Following the programming advice laid down in the gcc manual, make
sure the case "..." operator has spaces on either side.

According to:

http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Case-Ranges.html#Case-Ranges:

  "Be careful: Write spaces around the ..., for otherwise it may be
parsed wrong when you use it with integer values."

Switch cb_lock to mutex and allow netlink kernel users to override it
with a subsystem specific mutex for consistent locking in dump callbacks.
All netlink_dump_start users have been audited not to rely on any
side-effects of the previously used spinlock.

For the common "(struct nlmsghdr *)skb->data" sequence, so that we reduce the
number of direct accesses to skb->data and for consistency with all the other
cast skb member helpers.

So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

The following patch adds a new mode to the audit system. It uses the
audit_enabled config option to introduce the idea of audit enabled, but
configuration is immutable. Any attempt to change the configuration
while in this mode is audited. To change the audit rules, you'd need to
reboot the machine.

To use this option, you'd need a modified version of auditctl and use "-e 2".
This is intended to go at the end of the audit.rules file for people that
want an immutable configuration.

This patch also adds "res=" to a number of configuration commands that did not
have it before.

Move process freezing functions from include/linux/sched.h to freezer.h, so
that modifications to the freezer or the kernel configuration don't require
recompiling just about everything.

Squash this warning:

  kernel/audit.c: In function 'kauditd_thread':
  kernel/audit.c:367: warning: no return statement in function returning non-void

We might as test kthread_should_stop(), although it's not very pointful at
present.

The code which starts this thread looks racy - the kernel could start multiple
threads.
