ARM SCMI updates for v5.6

1. Addition of multiple device support per protocol to enable use of
   some procotols by multiple kernel subsystems simultaneously and
   corresponding updates to the existing scmi drivers
2. Addition of trace events around the scmi transfer code to measure
   any delays and capture anomalies that can also be used during
   investigation of some platform firmware related issues

The SCMI transport layer communicates via mailboxes and shared memory with
firmware running on a microcontroller. It is platform specific how long it
takes to pass a SCMI message. The most sensitive requests are coming from
CPUFreq subsystem, which might be used by the scheduler.
Thus, there is a need to measure these delays and capture anomalies.
This change introduces trace events wrapped around transfer code.

According to Jim's suggestion a unique transfer_id is to distinguish
similar entries which might have the same message id, protocol id and
sequence. This is a case then there are some timeouts in transfers.

Adding trace events would help to measure the speed of the communication
channel. It can be also potentially used helpful during investigation
of some issues platforms which use different transport layer.

Update also MAINTAINERS file with information that the new trace events
are maintained.

The scmi bus now has support to match the driver with devices not only
based on their protocol id but also based on their device name if one is
available. This was added to cater the need to support multiple devices
and drivers for the same protocol.

Let us add the name "reset" to scmi_device_id table in the driver so
that in matches only with device with the same name and protocol id
SCMI_PROTOCOL_RESET.

added ever in future, we need to drop this hwmon driver entirely and
use the iio->hwmon bridge to access the sensors as hwmon devices if
needed.

The scmi bus now supports adding multiple devices per protocol,
and since scmi_protocol_init is called for each scmi device created,
we must avoid allocating protocol private data and initialising the
protocol itself if it is already initialised.

In order to achieve the same, we can simple replace the idr pointer
from protocol initialisation function to a dummy function.

Currently only one scmi device is created for each protocol enumerated.
However, there is requirement to make use of some procotols by multiple
kernel subsystems/frameworks. One such example is SCMI PERFORMANCE
protocol which can be used by both cpufreq and devfreq drivers.
Similarly, SENSOR protocol may be used by hwmon and iio subsystems,
and POWER protocol may be used by genpd and regulator drivers.

In order to achieve that, let us extend the scmi bus to match based
not only protocol id but also the scmi device name if one is available.

Pull rdma fixes from Doug Ledford:
 "A small collection of -rc fixes. Mostly. One API addition, but that's
  because we wanted to use it in a fix. There's also a bug fix that is
  going to render the 5.5 kernel's soft-RoCE driver incompatible with
  all soft-RoCE versions prior, but it's required to actually implement
  the protocol according to the RoCE spec and required in order for the
  soft-RoCE driver to be able to successfully work with actual RoCE
  hardware.

  Summary:

   - Update Steve Wise info

   - Fix for soft-RoCE crc calculations (will break back compatibility,
     but only with the soft-RoCE driver, which has had this bug since it
     was introduced and it is an on-the-wire bug, but will make
     soft-RoCE fully compatible with real RoCE hardware)

   - cma init fixup

   - counters oops fix

   - fix for mlx4 init/teardown sequence

   - fix for mkx5 steering rules

   - introduce a cleanup API, which isn't a fix, but we want to use it
     in the next fix

Pull ksys_mount() and ksys_dup() removal from Dominik Brodowski:
 "This small series replaces all in-kernel calls to the
  userspace-focused ksys_mount() and ksys_dup() with calls to
  kernel-centric functions:

  For each replacement of ksys_mount() with do_mount(), one needs to
  verify that the first and third parameter (char *dev_name, char *type)
  are strings allocated in kernelspace and that the fifth parameter
  (void *data) is either NULL or refers to a full page (only occurence
  in init/do_mounts.c::do_mount_root()). The second and fourth
  parameters (char *dir_name, unsigned long flags) are passed by
  ksys_mount() to do_mount() unchanged, and therefore do not require
  particular care.

  Moreover, instead of pretending to be userspace, the opening of
  /dev/console as stdin/stdout/stderr can be implemented using in-kernel
  functions as well. Thereby, ksys_dup() can be removed for good"

[ This doesn't get rid of the special "kernel init runs with KERNEL_DS"
  case, but it at least removes _some_ of the users of "treat kernel
  pointers as user pointers for our magical init sequence".

  One day we'll hopefully be rid of it all, and can initialize our
  init_thread addr_limit to USER_DS.    - Linus ]

Pull io_uring fixes from Jens Axboe:

 - A tweak to IOSQE_IO_LINK (also marked for stable) to allow links that
   don't sever if the result is < 0.

   This is mostly for linked timeouts, where if we ask for a pure
   timeout we always get -ETIME. This makes links useless for that case,
   hence allow a case where it works.

 - Five minor optimizations to fix and improve cases that regressed
   since v5.4.

 - An SQTHREAD locking fix.

 - A sendmsg/recvmsg iov assignment fix.

 - Net fix where read_iter/write_iter don't honor IOCB_NOWAIT, and
   subsequently ensuring that works for io_uring.

 - Fix a case where for an invalid opcode we might return -EBADF instead
   of -EINVAL, if the ->fd of that sqe was set to an invalid fd value.
