Since gcc supports flag out operands for inline assemblies there is always
the question when this feature should be used and if it is worth all the
ifdefs that come with that.
In order to avoid that provide similar macros like x86 which can be used
for all inline assemblies which extract the condition code. Depending on
compiler features the generated code will either always contain an ipm+srl
instruction pair, which extracts the condition code, or alternatively let
the compiler handle this completely.

The current "measurement_chars" CHPID sysfs attribute exposes only a
limited, validity-filtered portion of data from the associated Channel-
Measurements Characteristics Block (CMCB). New machine models add data
that is relevant for userspace tooling to the "header"-portion of the
CMCB. This data that is not currently accessible to userspace.
To prevent having to add new sysfs attributes whenever a new bit of data
is added to the CMCB "header", add a new sysfs attribute named
"measurement_chars_full" that exposes the full, unfiltered CMCB.

OEMs can use the spk-id-gpios ACPI property to indicate the type of
speakers fitted to a device.
Attempt to read a spk-id value using the GPIO method when a usable
spk-id value is not obtained from the 01fa-spk-id-val ACPI property.
Obtaining the spk-id value has been moved earlier in the function to the
other sidecar block, so that an -EPROBE_DEFER from a GPIO driver is
handled more efficiently.

The kdump kernel is broken on SME systems with CONFIG_IMA_KEXEC=y enabled.
Debugging traced the issue back to
b69a2afd5afc ("x86/kexec: Carry forward IMA measurement log on kexec").
Testing was previously not conducted on SME systems with CONFIG_IMA_KEXEC
enabled, which led to the oversight, with the following incarnation:
...

Three types of setup_data info
— SETUP_EFI,
- SETUP_IMA, and
- SETUP_RNG_SEED
are passed to the kexec/kdump kernel. Only the ima_kexec buffer
experienced incorrect decryption. Debugging identified a bug in
early_memremap_is_setup_data(), where an incorrect range calculation
occurred due to the len variable in struct setup_data ended up only
representing the length of the data field, excluding the struct's size,
and thus leading to miscalculation.
Address a similar issue in memremap_is_setup_data() while at it.

of_find_compatible_node() increments the node's refcount, and it must be
decremented again with a call to of_node_put() when the pointer is no
longer required to avoid leaking the resource.
Instead of adding the missing calls to of_node_put() in all execution
paths, use the cleanup attribute for 'arm_timer' by means of the
__free() macro, which automatically calls of_node_put() when the
variable goes out of scope.

In a multi-cluster MIPS system, there are multiple GICs - one in each
cluster - each of which has its independent counter. The counters in
each GIC are not synchronized in any way, so they can drift relative
to one another through the lifetime of the system. This is problematic
for a clock source which ought to be global.
Avoid problems by always accessing cluster 0's counter, using
cross-cluster register access. This adds overhead so it is applied only
on multi-cluster systems.

The sp804 is currently only user selectable if COMPILE_TEST, this was
done by commit dfc82faad725 ("clocksource/drivers/sp804: Add
COMPILE_TEST to CONFIG_ARM_TIMER_SP804") in order to avoid it being
spuriously offered on platforms that won't have the hardware since it's
generally only seen on Arm based platforms. This config is overly
restrictive, while platforms that rely on the SP804 do select it in
their Kconfig there are others such as the Arm fast models which have a
SP804 available but currently unused by Linux. Relax the dependency to
allow it to be user selectable on arm and arm64 to avoid surprises and
in case someone comes up with a use for extra timer hardware.

Introduce RVU representors
This series adds representor support for each rvu devices.
When switchdev mode is enabled, representor netdev is registered
for each rvu device. In implementation of representor model,
one NIX HW LF with multiple SQ and RQ is reserved, where each
RQ and SQ of the LF are mapped to a representor. A loopback channel
is reserved to support packet path between representors and VFs.
CN10K silicon supports 2 types of MACs, RPM and SDP. This
patch set adds representor support for both RPM and SDP MAC
interfaces.
- Patch 1: Implements basic representor driver.
- Patch 2: Add devlink support to create representor netdevs that
can be used to manage VFs.
- Patch 3: Implements basec netdev_ndo_ops.
- Patch 4: Installs tcam rules to route packets between representor and
VFs.
- Patch 5: Enables fetching VF stats via representor interface
- Patch 6: Adds support to sync link state between representors and VFs .
- Patch 7: Enables configuring VF MTU via representor netdevs.
- Patch 8: Adds representors for sdp MAC.
- Patch 9: Adds devlink port support.
- Patch 10: Implements offload stats.
- Patch 11: Implements tc offload support.
- patch 12: Adds documentation for rvu port representor.

Implements tc offload support for rvu representors.
Usage example:
- Add tc rule to drop packets with vlan id 3 using port
representor(Rpf1vf0).
# tc filter add dev Rpf1vf0 protocol 802.1Q parent ffff: flower
vlan_id 3 vlan_ethtype ipv4 skip_sw action drop
- Redirect packets with vlan id 5 and IPv4 packets to eth1,
after stripping vlan header.
# tc filter add dev Rpf1vf0 ingress protocol 802.1Q flower vlan_id 5
vlan_ethtype ipv4 skip_sw action vlan pop action mirred ingress
redirect dev eth1

Hardware supports different types of MACs eg RPM, SDP, LBK.
LBK is for internal Tx->Rx HW loopback path. RPM and SDP MACs support
ingress/egress pkt IO on interfaces with different set of capabilities
like interface modes. At the time of netdev driver registration PF will
seek MAC related information from Admin function driver
'drivers/net/ethernet/marvell/octeontx2/af' and sets up ingress/egress
queues etc such that pkt IO on the channels of these different MACs is
possible. This patch add representors for SDP MAC.

Adds support to manage the mtu configuration for VF through representor.
On update of representor mtu a mbox notification is send
to VF to update its mtu.
This feature is implemented based on the "Network Function Representors"
kernel documentation.
"
Setting an MTU on the representor should cause that same MTU
to be reported to the representee.

Implements the below requirement mentioned
in the representors documentation.
"
The representee's link state is controlled through the
representor. Setting the representor administratively UP
or DOWN should cause carrier ON or OFF at the representee.
"
This patch enables
- Reflecting the link state of representor based on the VF state and
link state of VF based on representor.
- On VF interface up/down a notification is sent via mbox to representor
to update the link state.
eg: ip link set eth0 up/down will disable carrier on/off
of the corresponding representor(r0p1) interface.
- On representor interface up/down will cause the link state update of VF.
eg: ip link set r0p1 up/down will disable carrier on/off
of the corresponding representee(eth0) interface.
