Add support for the TI VLYNQ high-speed, serial and packetized bus.
This bus allows external devices to be connected to the System-on-Chip and
appear in the main system memory just like any memory mapped peripheral.
It is widely used in TI's networking and multimedia SoC, including the AR7
SoC.

The console blank timer is currently hardcoded to 10*60 seconds which
might be annoying on systems with no input devices attached to wake up the
console again. Especially during development, disabling the screen saver
can be handy - for example when debugging the root fs mount mechanism or
other scenarios where no userspace program could be started to do that at
runtime from userspace.
This patch defines a core_param for the variable in charge which allows
users to entirely disable the blank feature at boot time by setting it 0.
The value can still be overwritten at runtime using the standard ioctl
call - this just allows to conditionally change the default.

Add EISA IDs for Network Peripherals FDDI boards. Descriptions taken from

It's unlikely we'll ever support these cards, the problem being the lack
of documentation. Assuming the policy for the EISA ID database is the
same as for PCI I'm sending these entries for the sake of completeness.

Since videobuf-dma-contig is designed to handle physically contiguous
memory, this patch modifies the videobuf-dma-contig code to only accept a
user space pointer to physically contiguous memory. For now only
VM_PFNMAP vmas are supported, so forget hotplug.
On SuperH Mobile we use this with our sh_mobile_ceu_camera driver together
with various multimedia accelerator blocks that are exported to user space
using UIO. The UIO kernel code exports physically contiguous memory to
user space and lets the user space application mmap() this memory and pass
a pointer using the USERPTR interface for V4L2 zero copy operation.
With this approach we support zero copy capture, hardware scaling and
various forms of hardware encoding and decoding.

with VM_BUG_ON(). Callers that know their node is valid are then

it turns out we need to pass u64 instead of resource_size_t for that.

PIT_TICK_RATE is currently defined in four architectures, but in three
different places. While linux/timex.h is not the perfect place for it, it
is still a reasonable replacement for those drivers that traditionally use
asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency.
Note that for Alpha, the actual value changed from 1193182UL to 1193180UL.
This is unlikely to make a difference, and probably can only improve
accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE
a few years ago, after which every existing instance was getting changed
to 1193182. According to the specification, it should be
1193181.818181...

In the near future, the driver core is going to not allow direct access

dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
