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.

This patch defines a macro that does exactly what
wait_event_interruptible() does except that it adds the current task to the
wait queue as an exclusive task (i.e., sets the WQ_FLAG_EXCLUSIVE flag)
rather than as a non-exclusive task as wait_event_interruptible() does.

This allows one to do a wake_up_nr() to wake up a specific number of tasks.

Cleanup arch/i386/kernel/setup.c a little bit by:

* un-inlining machine_specific_memory_setup() (it's implementations are
  pretty big to be inlined anyway)

* remove setup_memory_region() by moving the code inside setup_arch()

I would also recommend BK-renaming all four files
(include/asm-i386/*/setup_arch_post.h) to ".c" and moving them into
arch/i386/*/, but that obviously is not needed in anyway.  But IMHO they
are clearly ".c" files, not ".h" 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.

People like to use swapoff/swapon as a way of restoring their VM to a
predictable "preconditional" state.

Problem is, swapoff leaves mapped anon/pagecache pages on the inactive list,
so they immediately get swapped out again when swapspace becomes available.

This patch adds support for the O_NOATIME open flag (GNU extension):

int O_NOATIME  	Macro
  If this bit is set, read will not update the access time of the file.
  See File Times. This is used by programs that do backups, so that
  backing a file up does not count as reading it. Only the owner of the
  file or the superuser may use this bit.

It is useful if you want to do something with the file atime (for instance,
moving files that have not been accessed in a while to somewhere else, or
something like Debian's popularity-contest) but you also want to read all
files periodically (for instance, tripwire or debsums).

Currently, the program that reads all files periodically has to use utimes,
which can race with the atime update:

    A               B
  open
  fstat
  read
                  open
                  read
                  close
  close
  utimes

And the file still has the old atime, instead of the new one from when B
did the read from it.  This problem does not happen if A uses O_NOATIME
instead of utimes to preserve the atime.

This patch adds the O_NOATIME constant for all architectures, but it would
also be possible to add it one architecture at a time by defining it to 0
when not defined in asm-*.

Here's a patch to allocate memory for big system hash tables with the
bootmem allocator rather than with main page allocator.

It is needed for three reasons:

(1) So that the size can be bigger than MAX_ORDER.  IBM have done some
    testing on their big PPC64 systems (64GB of RAM) with linux-2.4 and found
    that they get better performance if the sizes of the inode cache hash,
    dentry cache hash, buffer head hash and page cache hash are increased
    beyond MAX_ORDER (order 11).

     Now the main allocator can't allocate anything larger than MAX_ORDER, but
     the bootmem allocator can.

     In 2.6 it appears that only the inode and dentry hashes remain of those
     four, but there are other hash tables that could use this service.

(2) Changing MAX_ORDER appears to have a number of effects beyond just
    limiting the maximum size that can be allocated in one go.

(3) Should someone want a hash table in which each bucket isn't a power of
    two in size, memory will be wasted as the chunk of memory allocated will
    be a power of two in size (to hold a power of two number of buckets).

    On the other hand, using the bootmem allocator means the allocation
    will only take up sufficient pages to hold it, rather than the next power
    of two up.

    Admittedly, this point doesn't apply to the dentry and inode hashes,
    but it might to another hash table that might want to use this service.


I've coelesced the meat of the inode and dentry allocation routines into
one such routine in mm/page_alloc.c that the the respective initialisation
functions now call before mem_init() is called.

This routine gets it's approximation of memory size by counting up the
ZONE_NORMAL and ZONE_DMA pages (and ZONE_HIGHMEM if requested) in all the
nodes passed to the main allocator by paging_init() (or wherever the arch
does it).  It does not use max_low_pfn as that doesn't seem to be available
on all archs, and it doesn't use num_physpages since that includes highmem
pages not available to the kernel for allocating data structures upon -
which may not be appropriate when calculating hash table size.

On the off chance that the size of each hash bucket may not be exactly a
power of two, the routine will only allocate as many pages as is necessary
to ensure that the number of buckets is exactly a power of two, rather than
allocating the smallest power-of-two sized chunk of memory that will hold
the same array of buckets.

The maximum size of any single hash table is given by
MAX_SYS_HASH_TABLE_ORDER, as is now defined in linux/mmzone.h.

This patch creates and exports 2 functions which can be used by the rest of

- dmi_check_system() function checks system DMI data against given blacklist
  table and on each match runs corresponding callback function;

- dmi_get_system_info() function returns DMI data value.  Useful for people
  wanting more complex DMI data check than simple string match.

Also filling unused match entries with NO_MATCH made optional, but existing
NO_MATCH occurences are left intact, so people are free to continue dmi_scan.c
