Hi all,

After merging the arm64 tree, today's linux-next (arm64 kunit) failed
like this:

[11:04:45] Configuring KUnit Kernel ...
[11:04:45] Building KUnit Kernel ...
Populating config with:
$ make ARCH=arm64 O=/tmp/next/arm64_kunit olddefconfig CROSS_COMPILE=aarch64-linux-gnu-
Building with:
$ make all compile_commands.json scripts_gdb ARCH=arm64 O=/tmp/next/arm64_kunit --jobs=192 CROSS_COMPILE=aarch64-linux-gnu-
[11:05:11] Starting KUnit Kernel (1/1)...
Running tests with:

[11:10:11] Elapsed time: 325.499s total, 0.002s configuring, 25.490s building, 300.006s running

which is not hugely informative.  Looking at what's new in the arm64
tree from yesterday I'd be astonished if this were anything other than
Ard's linear map series.  

This is running on a Graviton 4 system, the kunit command line is:

./tools/testing/kunit/kunit.py run --failed --alltests --kconfig_add CONFIG_KASAN=y --arch arm64 --cross_compile=aarch64-linux-gnu-

I have used the version from next-20260602 instead.
