This board has some special tea5767 configuration. Basically, radio 
XTAL uses a different frequency than the other supported radios. It 
uses a 13 MHz XTAL.

This patch adds the proper radio gpio and tea5767 configurations for 
the board.

Also, with PAL/BG, the board requires some special init for tda9887:
port1=0 port2=0 qss=1

Thanks to Serge Kolotylo and MIDImaster for their help on identifying 
the proper needs for this driver.

tea5767 has several possible configurations. Before the patch, the
driver were assuming the more common configuration. However, some newer
cards, like MSI @nyware Master requires other configurations, like
de-activating a gpio port and changing chip Xtal.

This patch adds the capability of altering device configuration at
runtime. This may also be used later to activate some features like
auto-mute when signal is weak.
Signed-off-by: NMauro Carvalho Chehab <mchehab@infradead.org>

Currently, the only tuner-specific device that allows special
configurations is tda9887. However, tea5767 also may require some
special configurations (for example, to specify a different Xtal freq).

This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl
(TUNER_SET_CONFIG). The newer one allows specifying what tuner is
appliable to a configuration set, and allows an arbitrary configuration
struct.

This can be broken down into these major areas:
 - Documentation updates (language translations and fixes, as
   well as kobject and kset documenatation updates.)
 - major kset/kobject/ktype rework and fixes.  This cleans up the
   kset and kobject and ktype relationship and architecture,
   making sense of things now, and good documenation and samples
   are provided for others to use.  Also the attributes for
   kobjects are much easier to handle now.  This cleaned up a LOT
   of code all through the kernel, making kobjects easier to use
   if you want to.
 - struct bus_type has been reworked to now handle the lifetime
   rules properly, as the kobject is properly dynamic.
 - struct driver has also been reworked, and now the lifetime
   issues are resolved.
 - the block subsystem has been converted to use struct device
   now, and not "raw" kobjects.  This patch has been in the -mm
   tree for over a year now, and finally all the issues are
   worked out with it.  Older distros now properly work with new
   kernels, and no userspace updates are needed at all.
 - nozomi driver is added.  This has also been in -mm for a long
   time, and many people have asked for it to go in.  It is now
   in good enough shape to do so.
 - lots of class_device conversions to use struct device instead.
   The tree is almost all cleaned up now, only SCSI and IB is the
   remaining code to fix up...

If the node we're booting on doesn't have memory, bootstrapping kmalloc()
caches resorts to fallback_alloc() which requires ->nodelists set for all
nodes.  Fix that by calling set_up_list3s() for CACHE_CACHE in
kmem_cache_init().

As kmem_getpages() is called with GFP_THISNODE set, this used to work before
because of breakage in 2.6.22 and before with GFP_THISNODE returning pages from
the wrong node if a node had no memory. So it may have worked accidentally and
in an unsafe manner because the pages would have been associated with the wrong
node which could trigger bug ons and locking troubles.

This patch allows gfs2 to perform journal recovery even if it is mounted
read-only. Strictly speaking, a read-only mount should not be writing to
the filesystem, but we do this only to perform journal recovery. A
read-only mount will fail if we don't recover the dirty journal. Also,
when gfs2 is used as a root filesystem, it will be mounted read-only
before being mounted read-write during the boot sequence. A failed
read-only mount will panic the machine during bootup.

There was a bug in the truncation/invalidation race path for
->page_mkwrite for gfs2. It ought to return 0 so that the effect is the
same as if the page was truncated at any of the other points at which
the page_lock is dropped. This will result in the restart of the whole
page fault path. If it was due to a real truncation (as opposed to an
invalidate because we let a glock go) then the ->fault path will pick
that up when it gets called again.

This is a small I/O performance enhancement to gfs2.  (Actually, it is a rework of
an earlier version I got wrong).  The idea here is to check if the write extends
past the last block in the file.  If so, the function can save itself a lot of
time and trouble because it knows an allocate will be required.  Benchmarks like
iozone should see better performance.

This patch removes a vestigial variable "i_spin" from the gfs2_inode
structure.  This not only saves us memory (>300000 of these in memory
for the oom test) it also saves us time because we don't have to
spend time initializing it (i.e. slightly better performance).

It is possible to reduce the size of GFS2 inodes by taking the i_alloc
structure out of the gfs2_inode. This patch allocates the i_alloc
structure whenever its needed, and frees it afterward. This decreases
the amount of low memory we use at the expense of requiring a memory
allocation for each page or partial page that we write. A quick test
with postmark shows that the overhead is not measurable and I also note
that OCFS2 use the same approach.

In the future I'd like to solve the problem by shrinking down the size
of the members of the i_alloc structure, but for now, this reduces the
immediate problem of using too much low-memory on x86 and doesn't add
too much overhead.

Although the values were all being calculated correctly, there was a
race in the assert due to the way it was using atomic variables. This
changes the value we assert on so that we get the same effect by testing

This patch fixes a couple of problems which affected the execution of files
on GFS2. The first is that there was a corner case where inodes were not
always uptodate at the point at which permissions checks were being carried
out, this was resulting in refusal of execute permission, but only on the
first lookup, subsequent requests worked correctly. The second was a problem
relating to incorrect updating of file sizes which was introduced with the
write_begin/end code for GFS2 a little while back.
