Add tests for memblock_alloc_exact_nid_raw() that are very similar to
the range tests for memblock_alloc_try_nid_raw().

memblock_alloc_exact_nid_raw(NUMA_NO_NODE) behaves exactly the way
memblock_alloc_try_nid_raw(NUMA_NO_NODE) behaves -- which is essentially
memblock_alloc_raw().
So do we really need a separate set of tests for these?
Instead of a separate set of tests, I could add a flag for
memblock_alloc_exact_nid_raw() to test_flags so that the range tests in
alloc_nid_api.c could be run with that flag. Do you think I should do
that, or omit tests for memblock_alloc_exact_nid_raw(NUMA_NO_NODE)
altogether?
Good question. From an API point of view, it makes sense to test that
API somehow. With implementation in mind, it doesn't make too much sense
to test it twice.
Whatever you prefer :) Just wanted to point out that separate tests
don't make sense -- using a flag would be cleaner.
