<title>kernel: Map most files to use export.h instead of module.h</title>

The changed files were only including linux/module.h for the
EXPORT_SYMBOL infrastructure, and nothing else.  Revector them
onto the isolated export header for faster compile times.

Nothing to see here but a whole lot of instances of:

  -#include &lt;linux/module.h&gt;
  +#include &lt;linux/export.h&gt;

This commit is only changing the kernel dir; next targets
will probably be mm, fs, the arch dirs, etc.

This allows us to move duplicated code in &lt;asm/atomic.h&gt;
(atomic_inc_not_zero() for now) to &lt;linux/atomic.h&gt;

<title>audit: acquire creds selectively to reduce atomic op overhead</title>

Commit c69e8d9c01db ("CRED: Use RCU to access another task's creds and to
release a task's own creds") added calls to get_task_cred and put_cred in
audit_filter_rules.  Profiling with a large number of audit rules active
on the exit chain shows that we are spending upto 48% in this routine for
syscall intensive tests, most of which is in the atomic ops.

1. The code should be accessing tsk-&gt;cred rather than tsk-&gt;real_cred.
2. Since tsk is current (or tsk is being created by copy_process) access to
tsk-&gt;cred without rcu read lock is possible.  At the request of the audit
maintainer, a new flag has been added to audit_filter_rules in order to make
this explicit and guide future code.

Normal syscall audit doesn't catch 5th argument of syscall.  It also
doesn't catch the contents of userland structures pointed to be
syscall argument, so for both old and new mmap(2) ABI it doesn't
record the descriptor we are mapping.  For old one it also misses
flags.

The name is long and it serves no real purpose.  So rename
fsnotify_mark_entry to just fsnotify_mark.

Simply switch audit_trees from using inotify to using fsnotify for it's
inode pinning and disappearing act information.

with minimal code changes for easy review.  Now fix interfaces to make
