For the lguest patch, Rusty is the maintainer and has already acked the 
patch, so I think it should be merged through him.  I don't see a need for 
the second patch since we'll now detect frozen oom killed tasks on retry 
and don't need to kill them directly when oom killed (it just adds 
additional, unnecessary code).

If that's possible, then we can just add Tejun to add a follow-up patch to 
remove the thaw directly in the oom killer.  I'm thinking that won't be 
possible for 3.2, though, so I don't know why we'd remove 
oom-thaw-threads-if-oom-killed-thread-is-frozen-before-deferring.patch 
from -mm?
