      dma-debug: introduce debug_dma_assert_idle() · 0abdd7a8
      由 Dan Williams 提交于 
      Record actively mapped pages and provide an api for asserting a given
page is dma inactive before execution proceeds.  Placing
debug_dma_assert_idle() in cow_user_page() flagged the violation of the
dma-api in the NET_DMA implementation (see commit 77873803 "net_dma:
mark broken").

The implementation includes the capability to count, in a limited way,
repeat mappings of the same page that occur without an intervening
unmap.  This 'overlap' counter is limited to the few bits of tag space
in a radix tree.  This mechanism is added to mitigate false negative
cases where, for example, a page is dma mapped twice and
debug_dma_assert_idle() is called after the page is un-mapped once.

      由 Linus Torvalds 提交于 
      Pull sound updates from Takashi Iwai:
 "It was holiday season, so no wonder that there are little changes in
  framework level, although diffstat shows quite many changes spreaded
  over sound/* directories.  Most of changes are cleanups, code
  refactoring and fixes.

  Some highlights:
   - Removal of OSS sleep_on usages by Arnd
   - Simplified memalloc helper codes, drop obsoleted features; now it's
     built into PCM driver instead of an individual module
   - Warn if PCM buffer preallocation fails, which will show page
     allocation issues more clearly
   - Compress offload API updates for sample rates by Vinod
   - PCM glitch workaround on ctxfi emu20k1 by Sarah
   - Drop cs46xx DSP blobs, using firmware loader now
   - USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and
     Focusrite Saffire 6

  HD-audio specifics:
   - Standardize Kconfigs of HD-audio codec drivers; now "make
     localmodconfig" recognizes configs properly (finally!)
   - Parallel PM implementation by Mengdong
   - BayleyBay/ValleyView2 board fixups
   - Broadwell audio support
   - Runtime PM improvement (PantherPoint, etc)
   - Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell
     AiO click noise fixes, Dell headset mic fixes, etc
   - Automatic bind with HDMI codec parser without generic parser
   - More AD codec fixes (since 3.12 regression) including the automatic
     stereo mix support
   - Common Thinkpad ACPI helper for Realtek and Conexant codecs

  ASoC specifics:
   - Update to the generic DMA code to support deferred probe and
     managed resources
   - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
     and Analog Devices AXI I2S and S/PDIF controller IPs
   - Device tree support for the simple card, max98090 and cs42l52
   - Conversion of the Samsung drivers to native dmaengine, making them
     multiplatform compatible and hopefully helping keep them more
     modern and up to date.
   - More regmap conversions, including a very welcome one for twl6040
     from Peter Ujfalusi
   - A big overhaul of the DaVinci drivers also from Peter Ujfalusi
   - Lots of DMA updates from Lars-Peter
   - Improvements to the constraints handling code from Lars-Peter
   - A very helpful conversion of the TWL4030 driver to regmap from Peter
   - A new driver for the Freescale ESAI controller from Nicolin Chen
   - Conversion of some of the drivers to use params_width()
   - Extensions to DPCM for use with compressed audio from Liam"

 "This has been queued and tested for a while.  Lots of action here,

  Qualcomm driver as it is used in such a huge subset of mobile handsets
  out there, and these platforms in general need better upstream support

   - New driver for the Qualcomm TLMM pin controller and its msm8x74
     subdriver.

   - New driver for the Broadcom Capri BCM281xx SoC.

   - New subdriver for the imx25 pin controller.

   - New subdriver for the Tegra124 pin controller.

   - Lock GPIO lines as IRQs for select combined pin control and GPIO
     drivers for baytrail and sirf.

   - Some semi-big refactorings and extenstions to the sirf driver.

   - Lots of patching, cleanup and fixing in the Renesas "PFC" driver
     and associated subdrivers as usual.  It is settling down a little
     bit now it seems.

      Merge tag 'gpio-v3.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio · 8e509660
      由 Linus Torvalds 提交于 
      Pull GPIO tree bulk changes from Linus Walleij:
 "A big set this merge window, as we have much going on in this
  subsystem.  The changes to other subsystems (notably a slew of ARM
  machines as I am doing away with their custom APIs) have all been
  ACKed to the extent possible.

  Major changes this time:

   - Some core improvements and cleanups to the new GPIO descriptor API.
     This seems to be working now so we can start the exodus to this
     API, moving gradually away from the global GPIO numberspace.

   - Incremental improvements to the ACPI GPIO core, and move the few
     GPIO ACPI clients we have to the GPIO descriptor API right *now*
     before we go any further.  We actually managed to contain this
     *before* we started to litter the kernel with yet another hackish
     global numberspace for the ACPI GPIOs, which is a big win.

   - The RFkill GPIO driver and all platforms using it have been
     migrated to use the GPIO descriptors rather than fixed number
     assignments.  Tegra machine has been migrated as part of this.

   - New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.  Those
     should be really good examples of how I expect a nice GPIO driver
     to look these days.

   - Do away with custom GPIO implementations on a major part of the ARM
     machines: ks8695, lpc32xx, mv78xx0.  Make a first step towards the
     same in the horribly convoluted Samsung S3C include forest.  We
     expect to continue to clean this up as we move forward.

   - Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and
     lynxpoint.

     This makes the GPIOlib core aware that a certain GPIO line is used
     for IRQs and can then enforce some semantics such as disallowing a
     GPIO line marked as in use for IRQ to be switched to output mode.

   - Drop all use of irq_set_chip_and_handler_name().  The name provided
     in these cases were just unhelpful tags like "mux" or "demux".

   - Extend the MCP23s08 driver to handle interrupts.

   - Minor incremental improvements for rcar, lynxpoint, em 74x164 and
     msm drivers.

   - Some non-urgent bug fixes here and there, duplicate #includes and
     that usual kind of cleanups"

Fix up broken Kconfig file manually to make this all compile.
