Michael,
 could you fix it up on commit?
or we could merge v4
   [PATCH v4 13/15] tests: acpi: add simple arm/virt  testcase
which is the same modulo this blacklisting hunk, if
   [RFC PATCH] cputlb: use uint64_t for interim values  for unaligned load
fix is used as prerequisite.

I'd guess it's topic for a separate discussion (considering bios-tables-test
isn't affected it's probably not upto me to pull this trigger).
