====================
ipset patches for nf

Please apply the next patches for ipset in your nf branch.
Both patches should go into the stable kernel branches as well,
because these are important bugfixes:

* Sometimes valid entries in hash:* types of sets were evicted
  due to a typo in an index. The wrong evictions happen when
  entries are deleted from the set and the bucket is shrinked.
  Bug was reported by Eric Ewanco and the patch fixes
  netfilter bugzilla id #1119.
* Fixing of a null pointer exception when someone wants to add an
  entry to an empty list type of set and specifies an add before/after
  option. The fix is from Vishwanath Pai.
