Needs a Signed-off-by line. Also please use "[PATCH]" instead of
"PATCH:" in the subject line so that git am automatically removes it
when applying the patch. You get a correctly formatted mail with git
format-patch.

And yes, your mailer has broken the patch, so adding the attachment was
a good idea (using git send-email would be even better, though).

qemu uses four spaces for indentation, tabs are not allowed. Also, a \
at the end of a line is not needed.

The logic of the patch looks okay, so please send a v2 with just these
formal things fixed.
