Add documentation for In-Field Scan (IFS). This documentation
describes the basics of IFS, the loading IFS image, chunk
authentication, running scan and how to check result via sysfs.
The CORE_CAPABILITIES MSR enumerates whether IFS is supported.
The full github location for distributing the IFS images is
still being decided. So just a placeholder included for now
in the documentation.
Future CPUs will support more than one type of test. Plan for
that now by using a "_0" suffix on the ABI directory names.
Additional test types will use "_1", etc.

Implement sysfs interface to trigger ifs test for a specific cpu.
Additional interfaces related to checking the status of the
scan test and seeing the version of the loaded IFS binary
are also added.
The basic usage is as below.
- To start test, for example on cpu5:
echo 5 > /sys/devices/platform/intel_ifs/run_test
- To see the status of the last test
cat /sys/devices/platform/intel_ifs/status
- To see the version of the loaded scan binary
cat /sys/devices/platform/intel_ifs/image_version

In a core, the scan engine is shared between sibling cpus.
When a Scan test (for a particular core) is triggered by the user,
the scan chunks are executed on all the threads on the core using
stop_core_cpuslocked.
Scan may be aborted by some reasons. Scan test will be aborted in certain
circumstances such as when interrupt occurred or cpu does not have enough
power budget for scan. In this case, the kernel restart scan from the chunk
where it stopped. Scan will also be aborted when the test is failed. In
this case, the test is immediately stopped without retry.

The IFS image contains hashes that will be used to authenticate the ifs
test chunks. First, use WRMSR to copy the hashes and enumerate the number
of test chunks, chunk size and the maximum number of cores that can run
scan test simultaneously.
Next, use WRMSR to authenticate each and every scan test chunk which is
stored in the IFS image. The CPU will check if the test chunks match
the hashes, otherwise failure is indicated to system software. If the test
chunk is authenticated, it is automatically copied to secured memory.
Use schedule_work_on() to perform the hash copy and authentication. Note
this needs only be done on the first logical cpu of each socket.

Driver probe routine allocates structure to communicate status
and parameters between functions in the driver. Also call
load_ifs_binary() to load the scan image file.
There is a separate scan image file for each processor family,
model, stepping combination. This is read from the static path:
/lib/firmware/intel/ifs/{ff-mm-ss}.scan
Step 1 in loading is to generate the correct path and use
request_firmware_direct() to load into memory.
Subsequent patches will use the IFS MSR interfaces to copy
the image to BIOS reserved memory and validate the SHA256
checksums.

Cloud Service Providers that operate fleets of servers have reported
[1] occasions where they can detect that a CPU has gone bad due to
effects like electromigration, or isolated manufacturing defects.
However, that detection method is A/B testing seemingly random
application failures looking for a pattern. In-Field Scan (IFS) is
a driver for a platform capability to load a crafted 'scan image'
to run targeted low level diagnostics outside of the CPU's architectural
error detection capabilities.
Stub version of driver just does initial part of check for the IFS
feature. MSR_IA32_CORE_CAPS must enumerate the presence of the

IFS is a CPU feature that allows a binary blob, similar to microcode,
to be loaded and consumed to perform low level validation of CPU
circuitry. In fact, it carries the same Processor Signature
(family/model/stepping) details that are contained in Intel microcode
blobs.
In support of an IFS driver to trigger loading, validation, and running
of these tests blobs, make the functionality of cpu_signatures_match()
and collect_cpu_info_early() available outside of the microcode driver.
Add an "intel_" prefix and drop the "_early" suffix from
collect_cpu_info_early() and EXPORT_SYMBOL_GPL() it. Add
declaration to x86 <asm/cpu.h>
Make cpu_signatures_match() an inline function in x86 <asm/cpu.h>,
and also give it an "intel_" prefix.
No functional change intended.

The debugfs code is lazy, and since it only keeps the bottom byte of
each connect_info register to save space, it also treats the whole thing
as the device_type since the other bits were reserved anyway. Upon
closer inspection, though, this is no longer true on newer IP versions,
so let's be good and decode the exact field properly. This should help
it not get confused when a Component Aggregation Layer is present (which
is already implied if Node IDs are found for both device addresses
represented by the next two lines of the table).

IPv6 addresses which are used for tunnels are stored in a hash table
with reference counting. When a new GRE tunnel is configured, the driver
is notified and configures it in hardware.
Currently, any change in the tunnel is not applied in the driver. It
means that if the remote address is changed, the driver is not aware of
this change and the first address will be used.
This behavior results in a warning [1] in scenarios such as the
following:
# ip link add name gre1 type ip6gre local 2000::3 remote 2000::fffe tos inherit ttl inherit
# ip link set name gre1 type ip6gre local 2000::3 remote 2000::ffff ttl inherit
# ip link delete gre1
The change of the address is not applied in the driver. Currently, the
driver uses the remote address which is stored in the 'parms' of the
overlay device. When the tunnel is removed, the new IPv6 address is
used, the driver tries to release it, but as it is not aware of the
change, this address is not configured and it warns about releasing non
existing IPv6 address.
Fix it by using the IPv6 address which is cached in the IPIP entry, this
address is the last one that the driver used, so even in cases such the
above, the first address will be released, without any warning.

*nfp: VF rate limit support
this short series adds VF rate limiting to the NFP driver.
The first patch, as suggested by Jakub Kicinski, adds a helper
to check that ndo_set_vf_rate() rate parameters are sane.
It also provides a place for further parameter checking to live,
if needed in future.
The second patch adds VF rate limit support to the NFP driver.
It addresses several comments made on v1, including removing
the parameter check that is now provided by the helper added
in the first patch.

Add VF rate limit feature
This patch enhances the NFP driver to supports assignment of
both max_tx_rate and min_tx_rate to VFs
The template of configurations below is all supported.
e.g.
# ip link set $DEV vf $VF_NUM max_tx_rate $RATE_VALUE
# ip link set $DEV vf $VF_NUM min_tx_rate $RATE_VALUE
# ip link set $DEV vf $VF_NUM max_tx_rate $RATE_VALUE \
min_tx_rate $RATE_VALUE
# ip link set $DEV vf $VF_NUM min_tx_rate $RATE_VALUE \
max_tx_rate $RATE_VALUE
The max RATE_VALUE is limited to 0xFFFF which is about
63Gbps (using 1024 for 1G)

When calling ndo_set_vf_rate() the max_tx_rate parameter may be zero,
in which case the setting is cleared, or it must be greater or equal to
min_tx_rate.
Enforce this requirement on all calls to ndo_set_vf_rate via a wrapper
which also only calls ndo_set_vf_rate() if defined by the driver.

The ID register table should have one entry per ID register but
currently has two entries for ID_AA64ISAR2_EL1. Only one entry has an
override, and get_arm64_ftr_reg() can end up choosing the other, causing
the override to be ignored. Fix this by removing the duplicate entry.
While here, also make the check in sort_ftr_regs() more strict so that
duplicate entries can't be added in the future.
