Missing #include

Update the ioctl32 handlers for the 64-bit architectures to recognize
the new Device-Mapper version 4 ioctls. The version 1 ioctls are still
there.  If/When the version 1 ioctls are removed, these same files
will need to be updated again.

I have been unable to test this patch yet, since I have not had any
luck getting 2.6.0-test2 to compile on my ppc64 box (not a dm-related
problem).  But the patch is pretty trivial, so I'm pretty confident it
will work. If anyone else can test this (on mips64, sparc64, parisc,
or x86-64), let me know if you have any problems.  [Kevin Corry]

The 2.4 version of Device-Mapper scans for device-numbers in decimal
instead of hex (in dm_get_device()). Update 2.6 so both versions use
the same behavior.  [Kevin Corry]

Work around gcc-2.9x token-pasting bug by adding a space in front of the
comma.

 * the usual pile of tv card database updates.
 * various signed/unsigned fixups (fix gcc 3.3 warnings)
   and releated cleanups (use ARRAY_SIZE macro, ...).
 * moved some code which can be shared with the new,
   upcoming cx2388x driver to a separate module.
 * split the irq handler into smaller functions.
 * some new features (field rate capture support for example).
 * simplified i2c code a bit by removing redundant
   bookkeeping of attached i2c clients.
 * merged i2c changes back into my tree, there are some no-op
   changes due to this.
 * various other bugfixes.
 * fix build failure with CONFIG_FW_LOADER enabled

This patch drops procfs code from videodev.c and adds sysfs support
instead.  It adds a new class where all v4l devices are listed.  It
also provides some new helper functions for v4l drivers.

Original patch from Erik Andersen <andersen@codepoet.org>:
- fix CONFIG_IDEDISK_STROKE by adding proper detection of HPA feature set
  and removing IDE_STROKE_LIMIT
- remove irrelevant idedisk_supports_host_protected_area()
- make the HPA detection actually display useful information

I've reworked it a bit:
- detect HPA before calculating drive's geometry
- move HPA detection outside init_idedisk_capacity()
  to idedisk_check_hpa_lba28() and idedisk_check_hpa_lba48()
- use sectors_to_MB()
- respect 80-column limit

- no need to zero drive->capacity48 and drive->select.b.lba
- don't call idedisk_read_native_max_address_ext() twice
  if drive uses LBA-48 and CONFIG_IDEDISK_STROKE is defined
- remove uneccessary setup of drive->capacity48/cyl/select.b.lba
  if drive uses LBA-48, maximum virtual LBA address needs to be set
  and CONFIG_IDEDISK_STROKE is defined
- set drive->cyl only once if drive uses LBA-48
- don't call idedisk_read_native_max_address() if drive uses LBA-48
  and don't call it twice if CONFIG_IDEDISK_STROKE is defined
- don't check for Host Protected Area if drive uses CHS addressing
  (such combination is not supported by a driver)
- remove duplicated code (at the end of the function) that is never executed

From Andries.Brouwer@cwi.nl:

- store capacities in sector_t
- add generic sectors_to_MB() helper to ide-disk.c
- fix drive->bios_cyls calculation (limiting it to 65535) for disks

From Andries.Brouwer@cwi.nl:

- these functions should return 0 not 1 on error

From Benjamin Herrenschmidt <benh@kernel.crashing.org>.

- avoid device list corruption and scheduling at interrupt time
  (more work needed on proper locking)
- make sure "hold" flag and ide_dma_queued_* ops are properly
  transferred from old to new interface

From Andrey Borzenkov <arvidjaar@mail.ru>:

Apparently drive->driver is never NULL now but defaults to the default driver.

fixes kobject_register() oops

Now that we properly track queue references, that showed a bug in
scsi_ioctl.c, where it was dropping queues that it had never properly
gotten in the first place.

To be able to properly be able to keep references to block queues,
we make blk_init_queue() return the queue that it initialized, and
let it be independently allocated and then cleaned up on the last
reference.

I have grepped high and low, and there really shouldn't be any broken
uses of blk_init_queue() in the kernel drivers left.  The added bonus
being blk_init_queue() error checking is explicit now, most of the
drivers were broken in this regard (even IDE/SCSI).

No drivers have embedded request queue structures. Drivers that don't
use blk_init_queue() but blk_queue_make_request(), should allocate the
queue with blk_alloc_queue(gfp_mask). I've converted all of them to do
that, too. They can call blk_cleanup_queue() now too, using the define
blk_put_queue() is probably cleaner though.

This patch fixes the BIO_RW_AHEAD being tested at the wrong end
in the bio layer.

The problem with PF_READAHEAD is that if someone does a non-GFP_ATOMIC memory
allocation we can enter page reclaim and then call writepage, while
PF_READAHEAD is set.  The block layer then drops writes or the wrong reads on
the floor.  It can cause data loss.

A fix is complex (well, intrusive).  Given that the readahead code is now
skipping the entire readahead attempt if the queue is congested, the setting
of PF_READAHEAD probably is not doing anything useful anyway, so simply
remove it.

There seemed to be increase in Athlon users reporting MCEs in 2.6 that
they never saw in 2.4 and I didn't buy the "2.6 pushes hardware harder"
for a second given folks are running 2.4+preempt+O(1) etc patchkits
without problems.

So I did a mini-audit of the mcheck code.

How embarressing. Another fix that went into 2.4 that never made
it forward. Once I'm done with various Red Hat administrivia
I'll see if I can devote some time to going through the changesets
mailing list. I wonder just how many other really stupid bugs
like this got fixed and not brought forward.

In order to properly track down who needs to program the IRQ MUX
register, add the subsystem vendor and device IDs to the kernel
message indicating discovery of the cardbus bridge.

The IRQ steering code operates too early at present, and actually
prevents us detecting ISA interrupts.

We should not touch the IRQ MUX register on TI bridges - only the
machine itself knows the right value for this.  The kernel doesn't
have the knowledge to know what function the cardbus controllers
multi-function pins have been assigned by the hardware manufacturer.

Currently, yenta does not try to clean up after an error occurs while
initialising a cardbus socket.  This cset ensures that we release
resources.  We also claim the cardbus MMIO memory resource.

pnp_x_valid returns 1 if valid.  Therefore we should be using
!pnp_port_valid.  Also cleans up some formatting issues.

Convert X.25 async driver to have dynamic net_device's.
This driver is a lot like SLIP so the code changes were similar.  
        - Added similar locking to SLIP
        - replaced code that snooped for MTU changes with the
          net_device change mtu callback.
        - cleaned up the statistics by using the net_device_stats structure.

Patch is against 2.6.0-test2.

Not sure if anyone ever uses this.  I tested by bringing up an x.25 async
line using a modified version of slattach.

The conversion from cli/sti to locking in X.25 must not have been tested
on a real SMP with memory debugging enabled.  It OOPS right away if
I do:
        modprobe x25; ifconfig -a

The problem is that it dereferences the socket after it has already been
freed.  The fix for this is to make the call to sock_put, later in
x25_destroy_socket do the free.  Also, need a go to avoid references
in x25_release.

This patch is against 2.6.0-test2.  The problem is that the ax25_destroy_socket
function frees the socket buffer, but then ax25_release dereferences this causing
an OOPS.  To reproduce:
        modprobe ax25; ifconfig -a

Replaced sk_free with sock_put which will free if this is the last reference.

The existing ROSE /proc interface has no module owner, and doesn't check for
bounds overflow.  Easier to just convert it to the seq_file wrapper functions.

This patch is against 2.6.0-test2 (offsets assume earlier patch).

This patch changes the ROSE protocol to allocate an array of pointers and each network device
separately.  This sets up later change where network_device object's are released on last use
which may be after the module is unloaded.

The patch is against 2.6.0-test2 (though this code hasn't changed in a long time).


Allocation is done via alloc_netdev so the dev->priv area is already reserved and
doesn't need to be allocated separately. 

When a dead detached thread has been temporarily zombified because it's
ptraced and its tracer tries to reap it, it deadlocks on SMP.

Here's the fix.

A recent patch changed the rpc/*/channel files to behave
differently depending on whether they were open for read or not.

This hadn't been tested thoroughly.  The cache_reader structure
that was now only allocated when opening for read, had a field that
was iused when writing.

This patch removes that field and takes a different approach to solving
the issue it addressed.

And it has been tested a bit better.
