Before implementing SM key distribution, the pairing features
exchange must be better negotiated, taking into account some
features of the host and connection requirements.

If we are in the "not pairable" state, it makes no sense to
exchange any key. This allows for simplification of the key
negociation method.

As the LTK (the new type of key being handled now) has more data

The ERTM receive buffer is now handled in a way that does not require

This change moves most L2CAP ERTM receive buffer handling out of the
L2CAP core and in to the socket code.  It's up to the higher layer
(the socket code, in this case) to tell the core when its buffer is
full or has space available.  The recv op should always accept
incoming ERTM data or else the connection will go down.

Within the socket layer, an skb that does not fit in the socket
receive buffer will be temporarily stored.  When the socket is read
from, that skb will be placed in the receive buffer if possible.  Once
adequate buffer space becomes available, the L2CAP core is informed
and the ERTM local busy state is cleared.

Receive buffer management for non-ERTM modes is unchanged.

The local busy state is entered and exited based on buffer status in

Since hdev->lock may be acquired by threads runnning in interrupt
context, all threads running in process context should disable
local bottom halve before locking hdev->lock. This can be done by
using hci_dev_lock_bh macro.

This way, we avoid potencial deadlocks like this one reported by
CONFIG_PROVE_LOCKING=y.

space.

Convert the current BT_INFO and BT_ERR macros to use bt_printk.
Remove __func__ from BT_ERR macro (and the uses).
Prefix "Bluetooth: " to BT_ERR
Remove __func__ from BT_DBG as function can be prefixed when
using dynamic_debug.

Recent changes to hci_core.c use crypto interfaces, so select CRYPTO
to make sure that those interfaces are present.

Fixes these build errors when CRYPTO is not enabled:

Caused by commit d22ef0bc ("Bluetooth: Add LE SMP Cryptoolbox
functions").  Missing include file, presumably.  This batch has been in
the bluetooth tree since June 14, so it may have been exposed by the
removal of linux/mm.h from netdevice.h ...

Two functions in ssb are using register_pci_controller() which is
__devinit. The functions ssb_pcicore_init_hostmode() and
ssb_gige_probe() should also be __devinit.

This fixes the following warning:
WARNING: vmlinux.o(.text+0x2727b8): Section mismatch in reference from the function ssb_pcicore_init_hostmode() to the function .devinit.text:register_pci_controller()
The function ssb_pcicore_init_hostmode() references
the function __devinit register_pci_controller().
This is often because ssb_pcicore_init_hostmode lacks a __devinit
annotation or the annotation of register_pci_controller is wrong.

WARNING: vmlinux.o(.text+0x273398): Section mismatch in reference from the function ssb_gige_probe() to the function .devinit.text:register_pci_controller()
The function ssb_gige_probe() references
the function __devinit register_pci_controller().
This is often because ssb_gige_probe lacks a __devinit
annotation or the annotation of register_pci_controller is wrong.

The patch adds a callback to ath9k_platform_data. If the
callback is provided by the platform code, then it can be
used to hard reset the WMAC device.

The callback is required for doing a hard reset of the AR9330
chips to get them working again after a hang.
