Thanks. Will update document in next version.

I think you mean to have exclusive lists for fast-tests and nohuge-tests.
Overlapped cases will run twice if both test suites are opted in.
But the two runs are not the same, one runs with hugepage and 
the other runs in no-huge mode.

If fast-tests list is splited,  we will need to always run multiple suites
to cover all fast tests.
We can keep x86 to run only fast-tests suite to avoid extra test runs if
they are not necessary. Thoughts?
