Subject: [PATCH 0/7] caching bundles, iteration 2

This is the current dump of my working tree. The first three
patches should be good already.

The patches 4-7 are more of experimental. And patch 6 has
currently a "bundle leak". If we have per-socket policy that
results in requiring a bundle, it's never freed. I'm not yet
exactly sure how to deal with that. Probably should keep the
bundles not associated with a flow cache entry in their own
global list, which should get garbage collected periodically.

Timo Teras (7):
  xfrm: remove policy lock when accessing policy->walk.dead
  flow: structurize flow cache
  flow: allocate hash table for online cpus only
  flow: delayed deletion of flow cache entries
  flow: virtualize get and entry deletion methods
  xfrm: cache bundles instead of policies for outgoing flows
  xfrm: remove policy garbage collection
