The debugfs file creation has been part of the core initialization
handling of controllers. With the introduction of Bluetooth 4.2 core
specification, the number of debugfs files is increasing even further.

To avoid cluttering the core controller handling, create a separate
file hci_debugfs.c to centralize all debugfs file creation. For now
leave the current files in the core, but in the future all debugfs
file creation will be moved.

Every BR/EDR/LE dual-mode controller requires to have a public address
and so far that has become the identity address and own address. The
only way to change that behavior was with a force_static_address
debugfs option.

However the host can actually disable the BR/EDR part of a dual-mode
controller and turn into a single mode LE controller. In that case
it makes perfect sense for a host to use a chosen static address
instead of the public address.

So if the host disables BR/EDR and configures a static address, then
that static address is used as identity address and own address. If
the host does not configure a static address, then the public address
is used as before.

The cmd_complete callbacks for pending mgmt commands may fail e.g. in

returned to user space in the form of a failed write on the mgmt socket

Each mmap Netlink frame contains a status field which indicates
whether the frame is unused, reserved, contains data or needs to
be skipped. Both loads and stores may not be reordeded and must
complete before the status field is changed and another CPU might
pick up the frame for use. Use an smp_mb() to cover needs of both
types of callers to netlink_set_status(), callers which have been
reading data frame from the frame, and callers which have been
filling or releasing and thus writing to the frame.

The optimization for filtering out extended inquiry results, advertising
reports or scan response data based on provided UUID list has a logic
bug. In case no match is found in the advertising data, the scan
response is ignored and not checked against the filter. This will lead
to events being filtered wrongly.

Change the code to actually only drop the events when the scan response
data is not present. If it is present, it needs to be checked against
the provided filter.

The patch is a bit more complex than it needs to be. That is because
it also fixes this compiler warning that some gcc versions produce.

The NBMA GRE tunnels temporarily push GRE header that contain the
per-packet NBMA destination on the skb via header ops early in xmit
path. It is the later pulled before the real GRE header is constructed.

The inner mac was thus set differently in nbma case: the GRE header
has been pushed by neighbor layer, and mac header points to beginning
of the temporary gre header (set by dev_queue_xmit).

Now that the offloads expect mac header to point to the gre payload,
fix the xmit patch to:
 - pull first the temporary gre header away
 - and reset mac header to point to gre payload

This fixes tso to work again with nbma tunnels.

This patch addresses an issue with the level compression of the fib_trie.
Specifically in the case of adding a new leaf that triggers a new node to
be added that takes the place of the old node.  The result is a trie where
the 1 child tnode is on one side and one leaf is on the other which gives
you a very deep trie.  Below is the script I used to generate a trie on
dummy0 with a 10.X.X.X family of addresses.

  ip link add type dummy
  ipval=184549374
  bit=2
  for i in `seq 1 23`
  do
    ifconfig dummy0:$bit $ipval/8
    ipval=`expr $ipval - $bit`
    bit=`expr $bit \* 2`
  done
  cat /proc/net/fib_triestat

Running the script before the patch:

	Local:
		Aver depth:     10.82
		Max depth:      23
		Leaves:         29
		Prefixes:       30
		Internal nodes: 27
		  1: 26  2: 1
		Pointers: 56
	Null ptrs: 1
	Total size: 5  kB

After applying the patch and repeating:

	Local:
		Aver depth:     4.72
		Max depth:      9
		Leaves:         29
		Prefixes:       30
		Internal nodes: 12
		  1: 3  2: 2  3: 7
		Pointers: 70
	Null ptrs: 30
	Total size: 4  kB

What this fix does is start the rebalance at the newly created tnode
instead of at the parent tnode.  This way if there is a gap between the
parent and the new node it doesn't prevent the new tnode from being
coalesced with any pre-existing nodes that may have been pushed into one
of the new nodes child branches.

When an adapter is removed (hci_unregister_dev) any pending mgmt
commands for that adapter should get the appropriate INVALID_INDEX
response. Since hci_unregister_dev() calls hci_dev_do_close() first
that'd so far have caused "not powered" responses to be sent.

Skipping the HCI_UNREGISTER case in mgmt_powered() is also not a
solution since before reaching the mgmt_index_removed() stage any
hci_conn callbacks (e.g. used by pairing) will get called, thereby
causing "disconnected" status responses to be sent.

The fix that covers all scenarios is to handle both INVALID_INDEX and
NOT_POWERED responses through the mgmt_powered() function. The
INVALID_INDEX response sending from mgmt_index_removed() is left
untouched since there are a couple of places not related to powering off
or removing an adapter that call it (e.g. configuring a new bdaddr).

This patch moves the mgmt_powered() notification earlier in the
hci_dev_do_close() function. This way the correct "not powered" error
gets passed to any pending mgmt commands. Without the patch the pending
commands would instead get a misleading "disconnected" response when
powering down the adapter.

The pairing_complete() function is used as a pending mgmt command
cmd_complete callback. The expectation of such functions is that they
are not responsible themselves for calling mgmt_pending_remove(). This
patch fixes the incorrect mgmt_pending_remove() call in
pairing_complete() and adds it to the appropriate changes.
