The function get_l3_stats() from the test hw_stats_l3.sh will be useful for
any test that wishes to work with L3 stats. Furthermore, it is easy to
generalize to other HW stats suites (for when such are added). Therefore,
move the code to lib.sh, rewrite it to have the same interface as the other
stats-collecting functions, and generalize to take the name of the HW stats
suite to collect as an argument.

The 'ping' utility is able to manage two kind of sockets (raw or icmp),
depending on the sysctl ping_group_range. By default, ping_group_range is
set to '1 0', which forces ping to use an ip raw socket.
Let's replay the ping tests by allowing 'ping' to use the ip icmp socket.
After the previous patch, ipv4 tests results are the same with both kinds
of socket. For ipv6, there are a lot a new failures (the previous patch
fixes only two cases).

all_cpus is merged into during propagation. Initially all_cpus is set
from PMU sysfs. perf_evlist__set_maps() will recompute it and change
evsel->cpus to user_requested_cpus if they are given.
If all_cpus isn't cleared then the union of the user_requested_cpus and
PMU sysfs values is set to all_cpus, whereas just user_requested_cpus is
necessary.
To avoid this make all_cpus empty prior to propagation.

Merge master into next, to bring in commit 5f24d5a579d1 ("mm, hugetlb:

prerequisite for the series converting powerpc to the generic mmap
logic.

As discussed here with Ido Schimmel:
https://patchwork.kernel.org/project/netdevbpf/patch/[email protected]/
the default conform-exceed action is "reclassify", for a reason we don't
really understand.
The point is that hardware can't offload that police action, so not
specifying "conform-exceed" was always wrong, even though the command
used to work in hardware (but not in software) until the kernel started
adding validation for it.
Fix the command used by the selftest by making the policer drop on
exceed, and pass the packet to the next action (goto) on conform.

Rather than relying on the system to have cross toolchains available,
simply download musl.cc's ones and use that libc.so, and then we use it
to fill in a few missing platforms, such as riscv64, riscv64, powerpc64,
and s390x.
Since riscv doesn't have a second serial port in its device description,
we have to use virtio's vport. This is actually the same situation on
ARM, but we were previously hacking QEMU up to work around this, which
required a custom QEMU. Instead just do the vport trick on ARM too.

The parallel tests were added to catch queueing issues from multiple
cores. But what happens in reality when testing tons of processes is
that these separate threads wind up fighting with the scheduler, and we
wind up with contention in places we don't care about that decrease the
chances of hitting a bug. So just do a test with the number of CPU
cores, rather than trying to scale up arbitrarily.

I hate to do this, but I still do not have a good solution to actually
fix this bug across architectures. So just disable it for now, so that
the CI can still deliver actionable results. This commit adds a large
red warning, so that at least the failure isn't lost forever, and
hopefully this can be revisited down the line.

A number of mlxsw-specific QoS tests use manual QoS DCB management. As
such, they need to make sure lldpad is not running, because it would
override the configuration the test has applied using other tools. To that
end, these selftests invoke the bail_on_lldpad() helper, which terminates
the selftest if th lldpad is running.
Some of these tests however first install the bash exit trap, which invokes
a cleanup() at the test exit. If bail_on_lldpad() has terminated the script
even before the setup part was run, the cleanup part will be very confused.
Therefore make sure bail_on_lldpad() is invoked before the cleanup is
registered.
While there are still edge cases where the user terminates the script
before the setup was fully done, this takes care of a common situation
where the cleanup would be invoked in an inconsistent state.

This verifies that if a filter is set up with the wait killable feature
that it obeys the semantics that non-fatal signals are ignored during
a notification after the notification is received.
Cases tested:
* Non-fatal signal prior to receive
* Non-fatal signal during receive
* Fatal signal after receive
The normal signal handling is tested in user_notification_signal. That
behaviour remains unchanged.
On an unsupported kernel, these tests will immediately bail as it relies

EXPORT_SYMBOL of do_exec() was removed in v5.17. Unfortunately,
kernel modules from klitmus7 7.56 have do_exec() at the end of
each kthread.
herdtools7 7.56.1 has addressed the issue.
Update the compatibility table accordingly.
