Pull apparmor updates from John Johansen:
 "This has one major feature, it pulls in a cleaned up version of
  af_unix mediation that Ubuntu has been carrying for years. It is
  placed behind a new abi to ensure that it does cause policy
  regressions. With pulling in the af_unix mediation there have been
  cleanups and some refactoring of network socket mediation. This
  accounts for the majority of the changes in the diff.

  In addition there are a few improvements providing minor code
  optimizations. several code cleanups, and bug fixes.

  Features:
   - improve debug printing
   - carry mediation check on label (optimization)
   - improve ability for compiler to optimize
     __begin_current_label_crit_section
   - transition for a linked list of rulesets to a vector of rulesets
   - don't hardcode profile signal, allow it to be set by policy
   - ability to mediate caps via the state machine instead of lut
   - Add Ubuntu af_unix mediation, put it behind new v9 abi

  Cleanups:
   - fix typos and spelling errors
   - cleanup kernel doc and code inconsistencies
   - remove redundant checks/code
   - remove unused variables
   - Use str_yes_no() helper function
   - mark tables static where appropriate
   - make all generated string array headers const char *const
   - refactor to doc semantics of file_perm checks
   - replace macro calls to network/socket fns with explicit calls
   - refactor/cleanup socket mediation code preparing for finer grained
     mediation of different network families
   - several updates to kernel doc comments

  Bug fixes:
   - fix incorrect profile->signal range check
   - idmap mount fixes
   - policy unpack unaligned access fixes
   - kfree_sensitive() where appropriate
   - fix oops when freeing policy
   - fix conflicting attachment resolution
   - fix exec table look-ups when stacking isn't first
   - fix exec auditing
   - mitigate userspace generating overly large xtables"
