Wouldn't it be better to drop this line?

This function uses #if defined(TCG_TARGET_I386) in other places, so I'd use
parentheses here for consistency.

Same here.

Apart from that, I also need this patch to be able to build qemu on fedora
15 :)

You should also probably split the patch in two parts, as it touch
totally different parts of QEMU, and thus is going to be
reviewed/applied by different person. I am fine with the TCG part after
the comments from Christophe, so I'll apply it as soon as the new
version is out.

Thanks; just got hit by this.

However, there are a couple of whitespace issues:

Both these lines have a trailing space.

differently.

You should keep From: as the same person, keep his Signed-off-by, add
your Signed-off-by and mention what you have changed in the series.

Thanks for re-sending this, btw.

Hans's patches didn't have a S-o-b. I can resend the same patches again
with my S-o-b (I'm fine with doing this without Hans's since I came up with
exactly the same patches independently from Hans) and detailing the changes
from the initial patch. Does that sound good?
