[PATCHSET] audit fixes

[Al Viro <viro@ftp.linux.org.uk>]

Linus, please pull audit fixes from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/audit-current.git/ audit.b10

This stuff had been sitting in -mm for weeks now and fixes a bunch of bugs -
both performance (killing serious unnecessary overhead) and outright leaks
and deadlocks.

Shortlog:

Al Viro:
      deal with deadlocks in audit_free()
      move call of audit_free() into do_exit()
      drop gfp_mask in audit_log_exit()
      drop task argument of audit_syscall_{entry,exit}
      no need to wank with task_lock() and pinning task down in audit_syscall_exit()

Darrel Goeddel:
      support for context based audit filtering
      support for context based audit filtering, part 2

Steve Grubb:
      sockaddr patch
      audit inode patch
      change lspp ipc auditing
      Reworked patch for labels on user space messages
      More user space subject labels
      Rework of IPC auditing
      Audit Filter Performance
