Which ones?  Does anything need to be done to add new tests to the list?

Note that even if "all" tests are being run (via
CONFIG_KUNIT_ALL_TESTS=y), that includes only the tests whose
dependencies are met.  There can be additional kconfig dependencies.

The kernel has optimized crypto and/or CRC code for the following
architectures: arm, arm64, mips, powerpc, riscv, s390, sparc, x86.  In
many cases there's also a finer division based on CPU features.

So I'm looking for testing on as many platforms as possible.  But some
x86_64 platform is a good start, certainly better than nothing.
