Does this patch have to be reverted in 3.10 as well ? Linus' e-mail seems to
suggest it, but Shuah didn't see the problem there.  I ran a quick test with
3.10.8 on an x86 system and did not see a problem either, at least not
immediately. 

I want to add some networking to my qemu tests, but it would help to know how
to catch such errors automatically ... that is, if there is a way to do that.
