This update gets things compiling again after a device model change.

This adds preliminary support for _TRA resource on PCI root bridges (Bjorn
Helgaas)

end_request(int) turned to end_request(req, int); all old callers
are converted to end_request(CURRENT, value).  Now we can start
killing CURRENT/QUEUE - end_request() was the last obstacle to
that.

ditto for DEVICE_INTR/CLEAR_INTR.  do_mfm/do_acsi/do_hd/... are
explicitly declared in the drivers that use DEVICE_INTR stuff;
DEVICE_INTR/CLEAR_INTR is gone from blk.h.

#define DEVICE_NAME ... removed from the drivers that never use
that macro.

monstrous cascade of #ifdefs is gone from blk.h.  This is the first
step of cleanup - we move #define in question into the code that
includes blk.h (i.e. DEVICE_NR, DEVICE_NAME and DEVICE_INTR are
explicitly set by drivers).

->s_dev is switched to dev_t.  Everything that uses it uses it as
a number - i.e. all instances are either minor() or kdev_t_to_nr().

->j_dev is gone from reiserfs journal.  All its uses had been replaced
with use of ->j_dev_bd; it's simply not used anymore.

get_super() split in two functions - get_super(bdev) and
user_get_super(dev_t).  Callers that used get_super() to get superblock
by (dev_t) syscall argument switched to the latter; the rest had
block_device in question and switched to passing it.

ROOT_DEV converted to dev_t.  There's no reason for it to be kdev_t -
it's both used as a number and set as a number.

do_getattr() renamed to vfs_getattr(), exported and used by
loop.c and nfsd - both blindly accessed ->i_dev/->i_ino of
random inodes when they ought to be calling ->getattr() to
get that information.

misc gratitious kdev_t uses fixed (janitorial stuff - e.g. quota
patches had reintroduced kdevname(sb->s_dev) in places where we'd
switched to sb->s_id, etc.)

added bdev_read_only() - analog of is_read_only() using block_device.
Almost all callers of is_read_only() converted.

sget()/generic_shutdown_super() cleaned up; fixed error handling
in sget()

FS_NOMOUNT is gone, initialization for pseudo-filesystems
(bdev, pipe, sock) switched to use of a common helper.

compile fixes (missing includes + obvious fix in adfs/map.c)

pay attention to the return value of usb_control_msg as found by the CHECKER tool.

pay attention to return value of usb_submit_urb as found by the CHECKER tool.

This is a collected patch for USB drivers to use the new list macros
(list_del_init, list_move*).

 - Sync with 2.5.21

 - Don't call put_device inside idedisk_cleanup(). This is apparently triggering
   some bug inside the handling of device trees. Or we don't register the device
   properly within the tree. Check this later.

 - Further work on the channel register file access locking.  Push the locking
   out from __ide_end_request to ide_end_request.  Rename those functions to
   respective __ata_end_request() and ata_end_request().

 - Move ide_wait_status to device.c rename it to ata_status_poll().

 - Further work on locking scope issues.

 - devfs showed us once again that it changed the policy from agnostic numbers
   to unpleasant string names.

The subject says it all...

Contrary to other proposed patches I realized that there is
no such thing as vmalloc_dma.

This does a little optimisation, namely kill an unneeded counter
and put the members of the device descriptor structure in an order
that should be a little more efficient.

DEVICE_ID_SIZE clashes with the define in include/linux/device.h

Need asm/irq.h too...

Need asm/io.h if you want to use ioremap() et al.

This patch fixes a highmem issue with ns83820.c when used with the
pci dma fix for x86.  The patch was successfully tested on a highmem
machine with 5GB of ram and a file in high memory.  Cruft from the
pre-64 bit pci dma era is also removed.

This is the same patch as was posted against 2.4.19-pre10: pci_map_page
was missing a cast on x86, which resulted in the high 32 bits of an
address being silently discarded.  This patch fixes that by casting
the page number before multiplying it out.

- Delays or eliminates some IRQs  It'll mostly affect control
   or iso transfers, which typically have multiple TDs per URB,
   by making only the last TD generate an IRQ.

- Shortens some of the submit path that needs to run with
   IRQs disabled ... no need to use the dma_to_td hashtable.
   (Of course that path is still pretty long...)

- Gets rid of case where the ED state was confused ... now
   there's only one such state, not two.

Attached you'll find a patch for the Philips Webcam Driver version 8.7.
This is a jump from 8.5, since 8.6 never officially made it into the 2.5
series due to rapid changes and incompatabilities.

The biggest changes include (from the Changelog)

8.7

* Incorporating changes in ioctl() parameter passing
* Also changes to URB mechanism
* Updating copyright information

8.6

* Added ID's for Visionite VCS UM100 and UC300
* Removed YUV420-interlaced palette altogether (was confusing)
* Removed MIRROR stuff as it didn't work anyway
* Fixed a problem with the 'leds' parameter (wouldn't blink)
* Added ioctl()s for advanced features: 'extended' whitebalance ioctl()s,
  CONTOUR, BACKLIGHT, FLICKER, DYNNOISE.
* VIDIOCGCAP.name now contains real camera model name instead of
  'Philips xxx webcam'
* Added PROBE ioctl (see previous point & API doc)

One could get to like "KBUILD_VERBOSE=0 make" ... :)

This gets rid of a compile warning.
