 "Three fixes for RISC-V:

   - Don't free and reuse memory containing the code that CPUs parked at
     boot reside in.

   - Fix rv64 build problems for ubsan and some modules by adding
     logical and arithmetic shift helpers for 128-bit values. These are
     from libgcc and are similar to what's present for ARM64.

   - Fix vDSO builds to clean up their own temporary files"

      A queue can't belong to multiple traffic classes. So, reject
any such configuration that results in overlapped queues for a
traffic class.

      cxgb4: fix Tx multi channel port rate limit · c856e2b6
      Rahul Lakkireddy authored 
      T6 can support 2 egress traffic management channels per port to
double the total number of traffic classes that can be configured.
In this configuration, if the class belongs to the other channel,
then all the queues must be bound again explicitly to the new class,
for the rate limit parameters on the other channel to take effect.

So, always explicitly bind all queues to the port rate limit traffic
class, regardless of the traffic management channel that it belongs
to. Also, only bind queues to port rate limit traffic class, if all
the queues don't already belong to an existing different traffic
class.

      Merge tag 'iio-for-5.6b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Second set of new device support, features and minor fixes for IIO in the 5.6 cycle

Just a small set this time.

As we are very near the merge window, I've rolled a few fixes in here
rather than adding noise just before release.  A short delay here will
do little harm.

New device support
* adis16480
  - Add support for adis16490. After earlier rework this is simple ID plus
    chip info.

Features
* kxcjk1013
  - mount matrix support.
* lsm_6dsx
  - mount matrix support.

Cleanups / minor or late breaking fixes
* ad7124
  - add support to ad-sigma-delta and use it in this driver to allow
    the the interrupt type to be IRQF_TRIGGER_LOW unlike most other devices
    using this framework.
* adis
  - use delay structure now available in SPI to handle transfer delays
  - introduce a timeouts structure to allow support of new devices
* ak8975
  - drop platform data support.  No one is using it and it adds complexity.
  - use device_get_match_data rather than open coding much the same thing.
* dht11
  - drop meaningless todo
* at91-samad2_adc
  - switch to dma_request_chan
* altas-sensor
  - add a helper function to compute number of channels.  Needed for new device
    support that is under review.
* bma400
  - add a lower bound check on scale.
* inv_mpu6050
  - add support for temperature data in the fifos for all chips.
  - support an odd situation where a board supports only interrupt triggering
    on both edges.
* st_lsm6dsx
  - check and handle potential error return.
* st_sensors
  - fix some values for the LSM9DS0 which is ever so slightly different from
    other devices using the same whoami value.
  - switch over to generic functions from dt ones, avoiding need for separate
    ACPI support.
* stm32-adc
  - switch to dma_request_chan
  - suppress an error print in deferred probe case.
* stm32-dac
  - drop private data structure element for reset controller as only used in
    probe.
  - reflect more cleanly that the reset controller is optional whilst ensuring
    that if is specified any errors are caught.
* stm32-dfsdm
  - switch to dma_request_chan
  - fix missing application of formatting to single conversions.
  - ensure the sampling rate is updated when the oversampling ratio is changed.

      riscv: Less inefficient gcc tishift helpers (and export their symbols) · fc585d4a
      Olof Johansson authored 
      The existing __lshrti3 was really inefficient, and the other two helpers
are also needed to compile some modules.

Add the missing versions, and export all of the symbols like arm64
already does.

This code is based on the assembly generated by libgcc builds.

This fixes a build break triggered by ubsan:

riscv64-unknown-linux-gnu-ld: lib/ubsan.o: in function `.L2':
ubsan.c:(.text.unlikely+0x38): undefined reference to `__ashlti3'
