Staging: remove wusbcore and UWB from the kernel tree.

It's been over 6 months, and no one has noticed that these drivers are
deleted, probably because no one actually has this hardware.  As no one
has volunteered to maintain the code, let's drop it for good.

-	select GENERIC_NET_UTILS
-	help
-	  UWB is a high-bandwidth, low-power, point-to-point radio
-	  technology using a wide spectrum (3.1-10.6GHz). It is
-	  optimized for in-room use (480Mbps at 2 meters, 110Mbps at
-	  10m). It serves as the transport layer for other protocols,
-	  such as Wireless USB (WUSB).
-
-	  The topology is peer to peer; however, higher level
-	  protocols (such as WUSB) might impose a master/slave
-	  relationship.
-
-	  Say Y here if your computer has UWB radio controllers (USB or PCI)
-	  based. You will need to enable the radio controllers
-	  below.  It is ok to select all of them, no harm done.
-
-	  For more help check the UWB and WUSB related files in
-	  <file:Documentation/usb/>.
-
-	  To compile the UWB stack as a module, choose M here.

-	help
-	  This driver enables the radio controller for HWA USB
-	  devices. HWA stands for Host Wire Adapter, and it is a UWB
-	  Radio Controller connected to your system via USB. Most of
-	  them come with a Wireless USB host controller also.
-
-	  To compile this driver select Y (built in) or M (module). It
-	  is safe to select any even if you do not have the hardware.

-        depends on PCI
-        help
-          This driver enables the radio controller for WHCI cards.
-
-          WHCI is a specification developed by Intel
-          (http://www.intel.com/technology/comms/wusb/whci.htm) much
-          in the spirit of USB's EHCI, but for UWB and Wireless USB
-          radio/host controllers connected via memory mapping (eg:
-          PCI). Most of these cards come also with a Wireless USB host
-          controller.
-
-          To compile this driver select Y (built in) or M (module). It
-          is safe to select any even if you do not have the hardware.

-        help
-         This driver enables support for the i1480 when connected via
-         USB. It consists of a firmware uploader that will enable it
-         to behave as an HWA device.

- *
- * Because USB and PCI use common methods, we just make ops out of the
- * common operations (read, write, wait_init_done and cmd) and
- * implement them in usb.c and pci.c.

- *
- * UMC (UWB Multi-interface Controller) capabilities (e.g., radio

- * bus.
- *
- * The radio controller is not strictly a UMC capability but it's

- * References:
- *
- *   [WHCI] Wireless Host Controller Interface Specification for

- *
- * How this works is kind of convoluted but simple. The whci.ko driver
- * loads when WHCI devices are detected. These WHCI devices expose
- * many devices in the same PCI function (they couldn't have reused
- * functions, no), so for each PCI function that exposes these many
- * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
- * with umc_device_create() and adds it to the bus with
- * umc_device_register().
- *
- * umc_device_register() calls device_register() which will push the
- * bus management code to load your UMC driver's somehting_probe()
- * that you have registered for that capability code.
- *
- * Now when the WHCI device is removed, whci_remove() will go over
- * each umc_dev assigned to each of the PCI function's capabilities
- * and through whci_del_cap() call umc_device_unregister() each
- * created umc_dev. Of course, if you are bound to the device, your
- * driver's something_remove() will be called.

- * WUSB Wire Adapter: Radio Control Interface (WUSB[8])
- * Notification and Event Handling
- *
- * Copyright (C) 2005-2006 Intel Corporation
- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *
- * The RC interface of the Host Wire Adapter (USB dongle) or WHCI PCI
- * card delivers a stream of notifications and events to the
- * notification end event endpoint or area. This code takes care of
- * getting a buffer with that data, breaking it up in separate
- * notifications and events and then deliver those.
- *
- * Events are answers to commands and they carry a context ID that
- * associates them to the command. Notifications are that,
- * notifications, they come out of the blue and have a context ID of
- * zero. Think of the context ID kind of like a handler. The
- * uwb_rc_neh_* code deals with managing context IDs.
- *
- * This is why you require a handle to operate on a UWB host. When you
- * open a handle a context ID is assigned to you.
- *
- * So, as it is done is:
- *
- * 1. Add an event handler [uwb_rc_neh_add()] (assigns a ctx id)
- * 2. Issue command [rc->cmd(rc, ...)]
- * 3. Arm the timeout timer [uwb_rc_neh_arm()]
- * 4, Release the reference to the neh [uwb_rc_neh_put()]
- * 5. Wait for the callback
- * 6. Command result (RCEB) is passed to the callback
- *
- * If (2) fails, you should remove the handle [uwb_rc_neh_rm()]
- * instead of arming the timer.
- *
- * Handles are for using in *serialized* code, single thread.
- *
- * When the notification/event comes, the IRQ handler/endpoint
- * callback passes the data read to uwb_rc_neh_grok() which will break
- * it up in a discrete series of events, look up who is listening for
- * them and execute the pertinent callbacks.
- *
- * If the reader detects an error while reading the data stream, call
- * uwb_rc_neh_error().
- *
- * CONSTRAINTS/ASSUMPTIONS:
- *
- * - Most notifications/events are small (less thank .5k), copying
- *   around is ok.
- *
- * - Notifications/events are ALWAYS smaller than PAGE_SIZE
- *
- * - Notifications/events always come in a single piece (ie: a buffer
- *   will always contain entire notifications/events).
- *
- * - we cannot know in advance how long each event is (because they
- *   lack a length field in their header--smart move by the standards
- *   body, btw). So we need a facility to get the event size given the
- *   header. This is what the EST code does (notif/Event Size
- *   Tables), check nest.c--as well, you can associate the size to
- *   the handle [w/ neh->extra_size()].
- *
- * - Most notifications/events are fixed size; only a few are variable
- *   size (NEST takes care of that).
- *
- * - Listeners of events expect them, so they usually provide a
- *   buffer, as they know the size. Listeners to notifications don't,
- *   so we allocate their buffers dynamically.

- * @rc:	      UWB Radio Controller
- * @buf:      Buffer with the stream of notifications/events
- * @buf_size: Amount of data in the buffer
- *
- * Note each notification/event starts always with a 'struct
- * uwb_rceb', so the minimum size if 4 bytes.
- *
- * The device may pass us events formatted differently than expected.
- * These are first filtered, potentially creating a new event in a new
- * memory location. If a new event is created by the filter it is also
- * freed here.
- *
- * For each notif/event, tries to guess the size looking at the EST
- * tables, then looks for a neh that is waiting for that event and if
- * found, copies the payload to the neh's buffer and calls it back. If
- * not, the data is ignored.
- *
- * Note that if we can't find a size description in the EST tables, we
- * still might find a size in the 'neh' handle in uwb_rc_neh_lookup().
- *
- * Assumptions:
- *
- *   @rc->neh_lock is NOT taken
- *
- * We keep track of various sizes here:
- * size:      contains the size of the buffer that is processed for the
- *            incoming event. this buffer may contain events that are not
- *            formatted as WHCI.
- * real_size: the actual space taken by this event in the buffer.
- *            We need to keep track of the real size of an event to be able to
- *            advance the buffer correctly.
- * event_size: the size of the event as expected by the core layer
- *            [OR] the size of the event after filtering. if the filtering
- *            created a new event in a new memory location then this is
- *            effectively the size of a new event buffer

-/**
- * UWB radio controller Event Size Entry (for creating entry tables)
- *
- * WUSB and WHCI define events and notifications, and they might have
- * fixed or variable size.
- *
- * Each event/notification has a size which is not necessarily known
- * in advance based on the event code. As well, vendor specific
- * events/notifications will have a size impossible to determine
- * unless we know about the device's specific details.
- *
- * It was way too smart of the spec writers not to think that it would
- * be impossible for a generic driver to skip over vendor specific
- * events/notifications if there are no LENGTH fields in the HEADER of
- * each message...the transaction size cannot be counted on as the
- * spec does not forbid to pack more than one event in a single
- * transaction.
- *
- * Thus, we guess sizes with tables (or for events, when you know the
- * size ahead of time you can use uwb_rc_neh_extra_size*()). We
- * register tables with the known events and their sizes, and then we
- * traverse those tables. For those with variable length, we provide a
- * way to lookup the size inside the event/notification's
- * payload. This allows device-specific event size tables to be
- * registered.
- *
- * @size:   Size of the payload
- *
- * @offset: if != 0, at offset @offset-1 starts a field with a length
- *          that has to be added to @size. The format of the field is
- *          given by @type.
- *
- * @type:   Type and length of the offset field. Most common is LE 16
- *          bits (that's why that is zero); others are there mostly to
- *          cover for bugs and weirdos.

- * Neighborhood Management Daemon
- *
- * Copyright (C) 2005-2006 Intel Corporation
- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *
- * This daemon takes care of maintaing information that describes the
- * UWB neighborhood that the radios in this machine can see. It also
- * keeps a tab of which devices are visible, makes sure each HC sits
- * on a different channel to avoid interfering, etc.
- *
- * Different drivers (radio controller, device, any API in general)
- * communicate with this daemon through an event queue. Daemon wakes
- * up, takes a list of events and handles them one by one; handling
- * function is extracted from a table based on the event's type and
- * subtype. Events are freed only if the handling function says so.
- *
- *   . Lock protecting the event list has to be an spinlock and locked
- *     with IRQSAVE because it might be called from an interrupt
- *     context (ie: when events arrive and the notification drops
- *     down from the ISR).
- *
- *   . UWB radio controller drivers queue events to the daemon using
- *     uwbd_event_queue(). They just get the event, chew it to make it
- *     look like UWBD likes it and pass it in a buffer allocated with
- *     uwb_event_alloc().
- *
- * EVENTS
- *
- * Events have a type, a subtype, a length, some other stuff and the
- * data blob, which depends on the event. The header is 'struct
- * uwb_event'; for payloads, see 'struct uwbd_evt_*'.
- *
- * EVENT HANDLER TABLES
- *
- * To find a handling function for an event, the type is used to index
- * a subtype-table in the type-table. The subtype-table is indexed
- * with the subtype to get the function that handles the event. Start
- * with the main type-table 'uwbd_evt_type_handler'.
- *
- * DEVICES
- *
- * Devices are created when a bunch of beacons have been received and
- * it is stablished that the device has stable radio presence. CREATED
- * only, not configured. Devices are ONLY configured when an
- * Application-Specific IE Probe is receieved, in which the device
- * declares which Protocol ID it groks. Then the device is CONFIGURED
- * (and the driver->probe() stuff of the device model is invoked).
- *
- * Devices are considered disconnected when a certain number of
- * beacons are not received in an amount of time.
- *
- * Handler functions are called normally uwbd_evt_handle_*().
