The writeback enable logic was incorrectly implemented (due to
misunderstanding what the side effects of the implementation would be
during polling).
Fix this logic issue, while implementing a new feature allowing the user
to control the writeback frequency using the knobs for controlling
interrupt throttling that we already have. Basically if you leave
adaptive interrupts enabled, the writeback frequency will be varied even
if busy_polling or if napi-poll is in use. If the interrupt rates are
set to a fixed value by ethtool -C and adaptive is off, the driver will
allow the user-set interrupt rate to guide how frequently the hardware
will complete descriptors to the driver.
Effectively the user will get a control over the hardware efficiency,
allowing the choice between immediate interrupts or delayed up to a
maximum of the interrupt rate, even when interrupts are disabled
during polling.

The core clock frequency is currently hardcoded at 446 MHz for the RL

There is an issue with some NVMs where an already existent LLDP
filter is blocking the creation of a filter to allow LLDP packets

LLDP agent is disabled (e.g. software based DCBx).
Implement the new AQ command to allow adding VSI destinations to

The function br_mrp_port_switchdev_set_state was called both with MRP
port state and STP port state, which is an issue because they don't
match exactly.
Therefore, update the function to be used only with STP port state and
use the id SWITCHDEV_ATTR_ID_PORT_STP_STATE.
The choice of using STP over MRP is that the drivers already implement
SWITCHDEV_ATTR_ID_PORT_STP_STATE and already in SW we update the port
STP state.

uplink representor. Remove implicit and explicit assumptions of tunnel always

HW offloads model
For hardware offload the goal is to mach packet on both rules without exposing
it to software on tunnel endpoint VF. In order to achieve this for tx, TC
implementation marks encap rules with tunnel endpoint on mlx5 VF of same eswitch
with MLX5_ESW_DEST_CHAIN_WITH_SRC_PORT_CHANGE flag and adds header modification
rule to overwrite packet source port to the value of tunnel VF. Eswitch code is
modified to recirculate such packets after source port value is changed, which
allows second tx rules to match.
For rx path indirect table infrastructure is used to allow fully processing VF
tunnel traffic in hardware. To implement such pipeline driver needs to program
the hardware after matching on UL rule to overwrite source vport from UL to
tunnel VF and recirculate the packet to the root table to allow matching on the
rule installed on tunnel VF. For this, indirect table matches all encapsulated
traffic by tunnel parameters and all other IP traffic is sent to tunnel VF by
the miss rule. Such configuration will cause packet to appear on VF representor
instead of VF itself if packet has been matches by indirect table rule based on
tunnel parameters but missed on second rule (after recirculation). Handle such
case by marking packets processed by indirect table with special 0xFFF value in
reg_c1 and extending slow table with additional flow group that matches on
reg_c0 (source port value set by indirect tables) and reg_c1 (special 0xFFF
mark). When creating offloads fdb tables, install one rule per VF vport to match
on recirculated miss packets and redirect them to appropriate VF vport.
Routing events
In order to support routing changes and migration of tunnel device between
different endpoint VFs, implement routing infrastructure and update it with FIB
events. Routing entry table is introduced to mlx5 TC. Every rx and tx VF tunnel
rule is attached to a routing entry, which is shared for rules of same tunnel.
On FIB event the work is scheduled to delete/recreate all rules of affected
tunnel.
Note: only vxlan tunnel type is supported by this series.

The set of required attributes for a given SRv6 behavior is identified
using a bitmap stored in an unsigned long, since the initial design of SRv6
networking in Linux. Recently the same approach has been used for
identifying the optional attributes.
However, the number of attributes supported by SRv6 behaviors depends on
the size of the unsigned long type which changes with the architecture.
Indeed, on a 64-bit architecture, an SRv6 behavior can support up to 64
attributes while on a 32-bit architecture it can support at most 32
attributes.
To fool-proof the processing of SRv6 behaviors we verify, at compile time,
that the set of all supported SRv6 attributes can be encoded into a bitmap
stored in an unsigned long. Otherwise, kernel build fails forcing
developers to reconsider adding a new attribute or extend the total
number of supported attributes by the SRv6 behaviors.
Moreover, we replace all patterns (1 << i) with the macro SEG6_F_ATTR(i) in
order to address potential overflow issues caused by 32-bit signed
arithmetic.
Thanks to Colin Ian King for catching the overflow problem, providing a
solution and inspiring this patch.
Thanks to Jakub Kicinski for his useful suggestions during the design of
this patch.
v2:
- remove the SEG6_LOCAL_MAX_SUPP which is not strictly needed: it can
be derived from the unsigned long type. Thanks to David Ahern for
pointing it out.

When writing a tool for enabling events in the tracing system,
an anomaly was discovered. The top level event "enable" file would
never show "1" when all events were enabled. The system and event
"enable" files worked as expected. The reason was because the top
level event "enable" file included the "ftrace" tracer events,
which are not controlled by the "enable" file and would cause the
output to be wrong. This appears to have been a bug since it was created.

The sctp transport seq_file iterators take a reference to the transport
in the ->start and ->next functions and releases the reference in the
->show function. The preferred handling for such resources is to
release them in the subsequent ->next or ->stop function call.
Since Commit 1f4aace60b ("fs/seq_file.c: simplify seq_file iteration
code and interface") there is no guarantee that ->show will be called
after ->next, so this function can now leak references.
So move the sctp_transport_put() call to ->next and ->stop.

This issue starts from linux-5.10-rc1, I reproduced this issue on my
Dell Inspiron 7447 with BT adapter 0cf3:e005, the kernel will print
out: "Bluetooth: hci0: don't support firmware rome 0x31010000", and
someone else also reported the similar issue to bugzilla #211571.
I found this is a regression introduced by 'commit b40f58b973
("Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support"), the
patch assumed that if high ROM version is not zero, it is an adapter
on WCN6855, but many old adapters don't need to load rampatch or nvm,
and they have non-zero high ROM version.
To fix it, let the driver match the rom_version in the
qca_devices_table first, if there is no entry matched, check the
high ROM version, if it is not zero, we assume this adapter is ready
to work and no need to load rampatch and nvm like previously.

If the maximum performance level taken for computing the
arch_max_freq_ratio value used in the x86 scale-invariance code is
higher than the one corresponding to the cpuinfo.max_freq value
coming from the acpi_cpufreq driver, the scale-invariant utilization
falls below 100% even if the CPU runs at cpuinfo.max_freq or slightly
faster, which causes the schedutil governor to select a frequency
below cpuinfo.max_freq. That frequency corresponds to a frequency
table entry below the maximum performance level necessary to get to
the "boost" range of CPU frequencies which prevents "boost"
frequencies from being used in some workloads.
While this issue is related to scale-invariance, it may be amplified
by commit db865272d9 ("cpufreq: Avoid configuring old governors as
default with intel_pstate") from the 5.10 development cycle which
made it extremely easy to default to schedutil even if the preferred
driver is acpi_cpufreq as long as intel_pstate is built too, because
the mere presence of the latter effectively removes the ondemand
governor from the defaults. Distro kernels are likely to include
both intel_pstate and acpi_cpufreq on x86, so their users who cannot
use intel_pstate or choose to use acpi_cpufreq may easily be
affectecd by this issue.
If CPPC is available, it can be used to address this issue by
extending the frequency tables created by acpi_cpufreq to cover the
entire available frequency range (including "boost" frequencies) for
each CPU, but if CPPC is not there, acpi_cpufreq has no idea what
the maximum "boost" frequency is and the frequency tables created by
it cannot be extended in a meaningful way, so in that case make it
ask the arch scale-invariance code to to use the "nominal" performance
level for CPU utilization scaling in order to avoid the issue at hand.

A severe performance regression on AMD EPYC processors when using
the schedutil scaling governor was discovered by Phoronix.com and
attributed to the following commits:
41ea667227 ("x86, sched: Calculate frequency invariance for AMD
systems")
976df7e573 ("x86, sched: Use midpoint of max_boost and max_P for
frequency invariance on AMD EPYC")
The source of the problem is that the maximum performance level taken
for computing the arch_max_freq_ratio value used in the x86 scale-
invariance code is higher than the one corresponding to the
cpuinfo.max_freq value coming from the acpi_cpufreq driver.
This effectively causes the scale-invariant utilization to fall below
100% even if the CPU runs at cpuinfo.max_freq or slightly faster, so
the schedutil governor selects a frequency below cpuinfo.max_freq
then. That frequency corresponds to a frequency table entry below
the maximum performance level necessary to get to the "boost" range
of CPU frequencies.
However, if the cpuinfo.max_freq value coming from acpi_cpufreq was
higher, the schedutil governor would select higher frequencies which
in turn would allow acpi_cpufreq to set more adequate performance
levels and to get to the "boost" range of CPU frequencies more often.
This issue affects any systems where acpi_cpufreq is used and the
"boost" (or "turbo") frequencies are enabled, not just AMD EPYC.
Moreover, commit db865272d9 ("cpufreq: Avoid configuring old
governors as default with intel_pstate") from the 5.10 development
cycle made it extremely easy to default to schedutil even if the
preferred driver is acpi_cpufreq as long as intel_pstate is built
too, because the mere presence of the latter effectively removes the
ondemand governor from the defaults. Distro kernels are likely to
include both intel_pstate and acpi_cpufreq on x86, so their users
who cannot use intel_pstate or choose to use acpi_cpufreq may
easily be affectecd by this issue.
To address this issue, extend the frequency table constructed by
acpi_cpufreq for each CPU to cover the entire range of available
frequencies (including the "boost" ones) if CPPC is available and
indicates that "boost" (or "turbo") frequencies are enabled. That
causes cpuinfo.max_freq to become the maximum "boost" frequency of
the given CPU (instead of the maximum frequency returned by the ACPI
_PSS object that corresponds to the "nominal" performance level).

This reverts commit 842067940a.
For some solutions e.g. sound/soc/intel/catpt, DW DMA is part of a
compound device (in that very example, domains: ADSP, SSP0, SSP1, DMA0
and DMA1 are part of a single entity) rather than being a standalone
one. Driver for said device may enlist DMA to transfer data during
suspend or resume sequences.
Manipulating RPM explicitly in dw's DMA request and release channel
functions causes suspend() to also invoke resume() for the exact same
device. Similar situation occurs for resume() sequence. Effectively
renders device dysfunctional after first suspend() attempt. Revert the
change to address the problem.

100GbE Intel Wired LAN Driver Updates 2021-02-05
This series contains updates to ice driver only.
Jake adds adds reporting of timeout length during devlink flash and
implements support to report devlink info regarding the version of
firmware that is stored (downloaded) to the device, but is not yet active.
ice_devlink_info_get will report "stored" versions when there is no
pending flash update. Version info includes the UNDI Option ROM, the
Netlist module, and the fw.bundle_id.
Gustavo A. R. Silva replaces a one-element array to flexible-array
member.
Bruce utilizes flex_array_size() helper and removes dead code on a check
for a condition that can't occur.
v2:
* removed security revision implementation, and re-ordered patches to
account for this removal
* squashed patches implementing ice_read_flash_module to avoid patches
refactoring the implementation of a previous patch in the series
* modify ice_devlink_info_get to always report "stored" versions instead
of only reporting them when a pending flash update is ready.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
ice: remove dead code
ice: use flex_array_size where possible
ice: Replace one-element array with flexible-array member
ice: display stored UNDI firmware version via devlink info
ice: display stored netlist versions via devlink info
ice: display some stored NVM versions via devlink info
ice: introduce function for reading from flash modules
ice: cache NVM module bank information
ice: introduce context struct for info report
ice: create flash_info structure and separate NVM version
ice: report timeout length for erasing during devlink flash

* Two fixes related to STRICT_KERNEL_RWX: one that fixes some

* A fix to disallow the selection of MAXPHYSMEM_2GB on RV32, which isn't

there will likely be something coming next week.
