      Pull ARM SoC fixes from from Olof Johansson:
       "A collection of fixes for ARM platforms.  A little large due to us
        missing to do one last week, but there's nothing in particular here
        that is in itself large and scary.
      
        Mostly a handful of smaller fixes all over the place.  The majority is
        made up of fixes for OMAP, but there are a few for others as well.  In
        particular, there was a decision to rename a binding for the Broadcom
        pinctrl block that we need to go in before the final release since we
        then treat it as ABI"

      KEYS: Make the keyring cycle detector ignore other keyrings of the same name · 979e0d74
      David Howells authored
      This fixes CVE-2014-0102.
      
      The following command sequence produces an oops:
      
      	keyctl new_session
      	i=`keyctl newring _ses @s`
      	keyctl link @s $i
      
      The problem is that search_nested_keyrings() sees two keyrings that have
      matching type and description, so keyring_compare_object() returns true.
      s_n_k() then passes the key to the iterator function -
      keyring_detect_cycle_iterator() - which *should* check to see whether this is
      the keyring of interest, not just one with the same name.
      
      Because assoc_array_find() will return one and only one match, I assumed that
      the iterator function would only see an exact match or never be called - but
      the iterator isn't only called from assoc_array_find()...
      
      The oops looks something like this:
      
      	kernel BUG at /data/fs/linux-2.6-fscache/security/keys/keyring.c:1003!
      	invalid opcode: 0000 [#1] SMP
      	...
      	RIP: keyring_detect_cycle_iterator+0xe/0x1f
      	...
      	Call Trace:
      	  search_nested_keyrings+0x76/0x2aa
      	  __key_link_check_live_key+0x50/0x5f
      	  key_link+0x4e/0x85
      	  keyctl_keyring_link+0x60/0x81
      	  SyS_keyctl+0x65/0xe4
      	  tracesys+0xdd/0xe2
      
      The fix is to make keyring_detect_cycle_iterator() check that the key it
      has is the key it was actually looking for rather than calling BUG_ON().
      
      A testcase has been included in the keyutils testsuite for this:

      Pull thermal fixes from Zhang Rui:
       "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 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.

      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".

      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.

      This reverts commit 3804fad4.
      
      This commit, together with commit 247bf557
      "xhci 1.0: Limit arbitrarily-aligned scatter gather." were
      origially added to get xHCI 1.0 hosts and usb ethernet ax88179_178a devices
      working together with scatter gather. xHCI 1.0 hosts pose some requirement on how transfer
      buffers are aligned, setting this requirement for 1.0 hosts caused USB 3.0 mass
      storage devices to fail more frequently.
      
      USB 3.0 mass storage devices used to work before 3.14-rc1.  Theoretically,

      Mathias Nyman authored
      This reverts commit 247bf557.
      
      This commit, together with commit 3804fad4
      "USBNET: ax88179_178a: enable tso if usb host supports sg dma" were
      origially added to get xHCI 1.0 hosts and usb ethernet ax88179_178a devices
      working together with scatter gather. xHCI 1.0 hosts pose some requirement on how transfer
      buffers are aligned, setting this requirement for 1.0 hosts caused USB 3.0 mass
      storage devices to fail more frequently.
      
      USB 3.0 mass storage devices used to work before 3.14-rc1.  Theoretically,
      the TD fragment rules could have caused an occasional disk glitch.
      Now the devices *will* fail, instead of theoretically failing.

      The proper soluition is to implement the TD fragment rules required, but for now
      this patch needs to be reverted to get USB 3.0 mass storage devices working at the
      level they used to.

      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.

      libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8 (2BA30001) · b28a613e
      Michele Baldessari authored
      Via commit 87809942 "libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk
      for Seagate Momentus SpinPoint M8" we added a quirk for disks named
      "ST1000LM024 HN-M101MBB" with firmware revision "2AR10001".
      
      As reported on https://bugzilla.redhat.com/show_bug.cgi?id=1073901,
      we need to also add firmware revision 2BA30001 as it is broken as well.

      Vineet Gupta authored
      This fixes a subtle issue with cache flush which could potentially cause
      random userspace crashes because of stale icache lines.
      
      This error crept in when consolidating the cache flush code
