For ia64, I was most concerned about alignment issues. So anything (UP
or SMP) that exercises code paths is helpful. The only SMP-specific
things to test are power-off on shutdown. Run it a bunch of times to be
sure that it continues to work. Note this isn't in the acpi locking
path but ACPI-CA has its own locks which are now not redundantly covered
by Giant. It has been running this way in Linux for a year or so.
Still, it's good to have that test coverage too.
