Jonathan writes:

Second set of new device support, features and cleanup for IIO in the 5.1 cycle.

There are a few late breaking fixes in here that weren't worth trying to
rush into 5.0 as they have been with us for quite a while.

New device support
* ad7476
  - add support for TI ADS786X parts that are compatible with this Analog
    Devices driver. Good to see some simple devices are so similar.
* Ingenic jz47xx SoC ADCs
  - new driver and bindings
* Plantower PMS7003 partical sensor
  - new driver and bindings including vendor prefix.
* TI DAC7612
  - new driver and bindings for this dual DAC.

New features
* ad7768-1
  - Sampling frequency control
* bmi160
  - Data ready trigger support, including open-drain dt binding.

Cleanup / minor fixes.
* Analog Device DACs
  - Fix some inconsistent licenses.  These are only ones where there were
    two different license marked in the same file, and hence were previously
    unclear.
* ads124s08
  - Spelling fix.
* adxl345
  - Parameter alignement tidy up.
* bmi160
  - SPDX
  - correct a note on the types of supported interrupts which was too strict.
  - use iio_pollfunc_store_time to grab an earlier timestamp.
  - use if (ret) instead of if (ret < 0) to be consistent whilst simplifying
    some handling where ret was effectively getting written to 0 even though
    it was always already 0.
* exynos_adc
  - Fix a null pointer dereference on unbind.
  - Fix number of channels on Exynos4x12 devices to be 4 rather than 8.
* lpc32xx-adc
  - Move DT bindings doc out of staging. Oops, I missed this one when
    moving the driver.
  - SPDX.
* npcm-adc
  - drop documentation of reset node as going to be done differently.
    It's a new driver this cycle so no need to support the previous
    binding going forwards.
* sps30
  - Fix an issue with a loop timeout test that meant it would never identify
    a timeout.
  - Mark deliberate switch fall throughs.

x86/mm: Make set_pmd_at() paravirt aware

set_pmd_at() calls native_set_pmd() unconditionally on x86. This was
fine as long as only huge page entries were written via set_pmd_at(),
as Xen pv guests don't support those.

Commit 2c91bd4a4e2e53 ("mm: speed up mremap by 20x on large regions")
introduced a usage of set_pmd_at() possible on pv guests, leading to
failures like:

   - A workaround for a Loongson 3 CPU bug is the biggest change, but
     still fairly straightforward. It adds extra memory barriers (sync
     instructions) around atomics to avoid a CPU bug that can break
     atomicity.

     would incorrectly reboot rather than waiting for the power down
     sequence to complete.

   - We have DT fixes for the Ingenic JZ4740 SoC & the JZ4780-based Ci20
     board, and a DT warning fix for the Nexsys4/MIPSfpga board.

   - The Cavium Octeon platform sees a further fix to the behaviour of
     the pcie_disable command line argument that was introduced in v3.3.

   - The VDSO, introduced in v4.4, sees build fixes for configurations
     of GCC that were built using the --with-fp-32= flag to specify a
     default 32-bit floating point ABI.

   - get_frame_info() sees a fix for configurations with
     CONFIG_KALLSYMS=n, for which it previously always returned an
     error.

   - If the MIPS Coherence Manager (CM) reports an error then we'll now
