      Linus Torvalds authored
      Pull sbp-2 (firewire) target mode support from Nicholas Bellinger:
       "The FireWire SBP-2 Target is a driver for using an IEEE-1394
        connection as a SCSI transport.  This module uses the SCSI Target
        framework to expose LUNs to other machines attached to a FireWire bus,
        in effect acting as a FireWire hard disk similar to FireWire Target
        Disk mode on many Apple computers.
      
        Also included are the two drivers/firewire/ patches required by
        sbp-target to access fw_request fabric speed needed for mgt_agent
        TCODE_WRITE_BLOCK_REQUEST ops, and exporting fw_card kref logic used
        when creating/destroying active session references to individual
        endpoints.
      
        A credit goes to Chris in being able to get this code up and running
        so quickly w/o any target core changes, and special thanks goes out to
        Stefan Richter + Clemens Ladisch + Andy Grover for their help in
        getting this driver ready for mainline.  Also, one of Chris's goals
        was to be able to connect sbp-target to a PowerPC based MacOS-X based
        client, that he accomplished along the way in this obligatory
        screenshot:

      Merge tag 'sound-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound · 2e341ca6
      Linus Torvalds authored
      Pull sound updates from Takashi Iwai:
       "This is the first big chunk for 3.5 merges of sound stuff.
      
        There are a few big changes in different areas.  First off, the
        streaming logic of USB-audio endpoints has been largely rewritten for
        the better support of "implicit feedback".  If anything about USB got
        broken, this change has to be checked.
      
        For HD-audio, the resume procedure was changed; instead of delaying
        the resume of the hardware until the first use, now waking up
        immediately at resume.  This is for buggy BIOS.
      
        For ASoC, dynamic PCM support and the improved support for digital
        links between off-SoC devices are major framework changes.
      
        Some highlights are below:
      
        * HD-audio
         - Avoid accesses of invalid pin-control bits that may stall the codec
         - V-ref setup cleanups
         - Fix the races in power-saving code
         - Fix the races in codec cache hashes and connection lists
         - Split some common codes for BIOS auto-parser to hda_auto_parser.c
         - Changed the PM resume code to wake up immediately for buggy BIOS
         - Creative SoundCore3D support
         - Add Conexant CX20751/2/3/4 codec support
      
        * ASoC
         - Dynamic PCM support, allowing support for SoCs with internal
           routing through components with tight sequencing and formatting
           constraints within their internal paths or where there are multiple
           components connected with CPU managed DMA controllers inside the
           SoC.
         - Greatly improved support for direct digital links between off-SoC
           devices, providing a much simpler way of connecting things like
           digital basebands to CODECs.
         - Much more fine grained and robust locking, cleaning up some of the
           confusion that crept in with multi-component.
         - CPU support for nVidia Tegra 30 I2S and audio hub controllers and
           ST-Ericsson MSP I2S controolers
         - New CODEC drivers for Cirrus CS42L52, LAPIS Semiconductor ML26124,
           Texas Instruments LM49453.
         - Some regmap changes needed by the Tegra I2S driver.
         - mc13783 audio support.
      
        * Misc
         - Rewrite with module_pci_driver()
         - Xonar DGX support for snd-oxygen
         - Improvement of packet handling in snd-firewire driver
         - New USB-endpoint streaming logic
         - Enhanced M-audio FTU quirks and relevant cleanups
         - Increment the support of OSS devices to 256
         - snd-aloop accuracy improvement
      
        There are a few more pending changes for 3.5, but they will be sent
        slightly later as partly depending on the changes of DRM."
      
      Fix up conflicts in regmap (due to duplicate patches, with some further
      updates then having already come in from the regmap tree).  Also some
      fairly trivial context conflicts in the imx and mcx soc drivers.

      Pull exception table generation updates from Ingo Molnar:
       "The biggest change here is to allow the build-time sorting of the
        exception table, to speed up booting.  This is achieved by the
        architecture enabling BUILDTIME_EXTABLE_SORT.  This option is enabled
        for x86 and MIPS currently.
      
        On x86 a number of fixes and changes were needed to allow build-time
        sorting of the exception table, in particular a relocation invariant
        exception table format was needed.  This required the abstracting out
        of exception table protocol and the removal of 20 years of accumulated
        assumptions about the x86 exception table format.
      
        While at it, this tree also cleans up various other aspects of
        exception handling, such as early(er) exception handling for
        rdmsr_safe() et al.
      
        All in one, as the result of these changes the x86 exception code is
        now pretty nice and modern.  As an added bonus any regressions in this
        code will be early and violent crashes, so if you see any of those,
        you'll know whom to blame!"
      
      Fix up trivial conflicts in arch/{mips,x86}/Kconfig files due to nearby
      modifications of other core architecture options.

      Jiri Olsa authored
      This reverts commit cb04ff9a ("sched, perf: Use a single
      callback into the scheduler").
      
      Before this change was introduced, the process switch worked
      like this (wrt. to perf event schedule):
      
           schedule (prev, next)
             - schedule out all perf events for prev
             - switch to next
             - schedule in all perf events for current (next)
      
      After the commit, the process switch looks like:
      
           schedule (prev, next)
             - schedule out all perf events for prev
             - schedule in all perf events for (next)
             - switch to next
      
      The problem is, that after we schedule perf events in, the pmu
      is enabled and we can receive events even before we make the
      switch to next - so "current" still being prev process (event
      SAMPLE data are filled based on the value of the "current"
      process).
      
      Thats exactly what we see for test__PERF_RECORD test. We receive
      SAMPLES with PID of the process that our tracee is scheduled
      from.
      
      Discussed with Peter Zijlstra:
      
       > Bah!, yeah I guess reverting is the right thing for now. Sad
       > though.
       >
       > So by having the two hooks we have a black-spot between them
       > where we receive no events at all, this black-spot covers the
       > hand-over of current and we thus don't receive the 'wrong'

      Michael Olbrich authored
      i6300esb is on of the watchdogs QEMU can emulate. It is also available
      when emulating ARM. The driver works without problems and is quite
      useful to test userspace dealing with /dev/watchdog.

      watchdog: Use module_pci_driver · 5ce9c371
      Wim Van Sebroeck authored
      This patch converts the PCI watchdog drivers so that they use the
      module_pci_driver() macro. This makes the code smaller and simpler.

      watchdog: sch311x_wdt.c: Remove RESGEN · 8f90a3ae
      Dave Mueller authored
      The SCH311x chip contains 2 watchdogs. One is the watchdog programmable
      by the runtime register at address 0x65-0x68, the other is the watchdog
      inside the power on reset generator. This second watchdog has a fixed
      timeout value of ~1.6 seconds and is configurable only by the RESGEN
      register.
      
      The BIOS normally takes care of the RESGEN watchdog and disables it (at
      least) before the OS is booted.
      
      Unfortunately the sch311x_wdt driver clears bit 0 of the RESGEN register
      which has the effect that at the latest 1.6 seconds later, a POR is
      triggered.
      
      The attached patch fixes this problem by completely removing any
      reference to the RESGEN watchdog from the sch311x_wdt driver.
