Heh, tests. We have tests to keep fixing them. :)
Marc, can you add a hunk to patch "Implement fw_cfg DMA interface" that
changes the above test to mask out everything but bit 0? I don't think
we need to test DMA in the test suite right now (can be done in another
series I guess), but DMA's presence shouldn't break the current test. I
guess something like this would suffice:
diff --git a/tests/fw_cfg-test.c b/tests/fw_cfg-test.c
index 9be78e9..27f115d 100644
