let's also convert the qemu test to use nft at the same time.

For some modules, modalias is generated using the modpost utility and
the section is added to the module file.
When a module is added inside vmlinux, modpost does not generate
modalias for such modules and the information is lost.
As a result kmod (which uses modules.builtin.modinfo in userspace)
In order to avoid symbol conflicts if they appear in the same binary, a
more unique alias identifier can be generated.

This commit adds a new kernel selftest to verify RTNLGRP_IPV4_MCADDR
and RTNLGRP_IPV6_MCADDR notifications. The test works by adding and
removing a dummy interface and then confirming that the system
correctly receives join and removal notifications for the 224.0.0.1
and ff02::1 multicast addresses

The __MODULE_INFO macros always use __MODULE_INFO_PREFIX. The only way
to use a different prefix is to override __MODULE_INFO_PREFIX, which is
not very useful.
The new macro will be used in file2alias.c to generate modalias for
builtin modules.

Hello,
this is the v2 of the many args series for arm64, being itself a revival
of Xu Kuhoai's work to enable larger arguments count for BPF programs on
ARM64 ([1]).
The discussions in v1 shed some light on some issues around specific
cases, for example with functions passing struct on stack with
From: Xu Kuohai
Currently ARM64 bpf trampoline supports up to 8 function arguments.
According to the statistics from commit
473e3150e30a ("bpf, x86: allow function arguments up to 12 for TRACING"),
there are about 200 functions accept 9 to 12 arguments, so adding support
for up to 12 function arg
Now that support for up to 12 args is enabled for tracing programs on
ARM64, enable the existing tests for this feature on this architecture.

glibc does not define SYS_futex for 32-bit architectures using 64-bit
time_t e.g. riscv32, therefore this test fails to compile since it does not
find SYS_futex in C library headers. Define SYS_futex as SYS_futex_time64
in this situation to ensure successful compilation and compatibility.

The blogic_pci_tbl structure is used by the MODULE_DEVICE_TABLE macro.
There is no longer a need to protect it with the MODULE condition, since
this no longer causes the compiler to warn about an unused variable.

arch_timer_edge_cases tries to migrate itself across host cpus. Before
the first test it migrates to cpu 0 by setting up an affinity mask with
only bit 0 set. After that it looks for the next possible cpu in the
current affinity mask which still has only bit 0 set. So there is no
migration at all.

This patch implements in order support for both split virtqueue and
packed virtqueue.
Benchmark with KVM guest + testpmd on the host shows:
For split virtqueue: no obvious differences were noticed
For packed virtqueue:
1) RX gets 3.1% PPS improvements from 6.3 Mpps to 6.5 Mpps
2) TX gets 4.6% P
This patch factors out the split core detaching logic that could be
reused by in order feature into a dedicated function.

This commit introduces a new vmtest.sh runner for vsock.
It uses virtme-ng/qemu to run tests in a VM. The tests validate G2H,
H2G, and loopback. The testing tools from tools/testing/vsock/ are
reused. Currently, only vsock_test is used.
VMCI and hyperv support is included in the config file to be

Use TH_LOG to report failure when reading /proc//stat in
get_proc_stat(), following kernel test framework conventions.
Previously, printf() was used which is discouraged.

Corrected several typos in virtio_ring.c for improved clarity and
consistency. Fixes include:
- "dind't" -> "didn't"
- "use" -> "uses" in DMA mapping context
- "can been used" -> "can be used"
- "buf size for sync" -> "buffer size to synchronize"
No functional changes.

Corrected several spelling mistakes in code comments, including:
- "bock" -> "block"
- "valued" -> "value"
- "actipn" -> "action"
- "accidentially" -> "accidentally"
- Improved grammar in a few places for clarity.
These changes are purely cosmetic and do not affect functionality.

Since MODULE_DEVICE_TABLE no longer depends on whether the module is
built separately or compiled into the kernel, it now makes sense to
always define DEVICE_TABLE. In this case, even if the module is in the
kernel, correct module.builtin.modaliases will be generated.

Yes, it looks like the same issue.
arch_timer_edge_cases uses ~0 as the maximum counter value, however there's
no architectural guarantee that this is valid.
Figure out the effective counter width based on the effective frequency
like it's done by the kernel.
Note that the following subtest only worked since the counter initialize
