[Davide Italiano]

Author: davide
Date: Thu Nov 22 09:13:45 2012
New Revision: 243397
URL: http://svnweb.freebsd.org/changeset/base/243397

Log:
  - Remove reset of vpp pointer in some places as long as it's not really
  useful and has the side effect of obfuscating the code a bit.
  - Remove spurious references to simple_lock.
