the USB_DELAY_INIT quirk that seems to work
      around the issue.

      dm space map metadata: fix refcount decrement below 0 which caused corruption · cebc2de4
      Joe Thornber authored
      This has been a relatively long-standing issue that wasn't nailed down
      until Teng-Feng Yang's meticulous bug report to dm-devel on 3/7/2014,
      see: http://www.redhat.com/archives/dm-devel/2014-March/msg00021.html
      
      From that report:
        "When decreasing the reference count of a metadata block with its
        reference count equals 3, we will call dm_btree_remove() to remove
        this enrty from the B+tree which keeps the reference count info in
        metadata device.
      
        The B+tree will try to rebalance the entry of the child nodes in each
        node it traversed, and the rebalance process contains the following
        steps.
      
        (1) Finding the corresponding children in current node (shadow_current(s))
        (2) Shadow the children block (issue BOP_INC)
        (3) redistribute keys among children, and free children if necessary (issue BOP_DEC)
      
        Since the update of a metadata block's reference count could be
        recursive, we will stash these reference count update operations in
        smm->uncommitted and then process them in a FILO fashion.
      
        The problem is that step(3) could free the children which is created
        in step(2), so the BOP_DEC issued in step(3) will be carried out
        before the BOP_INC issued in step(2) since these BOPs will be
        processed in FILO fashion. Once the BOP_DEC from step(3) tries to
        decrease the reference count of newly shadow block, it will report
        failure for its reference equals 0 before decreasing. It looks like we
        can solve this issue by processing these BOPs in a FIFO fashion
        instead of FILO."
      
      Commit 5b564d80 ("dm space map: disallow decrementing a reference count
      below zero") changed the code to report an error for this temporary
      refcount decrement below zero.  So what was previously a harmless
      invalid refcount became a hard failure due to the new error path:
      
       device-mapper: space map common: unable to decrement a reference count below 0
       device-mapper: thin: 253:6: dm_thin_insert_block() failed: error = -22
       device-mapper: thin: 253:6: switching pool to read-only mode
      
      This bug is in dm persistent-data code that is common to the DM thin and
      cache targets.  So any users of those targets should apply this fix.
      
      Fix this by applying recursive space map operations in FIFO order rather
      than FILO.

      firewire: don't use PREPARE_DELAYED_WORK · 70044d71
      Tejun Heo authored
      PREPARE_[DELAYED_]WORK() are being phased out.  They have few users
      and a nasty surprise in terms of reentrancy guarantee as workqueue
      considers work items to be different if they don't have the same work
      function.
      
      firewire core-device and sbp2 have been been multiplexing work items
      with multiple work functions.  Introduce fw_device_workfn() and
      sbp2_lu_workfn() which invoke fw_device->workfn and
      sbp2_logical_unit->workfn respectively and always use the two
      functions as the work functions and update the users to set the
      ->workfn fields instead of overriding work functions using
      PREPARE_DELAYED_WORK().
      
      This fixes a variety of possible regressions since a2c1c57b
      "workqueue: consider work function when searching for busy work items"
      due to which fw_workqueue lost its required non-reentrancy property.
