To prepare kbuild for more kernel packaging formats move all packaging support
to scripts/package.

In top-level Makefile introduce generic support for all package formats using
target names *-pkg.  Included the old rpm target for backward compatibility.

A new variable KBUILD_IMAGE is used to specify what kernel image will be part
of the final package, and is to be set by the arch specific makefile.
KBUILD_IMAGE may be overridden from command line or environment.  KBUILD_IMAGE
will see wider usage later, mainly when installing kernel images.

Introducing KBUILD_IMAGE allowed arch specific details to be deleted from the
mkspec and builddeb scripts.

While in the process added the deb packet format.  Script is From: Wichert
Akkerman <wichert@wiggy.net>

To create a RPM packet use 'make rpm-pkg'.
To create a deb packet use 'make deb-pkg'.
Both targets are included in 'make help'

This patch three issues in NUMA API

- When 1 was passed to set_mempolicy or mbind as maxnodes argument
  get_nodes could corrupt the stack and cause a crash.  Fix that.

- Remove the restriction to do interleaving only for order 0.  Together
  with the patch that went in previously to use interleaving policy at boot
  time this should give back the original behaviour of distributing the big
  hash tables.

- Fix some bad white space in comments

With preallocation turned on, reiserfs_allocate_blocks_for_region wasn't
sending a large enough array to hold all the blocks it was asking the block
allocator to find.  This can result in stack corruption.

The fix is to kmalloc an array to hold the blocks, making sure to allocate
something large enough.

There was also a recent optimization to force the allocator to find a free
region large enough to hold the entire preallocation size.  This was
sometimes causing more blocks to be allocated then had been requested,
which would also overflow the array.  Something more elegant is required
here, until then just disable the optimization.

This is a big update for the tuner and tda9887 modules which are used for TV
card tuning.

The tda9887 module is basically completely rewritten and understands all the
config bits now instead of having just some fixed config presets.  Some of
these config bits can be changed by insmod options now.

The other big change is that both modules allow to use the V4L2 API for
inter-module communication (i.e.  when bttv/saa7134/...  pass through the
tuning ioctls to the modules).  That allows to specify the TV norm more
precisely (not just PAL but PAL-I, PAL-BG, ...), which is needed in some cases
to make TV audio work correctly.  Using the old v4l1 API is still possible so
this shouldn't break any users of these two modules.

This patch is from James, I've changed it slightly only.

The problem is that some IOMMU implementations have a maximum limit to the
size of the number of contiguously mappable pages (admittedly, this limit
is mostly in the resource management algorithms rather than the IOMMUs
themselves).

This patch adds this concept to the bio layer via the parameter

BIO_VMERGE_MAX_SIZE

which architectures can define in asm/io.h (if undefined, we assume it to
be infinite, which is current behaviour).

While adding this, I noticed several places where bio was making incorrect
assumptions about virtual mergeability (none of which was a bug: bio was
overestimating rather than underestimating).

- The worst offender was bio_add_page(), which seemed never to check for
  virtual mergeability

- I also fixed blk_hw_contig_segments() not to check the QUEUE_CLUSTER
  flag, and not to check the phys segment boundary.

In order to track the hw segment size across bios, I had to introduce two
extra bio parameters: bi_hw_front_size and bi_hw_back_size which store the
sizes of the front and back hw contiguous segments (and which will be equal
if there's only one hw segment).  When the bio is merged into a request,
these fields are updated with the total hw contig size so they can always
be used to assess if the merger would violate the BIO_VMERGE_MAX_SIZE
parameter.

I would also recommend BK-renaming all four files

This patch adds a new driver for the OmniVision OV6xx0 and OV7xx0 series of
CMOS image sensors.  It is currently used by the w9968cf USB webcam driver,
which is already in mainline 2.6.  Up until now it had to be compiled
outside the kernel tree, which is clearly suboptimal.

It is also used by version 2 of the ov511 USB webcam driver, which will be
merged in the near future.  That will reduce some code duplication, since
the existing ov511 has much of this code built-in.

This was previously submitted to Linux-USB-Devel, and I have fixed the
concerns that came up at that time.
