On big-endian systems the 32-bit low and high halves need to be swapped,

Found by the string_test_memset64 KUnit test.

Good catch! I guess that likely means you are the first one to
run kunit test on armbe since the tests got added. Did you find
any other differences between BE and LE kernels running kunit?

No other differences with the default set of tests.
There was a failure for both in test_polyval_preparekey_in_irqs, see [0].
To get some more exposure I propose a new kunit QEMU configuration in [1].
