On s390 each PCI device has a user-defined ID (UID) exposed under
/sys/bus/pci/devices/<dev>/uid. This ID was designed to serve as the PCI
device's primary index and to match the device within Linux to the
device configured in the hypervisor. To serve as a primary identifier
the UID must be unique within the Linux instance, this is guaranteed by
the platform if and only if the UID Uniqueness Checking flag is set
within the CLP List PCI Functions response.
In this sense the UID serves an analogous function as the SMBIOS
instance number or ACPI index exposed as the "index" respectively
"acpi_index" device attributes and used by e.g. systemd to set interface
names. As s390 does not use and will likely never use ACPI nor SMBIOS
there is no conflict and we can just expose the UID under the "index"
attribute whenever UID Uniqueness Checking is active and get systemd's
interface naming support for free.

Add a capability, KVM_CAP_SGX_ATTRIBUTE, that can be used by userspace
to grant a VM access to a priveleged attribute, with args[0] holding a
file handle to a valid SGX attribute file.
The SGX subsystem restricts access to a subset of enclave attributes to
provide additional security for an uncompromised kernel, e.g. to prevent
malware from using the PROVISIONKEY to ensure its nodes are running
inside a geniune SGX enclave and/or to obtain a stable fingerprint.
To prevent userspace from circumventing such restrictions by running an
enclave in a VM, KVM restricts guest access to privileged attributes by
default.

KVM_CAP_PPC_MULTITCE is a capability, not an ioctl.
Therefore move it from section 4.97 to the new 8.31 (other capabilities).
To fill the gap, move KVM_X86_SET_MSR_FILTER (was 4.126) to
4.97, and shifted Xen-related ioctl (were 4.127 - 4.130) by
one place (4.126 - 4.129).
Also fixed minor typo in KVM_GET_MSR_INDEX_LIST ioctl description
(section 4.3).

Convert the ti,secure-proxy to yaml for better checks and documentation.
Differences being mostly in the examples:
- Dropped the example usage of mailbox client, it is better done in
tisci node definition.
- Switched reg usage for address-cells and size-cells 1 - aligned with
schema checks as well.
- included header in example for a buildable example.
While at this, lets make sure to support upto 100 rx threads even though
typically upto 1 threads is practically in use.
NOTE: The following checkpatch warning is generated since we do include the header
in the example, but this is a false positive warning.
WARNING: DT binding docs and includes should be a separate patch. See:

Add optional brcm,ccode-map property to support translation from ISO3166
country code to brcmfmac firmware country code and revision.
The country revision is needed because the RF parameters that provide
regulatory compliance are tweaked per platform/customer. So depending
on the RF path tight to the chip, certain country revision needs to be
specified. As such they could be seen as device specific calibration
data which is a good fit into device tree.

Similarly to pause statistics add stats for FEC.
The IEEE standard mandates two sets of counters:
- 30.5.1.1.17 aFECCorrectedBlocks
- 30.5.1.1.18 aFECUncorrectableBlocks
where block is a block of bits FEC operates on.
Each of these counters is defined per lane (PCS instance).
Multiple vendors provide number of corrected _bits_ rather
than/as well as blocks.
This set adds the 2 standard-based block counters and a extra
one for corrected bits.
Counters are exposed to user space via netlink in new attributes.
Each attribute carries an array of u64s, first element is
the total count, and the following ones are a per-lane break down.
Much like with pause stats the operation will not fail when driver
does not implement the get_fec_stats callback (nor can the driver
fail the operation by returning an error). If stats can't be
reported the relevant attributes will be empty.

The kernel now has a number of testing and debugging tools, and we've
seen a bit of confusion about what the differences between them are.
Add a basic documentation outlining the testing tools, when to use each,
and how they interact.
This is a pretty quick overview rather than the idealised "kernel
testing guide" that'd probably be optimal, but given the number of times
questions like "When do you use KUnit and when do you use Kselftest?"
are being asked, it seemed worth at least having something. Hopefully
this can form the basis for more detailed documentation later.

These correspond to the existing lpc_address, sirq, and sirq_polarity
sysfs attributes; the second element of aspeed,lpc-interrupts provides
a replacement for the deprecated aspeed,sirq-polarity-sense property.

This property ties SIRQ polarity to SCU register bits that don't
necessarily have any direct relationship to it; the only use of it was
removed in commit c82bf6e133d3 ("ARM: aspeed: g5: Do not set sirq
polarity").

Currently each packet inserted in eswitch is tagged with a internal
metadata to indicate source vport. Metadata tagging is not always
needed. Metadata insertion is needed for multi-port RoCE, failover
between representors and stacked devices. In many other cases,
metadata enablement is not needed.
Metadata insertion slows down the packet processing rate of the E-switch
when it is in switchdev mode.
Below table show performance gain with metadata disabled for VXLAN
offload rules in both SMFS and DMFS steering mode on ConnectX-5 device.
----------------------------------------------
| steering | metadata | pkt size | rx pps |
| mode | | | (million) |
----------------------------------------------
| smfs | disabled | 128Bytes | 42 |
----------------------------------------------
| smfs | enabled | 128Bytes | 36 |
----------------------------------------------
| dmfs | disabled | 128Bytes | 42 |
----------------------------------------------
| dmfs | enabled | 128Bytes | 36 |
----------------------------------------------
Hence, allow user to disable metadata using driver specific devlink
parameter. Metadata setting of the eswitch is applicable only for the
switchdev mode.
Example to show and disable metadata before changing eswitch mode:
$ devlink dev param show pci/0000:06:00.0 name esw_port_metadata
pci/0000:06:00.0:
name esw_port_metadata type driver-specific
values:
cmode runtime value true
$ devlink dev param set pci/0000:06:00.0 \
name esw_port_metadata value false cmode runtime
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev
