8dd2bc0f8e cxl/mem: Add the cxl_mem driver
At this point the subsystem can enumerate all CXL ports (CXL.mem decode
resources in upstream switch ports and host bridges) in a system. The
last mile is connecting those ports to endpoints.

The cxl_mem driver connects an endpoint device to the platform CXL.mem
protoctol decode-topology. At ->probe() time it walks its
device-topology-ancestry and adds a CXL Port object at every Upstream
Port hop until it gets to CXL root. The CXL root object is only present
after a platform firmware driver registers platform CXL resources. For
ACPI based platform this is managed by the ACPI0017 device and the
cxl_acpi driver.

The ports are registered such that disabling a given port automatically
unregisters all descendant ports, and the chain can only be registered
after the root is established.

Given ACPI device scanning may run asynchronously compared to PCI device
scanning the root driver is tasked with rescanning the bus after the
root successfully probes.

Conversely if any ports in a chain between the root and an endpoint
becomes disconnected it subsequently triggers the endpoint to
unregister. Given lock depenedencies the endpoint unregistration happens
in a workqueue asynchronously. If userspace cares about synchronizing
delayed work after port events the /sys/bus/cxl/flush attribute is
available for that purpose.

cf1f6877b0 cxl/memdev: Add numa_node attribute
While CXL memory targets will have their own memory target node,
individual memory devices may be affinitized like other PCI devices.
Emit that attribute for memdevs.

bcc79ea343 cxl/pci: Emit device serial number
Per the CXL specification (8.1.12.2 Memory Device PCIe Capabilities and
Extended Capabilities) the Device Serial Number capability is mandatory.
Emit it for user tooling to identify devices.

It is reasonable to ask whether the attribute should be added to the
list of PCI sysfs device attributes. The PCI layer can optionally emit
it too, but the CXL subsystem is aiming to preserve its independence and
the possibility of CXL topologies with non-PCI devices in it. To date
that has only proven useful for the 'cxl_test' model, but as can be seen
with seen with ACPI0016 devices, sometimes all that is needed is a
platform firmware table to point to CXL Component Registers in MMIO
space to define a "CXL" device.

1018a5463a f2fs: introduce F2FS_IPU_HONOR_OPU_WRITE ipu policy
Once F2FS_IPU_FORCE policy is enabled in some cases:
a) f2fs forces to use F2FS_IPU_FORCE in a small-sized volume
b) user sets F2FS_IPU_FORCE policy via sysfs

Then we may fail to defragment file due to IPU policy check, it doesn't
make sense, let's introduce a new IPU policy to allow OPU during file
defragmentation.

In small-sized volume, let's enable F2FS_IPU_HONOR_OPU_WRITE policy
by default.

ab28e94419 topology/sysfs: Add PPIN in sysfs under cpu topology
PPIN is the Protected Processor Identification Number.
This is used to identify the socket as a Field Replaceable Unit (FRU).

Existing code only displays this when reporting errors. But this makes
it inconvenient for large clusters to use it for its intended purpose
of inventory control.

Add ppin to /sys/devices/system/cpu/cpu*/topology to make what
is already available using RDMSR more easily accessible. Make
the file read only for root in case there are still people
concerned about making a unique system "serial number" available.

539fec78ed vdpa: add driver_override support
`driver_override` allows to control which of the vDPA bus drivers
binds to a vDPA device.

If `driver_override` is not set, the previous behaviour is followed:
devices use the first vDPA bus driver loaded (unless auto binding
is disabled).

Tested on Fedora 34 with driverctl(8):
  $ modprobe virtio-vdpa
  $ modprobe vhost-vdpa
  $ modprobe vdpa-sim-net

  $ vdpa dev add mgmtdev vdpasim_net name dev1

  # dev1 is attached to the first vDPA bus driver loaded
  $ driverctl -b vdpa list-devices
    dev1 virtio_vdpa

  $ driverctl -b vdpa set-override dev1 vhost_vdpa

  $ driverctl -b vdpa list-devices
    dev1 vhost_vdpa [*]

  Note: driverctl(8) integrates with udev so the binding is
  preserved.

 "In this cycle, tail-packing data inline for compressed files is now

  In addition, in order to show supported kernel features and control
  sync decompression strategy, new sysfs nodes are introduced in this

2nd set of new device support etc for IIO in the 5.17 cycle.

A small additional set of things that just missed the previous
pull request and have mostly been through plenty of review before the
holiday period began (or are trivial).  I've not taken some other series
on the list to allow for more eyes after the holiday period.

New device support
* adi,admv1013
  - New driver for this wideband microwave upconverter including dt-bindings
    and some device specific ABI due to the need to describe phase calibrations
    of a differential channel on both i and q phases. Previously we could
    do differential or i/q but not both on the same channel. The driver
    ABI uses a workaround for core support which will do until we know if
    this is a common requirement for which a more generic solution is
    needed.

MAINTAINERS:
* Add Haibo Chen as a maintainer for various NXP SoC ADCs.

Minor cleanup:
* sunrise_co2
  - Make sure an uninitialized value isn't used to set *val in read_raw().
    Not a real bug, but a compiler or reviewer can't tell that based
    on what they can see locally.
