If a master would like to raise the security level, it will send a
pairing request. While the pending security level is set on an incoming
security request (from a slave), it is not set on a pairing request. As
a result, the security level would not be raised on the slave in such
case.
Fix this by setting the pending security when receiving pairing
requests according to the requested authorization.

This rips the message queue in the PL022 driver out and pushes
it into (optional) common infrastructure. Drivers that want to
use the message pumping thread will need to define the new
per-messags transfer methods and leave the deprecated transfer()
method as NULL.
Most of the design is described in the documentation changes that
are included in this patch.
Since there is a queue that need to be stopped when the system
is suspending/resuming, two new calls are implemented for the
device drivers to call in their suspend()/resume() functions:
spi_master_suspend() and spi_master_resume().
ChangeLog v1->v2:
- Remove Kconfig entry and do not make the queue support optional
at all, instead be more agressive and have it as part of the
compulsory infrastructure.
- If the .transfer() method is implemented, delete print a small
deprecation notice and do not start the transfer pump.
- Fix a bitrotted comment.
ChangeLog v2->v3:
- Fix up a problematic sequence courtesy of Chris Blair.
- Stop rather than destroy the queue on suspend() courtesy of
Chris Blair.

When destroying a listening cmid, the iwcm first marks the state of
the cmid as DESTROYING, then releases the lock and calls into the
iWARP provider to destroy the endpoint. Since the cmid is not locked,
its possible for the iWARP provider to pass a connection request event
to the iwcm, which will be silently dropped by the iwcm. This causes
the iWARP provider to never free up the resources from this connection
because the assumption is the iwcm will accept or reject this connection.
The solution is to reject these connection requests.

This patch splits the DMM off into a separate sub-device, in order to
utilize the platform device information that was created as part of
the OMAP hwmod entry for the DMM.
The driver probe function queries the iomem resource and IRQ using
standard platform_get functions.
The OMAP DRM driver now calls the platform_driver_register() function
for the subordinate DMM driver inside its probe function. This
guarantees the required order for the DMM and ensures the DMM resources
are available for use by the DRM driver.

tsl2563 probe function has two minor issues with it's error handling paths:
1) it is silent (did not report errors to dmesg)
2) did not return failure code (mixed up use of ret and err)
and two major issues:
3) goto fail2 would corrupt a free memory pool ("double free")
4) device registration failure did NOT cancel/flush delayed work.
(and thus dereference a freed data structure later)
The "double free" is subtle and was introduced with this change:
Author: Jonathan Cameron <jic23@cam.ac.uk>
Date: Mon Apr 18 12:58:55 2011 +0100
staging:iio:tsl2563 take advantage of new iio_device_allocate private data.
Originally, chip was allocated seperately. Now it's appended to the
indio_dev by iio_allocate_device(sizeof(*chip)). So we only need one
kfree call as well (in iio_free_device()).
Gory details of tracking this down are here:
http://crosbug.com/26819
Despite iio_device_registration failing, system can at least now boot.
Will follow up with a fix to "double register : in_intensity_both_raw"

The lowmemorykiller registers an atomic notifier for notfication of when
the task is freed. From this atomic notifier callback, it removes the
atomic notifier via task_free_unregister(). This is incorrect because
atomic_notifier_chain_unregister() calls syncronize_rcu(), which can
sleep, which shouldn't be done from an atomic notifier.
Fix this by registering the notifier during init, and only unregister it
if the lowmemorykiller is unloaded.
