This patch adds a callback for VIDIOCSWIN ioctl to usbvideo so
the webcam miniport drivers can implement handling for the ioctl.

It also makes VIDIOCGWIN return the frame size for the current
mode rather than the canvas size. For current drivers
uvd->canvas == uvd->videosize since the frame size is set
when the module is loaded.

Whoops!  Accidentally introduced a typo.  This patch should fix the typo...
it's designed to apply after the last one.

This should be the final patch to make the abort mechanisms work properly.

Another cleanup patch:

   - removes more usbcore-internal symbols from sight of device drivers
       * some are only for the uhci driver
       * most are shared just a bit more widely
   - DEVNUM_ROUND_ROBIN is no longer an internal option
   - usb_root_hub_string() gone, per the FIXME
   - various kerneldoc fixes and updates
   - uses legal value (en-us) for root hub strings
   - hub driver only shows port fixed/removable for compound devices

        this fixes HP's vendor ID in ipaq.h

This patch presents the snapshot button on the camera as an
event input device.

This patch against 2.5.31 cleans up the RingQueue_* functions

- make the buffer length be a power of 2 to speed up index manipulation
- make RingQueue_Dequeue use memcpy() rather than a byte by byte copy
- make RingQueue_Enqueue use memcpy() instead of memmove() as the memory
  regions do not overlap
- Add RingQueue_Flush() and RingQueue_GetFreeSpace()
- make RingQueue_GetLength() an inline

This is the second part of "broken cfb* support in the 2.5.31-bk".  I
needed fbcon-cfb2 on one of my systems, and so I went through all
fbcon-* drivers and fixed them.

line_length, type, type_aux and visual were moved from display to
fb_info in last James Simmon's fbdev update.  Unfortunately lowlevel
support modules were not updated.

I want to find a way to get all those PageReserved tests out of
there, because they are very expensive.  But now is not the
time.

Make sure that the VC tty pointer is cleared when the tty is free'd.

bit of cleaning later.

a bit later

Note: I've also fixed several obvious "forgot to update" problems (changed
prototype of blk_init_queue(), etc.) but I hadn't touched the DMA-mapping
stuff, so it still doesn't work with 2.5; moreover, it misses a lot of fixes
done in 2.4, but that's fun for Alan - he's the maintainer

Well I didn't test that very well.  __page_cache_release() is doing a
__free_page() on a zero-ref page, so __free_pages() sends the refcount
negative and doesn't free it.  With patch #8, page_cache_release()
almost never frees pages, but it must have been leaking a little bit.
Lucky it showed up.

This fixes it, and also adds a missing PageReserved test in put_page().
Which makes put_page() identical to page_cache_release(), but there are
header file woes.  I'll fix that up later.

This trivial patch reorders the unlocking in rq_unlock()... I was
tired of getting stack dumps in my messages file.

isn't ready for it (either during early boot, or at shutdown)
