939b83fb03 CRISv32: Add GPIO driver to the default configs
Fix a number of small issues visible when GPIO is enabled:

- Correct missing default for !ETRAXFS in Kconfig
- Remove information on number of bits for some Kconfigs
  related to the GPIO, they are different in ETRAX FS and ARTPEC-3
- Fix compile warning in ARTPEC-3 GPIO driver

4eae50143b Revert "NFS: Make close(2) asynchronous when closing NFS O_DIRECT files"
This reverts commit f895c53f8a.

This commit causes a NFSv4 regression in that close()+unlink() can end
up failing. The reason is that we no longer have a guarantee that the
CLOSE has completed on the server, meaning that the subsequent call to
REMOVE may fail with NFS4ERR_FILE_OPEN if the server implements Windows
unlink() semantics.

Pull sound updates from Takashi Iwai:
 "There are little changes in core part, but lots of development are
  found in drivers, especially ASoC.  The diffstat shows regmap-related
  changes for a slight API additions / changes, and that's all.

  Looking at the code size statistics, the most significant addition is
  for Intel Skylake.  (Note that SKL support is still underway, the
  codec driver is missing.) Also STI controller driver is a major
  addition as well as a few new codec drivers.

  In HD-audio side, there are fewer changes than the past.  The
  noticeable change is the support of ELD notification from i915
  graphics driver.  Thus this pull request carries a few changes in
  drm/i915.

  Other than that, USB-audio got a rewrite of runtime PM code.  It was
  initiated by lockdep warning, but resulted in a good cleanup in the
  end.

  Below are the highlights:

  Common:
   - Factoring out of AC'97 reset code from ASoC into the core helper
   - A few regmap API extensions (in case it's not pulled yet)

  ASoC:
   - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
     RT298 and ST STI controllers
   - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
     RT5650
   - Initial driver support for Intel Skylake devices
   - Lots of rsnd cleanup and enhancements
   - A few DAPM fixes and cleanups
   - A large number of cleanups in various drivers (conversion and
     standardized to regmap, component) mostly by Lars-Peter and Axel

  HD-audio:
   - Extended HD-audio core for Intel Skylake controller support
   - Quirks for Dell headsets, Alienware 15
   - Clean up of pin-based quirk tables for Realtek codecs
   - ELD notifier implenetation for Intel HDMI/DP

  USB-audio:
   - Refactor runtime PM code to make lockdep happier"

  idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
  the sorting be a true sort, not this mismash.

   - Power down support for the Qualcomm driver.

   - Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
     in IRQ handlers to play nice with the realtime patch set.

   - Rework and new modes handling for Qualcomm SPMI-MPP.

   - Pinconf power source config for SH PFC.

   - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
     ProXtream2 and PH1-LD6b SoC pin control support.

   - Reverse-egineered the S/PDIF settings for the Allwinner sun4i
     driver.

   - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs

   - A new Freescale i.mx6ul subdriver.

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.3 kernel cycle.

  There is quite a lot going on in the GPIO subsystem this merge window,
  so the main matter is decribed below.

  The hits in other subsystems when making the GPIO flags optional are
  all ACKed by their respective subsystem maintainers.

  Core changes:

   - Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
     of the descriptor calls that did not use the flags argument on the
     end.  This was around for too long and eventually Uwe Kleine-König
     took the time to clean it out and the last users are removed along
     with the macros in this tag.  In several cases the use of flags
     simplifies the code.  For this reason we have (ACKed) patches
     hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
     nail with removing the macros.

   - Add a fat document describing how much ready-made GPIO stuff we
     have i the kernel to discourage people from reinventing a square
     wheel in userspace, as so often happens.

   - Create a separate lockdep class for each instance of a GPIO IRQ
     chip instead of using one class for all chips, as the current code
     will not work with systems with several GPIO chips doing lockdep
     debugging.

   - Protect against driver unloading also when a GPIO line is only used
     as IRQ for the GPIOLIB_IRQCHIP helpers.

   - If the GPIO chip has no designated owner, assign the parent device
     driver owner as owner.

   - Consolidation of chained IRQ handler install/remove replacing all
     call sites where irq_set_handler_data() and
     irq_set_chained_handler() were done in succession with a combined
     call to irq_set_chained_handler_and_data().

     This series was created by Thomas Gleixner after the problem was
     observed by Russell King.

   - Tglx also made another series of patches switching
     __irq_set_handler_locked() for irq_set_handler_locked() which is
     way cleaner.

   - Tglx and Jiang Liu wrote a good bunch of patches to make use of
     irq_desc_get_xxx() accessors and avoid looking up irq_descs from
     IRQ numbers.  The goal is to get rid of the irq number from the
     handlers in the IRQ flow which is nice.

   - Rob Herring killed off the set_irq_flags() for all GPIO drivers.
     This was an ARM specific function that is replaced with the generic
     irq_modify_status() where special flags are actually needed.

   - When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
     if the pin controller isn't available.  Pretty logical, yet needed
     to be fixed.

   - If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
     back, then call these instead of the defaults provided by the
     GPIOLIB.

   - Fix an undocumented ABI hole: named GPIOs were not properly
     documented.

  Driver improvements:

   - Add get_direction() support to the generic GPIO driver, it's
     strange that we didn't have that before.

   - Make it possible to have input-only GPIO chips using the generic
     GPIO driver.

   - Clean out platform data support from the Emma Mobile (EM) driver

   - Finegrained runtime PM support for the RCAR driver.

   - Support r8a7795 (R-car H3) in the RCAR driver.

   - Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.

   - Some consolidation and new support in the MPC8xxx driver, we now
     support MPC5125.

   - Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
     spinlocks making it work better with the realime patches.

   - Interrupt support for the EXTRAXFS GPIO driver.

   - Make the ETRAXFS GPIO driver support also ARTPEC-3.

   - Interrupt and wakeup support for the BRCMSTB driver, also for
     wakeup from S5 cold boot.

   - Mask MXC IRQs during suspend.

   - Improve OMAP2 GPIO set_debounce() to work according to spec.

   - The VF610 driver handles IRQs properly.

  New drivers:

   - ZTE ZX GPIO driver"

04bdfa8ab5 arm/arm64: KVM: vgic: Move active state handling to flush_hwstate
We currently set the physical active state only when we *inject* a new
pending virtual interrupt, but this is actually not correct, because we
could have been preempted and run something else on the system that
resets the active state to clear.  This causes us to run the VM with the
timer set to fire, but without setting the physical active state.

The solution is to always check the LR configurations, and we if have a
mapped interrupt in the LR in either the pending or active state
(virtual), then set the physical active state.

22f66895e6 mac80211: protect non-HT BSS when HT TDLS traffic exists
HT TDLS traffic should be protected in a non-HT BSS to avoid
collisions. Therefore, when TDLS peers join/leave, check if
protection is (now) needed and set the ht_operation_mode of
the virtual interface according to the HT capabilities of the
TDLS peer(s).

This works because a non-HT BSS connection never sets (or
otherwise uses) the ht_operation_mode; it just means that
drivers must be aware that this field applies to all HT
traffic for this virtual interface, not just the traffic
within the BSS. Document that.

21adf76e90 Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

  - In some cases where perf_event.fork.{pid,tid} should be used we were instead
    using perf_event.comm.{pid,tid}, which is not a problem for for the 'pid'
    case, that sits in the same place in these union_perf_event members, but
    comm.tid sits where fork.ppid is, oops.

    These cases were considered as (potentially) problematic:

     - 'perf script' with !sample_id_all, i.e. only non old kernels without
        perf_event_attr.sample_id_all.

     - intel_pt could be affected when decoding without timestamps, as the exit
       event is only used to flush out data which anyway gets flushed at the
       end of the session.

     - intel_bts also uses the exit event to flush data which would probably not
       cause errors as it would get flushed at the end of the session instead.

    Fix it. (Adrian Hunter)

  - Due to relaxing the compiler checks for bison generated files, we missed
    updating one parse_events_add_pmu() caller when this function had its
    prototype changed, fix it. (Jiri Olsa)
