The thuge-gen test_mmap() and test_shmget() tests are repeatedly run for a
variety of sizes but always report the result of their test with the same
name, meaning that automated sysetms running the tests are unable to
distinguish between the various tests. Add the supplied sizes to the logged
test names to distinguish between runs.

Support for 32-bit s390 is very easy to implement and useful for
testing. For example I used to test some generic compat_ptr() logic,
which is only testable on 32-bit s390.
The series depends on my other series
"selftests/nolibc: test kernel configuration cleanups".
(It's not a hard dependency, only a minor diff conflict)

Add a new selftest to verify netconsole's handling of messages that
exceed the packet size limit and require fragmentation. The test sends
messages with varying sizes and userdata, validating that:
1. Large messages are correctly fragmented and reassembled
2. Userdata fields are properly preserved across fragments
3. Messages work correctly with and without kernel release version
appending
The test creates a networking environment using netdevsim, sends
messages through /dev/kmsg, and verifies the received fragments maintain
message integrity.

The script uses non-POSIX features like `[[` for conditionals and hence
does not work when run with a POSIX /bin/sh.
Change the shebang to /bin/bash instead, like the other tests in cgroup.

Greetings:
Welcome to v3. No functional changes, see changelog below.
This is an attempt to followup on something Jakub asked me about [1],
adding an xsk attribute to queues and more clearly documenting which
queues are linked to NAPIs...
After the RFC [2], Jakub suggested creating an empty nest for queues
which have a pool, so I've adjusted this version to work that way.
The nest can be extended in the future to express attributes about XSK
as needed. Queues which are not used for AF_XDP do not have the xsk
attribute present.
I've run the included test on:
- my mlx5 machine (via NETIF=)
- without setting NETIF
And the test seems to pass in both cases.
Thanks,
Joe

v3:
- Change comment format in patch 2 to avoid kdoc warnings. No other
changes.
v2: https://lore.kernel.org/all/20250203185828.19334-1-jdamato@fastly.com/
- Switched from RFC to actual submission now that net-next is open
- Adjusted patch 1 to include an empty nest as suggested by Jakub
- Adjusted patch 2 to update the test based on changes to patch 1, and
to incorporate some Python feedback from Jakub :)
