It's certainly possible, but the code is verbose and ugly (IMO), which
means it will be harder for other to review.

Understood, but IMO this particular change is safe-ish:

  - We're already intersecting with selftests
  - The odds of a conflict are very low
  - Andy is already involved in SGX


There are also other options:

  1. Use kselftest_harness.h as-is via #undef __EXPECT.  I actually would
     have gone with this option except the header also defines a function
     and we end up with a compiler error due to an unused function :-(

  2. Upstream the change separately from SGX, similar to the
     FEATURE_CONTROL handling.  E.g. I think the KVM selftests could
     use the operators, so there would even be concrete usage.
