Linus Torvalds dab363f938 Staging patches for 3.19-rc1
Here's the big staging tree pull request for 3.19-rc1.
 
 We continued to delete more lines than were added, always a good thing,
 but not at a huge rate this release, only about 70k lines removed
 overall mostly from removing the horrid bcm driver.
 
 Lots of normal staging driver cleanups and fixes all over the place,
 well over a thousand of them, the shortlog shows all the horrid details.
 
 The "contentious" thing here is the movement of the Android binder code
 out of staging into the "real" part of the kernel.  This is code that
 has been stable for a few years now and is working as-is in the tens of
 millions of devices with no issues.  Yes, the code is horrid, and the
 userspace api leaves a lot to be desired, but it's not going to change
 due to legacy issues that we have no control over.  Because so many
 devices and companies rely on this, and the code is stable, might as
 well promote it out of staging.
 
 This was all discussed at the Linux Plumbers conference, and everyone
 participating agreed that this was the best way forward.
 
 There is work happening to replace the binder code with something new
 that is happening right now, but I don't expect to see the results of
 that work for another year at the earliest.  If that ever happens, and
 Android switches over to it, I'll gladly remove this version.
 
 As for maintainers, I'll be glad to maintain this code, I've been doing
 it for the past few years with no problems.  I'll send a MAINTAINERS
 entry for it before 3.19-final is out, still need to talk to the Google
 developers about if they are willing to help with it or not, last I
 checked they were, which was good.
 
 All of these patches have been in linux-next for a while with no
 reported issues.

OZWPAN USB Host Controller Driver
---------------------------------
This driver is a USB HCD driver that does not have an associated a physical
device but instead uses Wi-Fi to communicate with the wireless peripheral.
The USB requests are converted into a layer 2 network protocol and transmitted
on the network using an ethertype (0x892e) regestered to Ozmo Device Inc.
This driver is compatible with existing wireless devices that use Ozmo Devices
technology.

To operate the driver must be bound to a suitable network interface. This can
be done when the module is loaded (specifying the name of the network interface
as a parameter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after
loading using an ioctl call. See the ozappif.h file and the ioctls
OZ_IOCTL_ADD_BINDING and OZ_IOCTL_REMOVE_BINDING.

The devices connect to the host use Wi-Fi Direct so a network card that supports
Wi-Fi direct is required. A recent version (0.8.x or later) version of the
wpa_supplicant can be used to setup the network interface to create a persistent
autonomous group (for older pre-WFD peripherals) or put in a listen state to
allow group negotiation to occur for more recent devices that support WFD.

The protocol used over the network does not directly mimic the USB bus
transactions as this would be rather busy and inefficient. Instead the chapter 9
requests are converted into a request/response pair of messages. (See
ozprotocol.h for data structures used in the protocol).
