there is no longer a reference to struct msi_msg. The MSI code

The attached patch adds a capability flag that allows an application
to determine whether a particular device can handle "second generation
modulation" transponders. This is necessary in order for applications
to be able to decide which device to use for a given channel in
a multi device environment, where DVB-S and DVB-S2 devices are mixed.
It is assumed that a device capable of handling "second generation
modulation" can implicitly handle "first generation modulation".
The flag is not named anything with DVBS2 in order to allow its
use with future DVBT2 devices as well (should they ever come).

instead of ID.
Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.
Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.
Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

Add flag value UPF_FIXED_TYPE which specifies that the UART type is
known and should not be probed. For this case the UARTs properties
are just copied out of the uart_config entry.
This allows us to keep SOC specific 8250 probe code out of 8250.c. In
this case we know the serial hardware will not be changing as it is on
the same silicon as the CPU, and we can specify it with certainty in
the board/cpu setup code.
The alternative is to load up 8250.c with a bunch of OCTEON specific
special cases in the probing code.

In order to use Cavium OCTEON specific serial i/o drivers, we first
patch the 8250 driver to use replaceable I/O functions. Compatible
I/O functions are added for existing iotypeS.
An added benefit of this change is that it makes it easy to factor
some of the existing special cases out to board/SOC specific support
code.
The alternative is to load up 8250.c with a bunch of OCTEON specific
iotype code and bug work-arounds.

Move the tty_port and uart_info bits around a little. By embedding the uart_info
into the uart_port we get rid of lots of corner case testing and also get the
ability to go port<->state<->info which is a bit more elegant than the current
data structures.
Downsides - we allocate a tiny bit more memory for unused ports, upside we've
removed as much code as it saved for most users..

In the commit below a new struct serial_rs485 was introduced for a new
ioctl:
commit c26c56c0f40e200e61d1390629c806f6adaffbcc
Author: Alan Cox <alan@redhat.com>
Date: Mon Oct 13 10:37:48 2008 +0100
tty: Cris has a nice RS485 ioctl so we should steal it
This structure uses the __u32 types for some of its members, which leads
to the following compile error:
$ cc -I.../include -c X.c
In file included from X.c:2: .../include/linux/serial.h:185:
error: expected specifier-qualifier-list before ‘__u32’
$
It seems that these types are appropriate for this structure as it is
to be exposed to userspace. These types are available via linux/types.h
so move the include of that outside the __KERNEL__ section.
