       "Here are some bugfixes for the I2C subsystem.
      
        Kieran found a flaw in the recently renewed wake irq handling.  Mika
        handled a user bug report where the ACPI info turned out to be
        unusable.  I updated MAINTAINERS so that such bug reports will sooner
        get to the right people.  Geert pointed me to a problem of some i2c
        drivers regarding PM which I fixed"

      i2c: designware: Do not use parameters from ACPI on Dell Inspiron 7348 · 56d4b8a2
      Mika Westerberg authored
      ACPI SSCN/FMCN methods were originally added because then the platform can
      provide the most accurate HCNT/LCNT values to the driver. However, this
      seems not to be true for Dell Inspiron 7348 where using these causes the
      touchpad to fail in boot:
      
        i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
        i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
        i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
        i2c_designware INT3433:00: controller timed out
      
      The values received from ACPI are (in fast mode):
      
        HCNT: 72
        LCNT: 160
      
      this translates to following timings (input clock is 100MHz on Broadwell):
      
        tHIGH: 720 ns (spec min 600 ns)
        tLOW: 1600 ns (spec min 1300 ns)
        Bus period: 2920 ns (assuming 300 ns tf and tr)
        Bus speed: 342.5 kHz
      
      Both tHIGH and tLOW are within the I2C specification.
      
      The calculated values when ACPI parameters are not used are (in fast mode):
      
        HCNT: 87
        LCNT: 159
      
      which translates to:
      
        tHIGH: 870 ns (spec min 600 ns)
        tLOW: 1590 ns (spec min 1300 ns)
        Bus period 3060 ns (assuming 300 ns tf and tr)
        Bus speed 326.8 kHz
      
      These values are also within the I2C specification.
      
      Since both ACPI and calculated values meet the I2C specification timing
      requirements it is hard to say why the touchpad does not function properly
      with the ACPI values except that the bus speed is higher in this case (but
      still well below the max 400kHz).
      
      Solve this by adding DMI quirk to the driver that disables using ACPI
      parameters on this particulare machine.

        Dave is adding checks to make sure balance on current kernels ignores
        filters it doesn't understand.  The penalty for being wrong is just
        doing more work (not crashing etc), but it's a good fix"

        Specifics:
      
         - Fix a regression introduced by a recent ACPICA cleanup that
           uncovered a latent bug (Lv Zheng).
      
         - Fix a recent regression in the generic power domains framework that
           may cause it to violate PM QoS latency constraints in some cases
           (Ulf Hansson).
      
         - Fix an intel_pstate driver crash on the Knights Landing chips that
           do not update the MPERF counter as often as expected by the driver
           which may result in a divide by 0 (Srinivas Pandruvada)"

        I'm not sure it's worth putting in -fixes as I don't think we've seen
        it hit in the real world ever, I just found it using the virtio-gpu

      sh: add copy_user_page() alias for __copy_user() · 934ed25e
      Ross Zwisler authored
      copy_user_page() is needed by DAX.  Without this we get a compile error
      for DAX on SH:
      
        fs/dax.c:280:2: error: implicit declaration of function `copy_user_page' [-Werror=implicit-function-declaration]
          copy_user_page(vto, (void __force *)vfrom, vaddr, to);
            ^
      
      This was done with a random config that happened to include DAX support.
      
      This patch has only been compile tested.
