The drm device drivers currently allow seeking on the
character device but never care about the actual
file position.
When we change the default llseek operation to be
no_llseek, calling llseek on a drm device would
return an error condition, which is an API change.
Explicitly setting noop_llseek lets us keep the
current API.

It is recommended that we use the Video BIOS tables that were copied
into the OpRegion during POST when initialising the driver. This saves
us from having to furtle around inside the ROM ourselves and possibly
allows the vBIOS to adjust the tables prior to initialisation.
On some systems, such as the Samsung N210, there is no accessible VBIOS
and the only means of finding the VBT is through the OpRegion.
v2: Rearrange the code so that ASLE is enabled along with ACPI
v3: Enable OpRegion parsing even without ACPI

All drivers happily copy&pasted the default implementation without
checking whether this callback is used at all. It's not. Sigh.
Kill it.

When trying to keep track of features between the kernel, the 2D driver,
mesa and the specs, it helps to list any other name by which the device
is referred to.

The original i965, including the revised G35 and Q35, requires an
alignment of 128K for the display surface with linear memory, so
increase the requirement from 64k for these chipsets. For the later
chipsets in the i965 family, only a 4k alignment is required. (So
long as we do not start performing asynchronous flips.)
Note the impact of this should be slight as on i965 we should be using a
tiled frontbuffer for anything up to a 4096x4096 display.
v2: compilation fixes and note that the docs do not exclude the G35 from
the extra alignment.

The active list and request list move into the ringbuffer structure,
so each can track its active objects in the order they are in that
ring. The flushing list does not, as it doesn't matter which ring
caused data to end up in the render cache. Objects gain a pointer to
the ring they are active on (if any).

The BSD ringbuffer support that is landing in this branch
significantly conflicts with the Ironlake PIPE_CONTROL fix on master,
and requires it to be tested successfully anyway.
