scanners.

Added vendor/product ids for Canon, HP, Microtek, Mustek, Siemens,

This fixes a memory leak in the uniform cdrom layer.

From Szombathelyi György

This fixes a problem where the residual data count isn't being set
correctly.

Real conversion to 32bit dev_t.  Expansion to:
	* mknod() - 32
	* newstat() - 32 on 64bit platforms
	* stat64() - 32 on mips, 64 on everything else (mips has weird struct
stat64 and can't get more than 32 bits).  Note that right now the difference
is purely theoretical - we don't have internal values above 32 bits, so
huge_... vs. new_... only marks the places where 64bit conversion will need
extra work.
	* arch-dependent stat variants - depending on width available.
	* ustat et.al. - 32
	* filesystems that can handle 32 bits right now - 32
	* ext2 and ext3 - 32, with large dev_t inodes having 0 in the first
element of i_data[] (where we store dev_t value for small device numbers) and
keeping the value in the second element.
	* nfsd - 32; it can be driven to 64, but we'll get several issues with
NFSv2 support.
	* RAID - 32
	* devmapper - with v1 it's still 16 (nothing to do here), with v4 it's
64.
	* loop - 64
	* initramfs - 32
	* do_mounts code - 32.  Parts that scan devfs tree are using newstat()
on 64bit platforms and stat64() on the rest (IOW, the latest stat variant on
given platform).
	* old_valid_dev()/new_valid_dev() added where needed (stat variants,
mostly - we fail with -EOVERFLOW if values do not fit).

Starting the conversion:
	* internal dev_t made 32bit.
	* new helpers - new_encode_dev(), new_decode_dev(), huge_encode_dev(),
huge_decode_dev(), new_valid_dev().  They do encoding/decoding of 32bit and
64bit values; for now huge_... are aliases for new_... and new_valid_dev()
is always true.  We do 12:20 for 32bit; representation is compatible with
16bit one - we have major in bits 19--8 and minor in 31--20,7--0.  That's
what the userland sees; internally we have (major << 20)|minor, of course.
	* MKDEV(), MAJOR() and MINOR() updated.
	* several places used to handle Missed'em'V dev_t (14:18 split)
manually; that stuff had been taken into common helpers.
	Now we can start replacing old_... with new_... and huge_..., depending
on the width available.  MKDEV() callers should (for now) make sure that major
and minor are within 12:20.  That's what the next chunk will do.

	Added old_encode_dev() to assorted stat() variants.
	Fixed bug in s390 emulation on s390x: stat64() should never truncate
UID and GID.
	Ditto for i386 emulation on x86_64.
	Replaced dev_t in various struct stat with explicit integer type.
	Replaced __kernel_dev_t with __old_kernel_dev_t in dm-ioctl-v1.h
	Now we are free to change dev_t in any way we want - on all boundaries
we have explicit conversions.
	Took __kernel_dev_t definition to linux/types.h and changed it with
__u16.  We are ready to proceed to 32bit now.

	Added old_encode_dev()/old_decode_dev() in CODA code - on assignments
to/from ->va_rdev.

	Added old_encode_dev() in loop.c

	Changed sys_mknod() prototype to have unsigned int passed to it
instead of current dev_t.  Added old_decode_dev() in sys_mknod() and
made sure that its callers are passing it old_encode_dev(<value>)
	Switched sys_ustat() and its variants from dev_t to unsigned (and
added old_decode_dev()).
	Took care of assignments to ROOT_DEV - again, old_decode_dev().
	Late-boot search in devfs (call sys_newstat() and compare with
st_rdev) also updated.

	Added old_encode_dev()/old_decode_dev() in dm-ioctl-*.c

	Minor cleanups in md.c + added old_decode_dev() on ioctl argument in
there.

	Minor cleanup of jffs2 fill_super.

	Added missing old_encode_dev() in JFS.

	NFS made dev_t-agnostic.  Aside of minor fixes in debugging printks,
and adding old_encode_dev()/old_decode_dev(), the main part is in handling
of exports with large dev_t.  New fhandle format introduced, fh_verify(),
fh_compose() and exports cache taught to deal with it.  Format is used when
->s_dev of exported fs doesn't fit into 256:256; in that case we put major
and minor in separate words in fhandle; ->fh_fsid_type is set to 2.

	tty->device had been used only in a couple of places and can be
calculated by tty->index and tty->driver.  Field removed, its users switched
to static inline dev_t tty_devnum(tty).

	sanitized dev_t use in debugging printks in XFS, switched their
bhash to use of struct block_device, added old_encode_dev() in XFS statfs()
(it had stored dev_t in ->fs_id[0])

	added old_encode_dev() in drm debugging printks, so they won't change
when we go for bigger dev_t.

	fs/reiserfs/procfs.c made sane.  It used to store dev_t of filesystem
in the proc_dir_entry->data (which is void *) and played very odd games after
that.
	Switched to seq_file, stores pointer to superblock, uses sget() to
validate it, avoids use of dev_t completely.

K8 can run with a 32bit kernel too.  If that's the case we have to tell
user space about it.  Remove the unneeded ifdef.

In that case the CPU is called "x86-64/hammer" even on 32bit.  This is
not strictly true on i386, but it's the named used by the current
oprofile user space for K8 performance counters and it would complicate
things to use different names between 32bit and 64bit.
