Well, keep in mind I reproduced the swapops bug with 2.6.33 anon-vma
code, it's unlikely that focusing on patch 2 you'll fix bug in
swapops.h. If this is a bug in the new anon-vma code, it needs fixing
of course! But I doubt this bug is related to swapops in execve on the
bprm->p args.

I've yet to check in detail patch 1 sorry, I'll let you know my
opinion about it as soon as I checked it in detail.
