I agree that this looks a bit goofy.
Originally, this patch just passed around 'tsk' instead of 'xsave_buf'.
But I realized we could go a step further.
The way it stands, it is bisectable and been built in this configuration
for a month or two. I'd really like to keep it this way if possible,
even though it looks a bit goofy.
