With the current approach we have an extra check in the
cppc_cpufreq_get_rate() callback, which checks if hisilicon's get rate
implementation should be used instead. While it works fine, the approach
isn't very straight forward, over that we have an extra check in the
routine.
Rearrange code and update the cpufreq driver's get() callback pointer
directly for the hisilicon case. This gets the extra variable is removed
and the extra check isn't required anymore as well.

Commit 0c868627e6 (cpufreq: dt: Allow platform specific
intermediate callbacks) added two function pointers to the
struct cpufreq_dt_platform_data. However, armada37xx_cpufreq_driver_init()
has this struct (pdata) located on the stack and uses only "suspend"
and "resume" fields. So these newly added "get_intermediate" and
"target_intermediate" pointers are uninitialized and contain arbitrary
non-null values, causing all kinds of trouble.
For instance, here is an oops on espressobin after an attempt to change
the cpefreq governor:

Currently, short messages (less than 4 bytes after the length header)
will break the stream of messages. This is unnecessary, since we can
still parse messages even if they're too short to contain any usable
data. This is also bogus, as keepalive messages (a single 0xff byte),
though not needed with TCP encapsulation, should be allowed.
This patch changes the stream parser so that short messages are
accepted and dropped in the kernel. Messages that contain a valid SPI
or non-ESP header are processed as before.

Recently ASPM handling was changed to allow ASPM on PCIe-to-PCI/PCI-X
bridges. Unfortunately the ASMedia ASM1083/1085 PCIe to PCI bridge device
doesn't seem to function properly with ASPM enabled. On an Asus PRIME
H270-PRO motherboard, it causes errors like these:
pcieport 0000:00:1c.0: AER: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Transmitter ID)
pcieport 0000:00:1c.0: AER: device [8086:a292] error status/mask=00003000/00002000
pcieport 0000:00:1c.0: AER: [12] Timeout
pcieport 0000:00:1c.0: AER: Corrected error received: 0000:00:1c.0
pcieport 0000:00:1c.0: AER: can't find device of ID00e0
In addition to flooding the kernel log, this also causes the machine to
wake up immediately after suspend is initiated.
The device advertises ASPM L0s and L1 support in the Link Capabilities
register, but the ASMedia web page for ASM1083 [1] claims "No PCIe ASPM
support".
Windows 10 (build 2004) enables L0s, but it also logs correctable PCIe
errors.
Add a quirk to disable ASPM for this device.

- auxtrace_record__init() is called only once, so there is no point in
using a static variable to cache the results of
find_all_arm_spe_pmus(), make it local and free the results after use.
- Another reason is, even though SPE is micro-architecture dependent,
but so far it only supports "statistical-profiling-extension-v1" and
we have no chance to use multiple SPE's PMU events in Perf command.
So remove the useless check code to make it clear.

-e cache-misses sleep 1
[root@localhost 0620]#
The current code can only work if the only event to be traced is an
'arm_spe_x', or if it is the last event to be specified. Otherwise the
last event type will be checked against all the arm_spe_pmus[i]->types,
none will match and an out of bound 'i' index will be used in
arm_spe_recording_init().
We don't support concurrent multiple arm_spe_x events currently, that
is checked in arm_spe_recording_options(), and it will show the relevant
info. So add the check and record of the first found 'arm_spe_pmu' to
fix this issue here.

Pull 9p fixes from Dominique Martinet:
"A couple of syzcaller fixes for 5.8
The first one in particular has been quite noisy ("broke" in -rc5) so
this would be worth landing even this late even if users likely won't
see a difference"

388c8c16ab ("PCI: add routines for debugging and handling lost

====================
mlxsw fixes
This patch set contains various fixes for mlxsw.
Patches #1-#2 fix two trap related issues introduced in previous cycle.
Patches #3-#5 fix rare use-after-frees discovered by syzkaller. After
over a week of fuzzing with the fixes, the bugs did not reproduce.
Patch #6 from Amit fixes an issue in the ethtool selftest that was
recently discovered after running the test on a new platform that
supports only 1Gbps and 10Gbps speeds.

The test case check_highest_speed_is_chosen() configures $h1 to
advertise a subset of its supported speeds and checks that $h2 chooses
the highest speed from the subset.
To find the common advertised speeds between $h1 and $h2,
common_speeds_get() is called.
Currently, the first speed returned from common_speeds_get() is removed
claiming "h1 does not advertise this speed". The claim is wrong because
the function is called after $h1 already advertised a subset of speeds.
In case $h1 supports only two speeds, it will advertise a single speed
which will be later removed because of previously mentioned bug. This
results in the test needlessly failing. When more than two speeds are
supported this is not an issue because the first advertised speed
is the lowest one.
Fix this by not removing any speed from the list of commonly advertised
speeds.

The lifetime of the Rx listener item ('rxl_item') is managed using RCU,
but is dereferenced outside of RCU read-side critical section, which can
lead to a use-after-free.
Fix this by increasing the scope of the RCU read-side critical section.

Cited commit mistakenly removed the trap group for externally routed
packets (e.g., via the management interface) and grouped locally routed
and externally routed packet traps under the same group, thereby
subjecting them to the same policer.
This can result in problems, for example, when FRR is restarted and
suddenly all transient traffic is trapped to the CPU because of a
default route through the management interface. Locally routed packets
required to re-establish a BGP connection will never reach the CPU and
the routing tables will not be re-populated.
Fix this by using a different trap group for externally routed packets.
