to use the crtc gamma_store directly instead of duplicating that
info locally.

Code stolen from gma500.
This is just a minor bit of safety code that I spotted and figured it
might be useful if we put it into the core. This is to make the
get_gamma ioctl reflect likely reality even before the first set_gamma
ioctl call.

Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.
Maybe this helps to encourage driver maintainers to do the switch.

Now that CRTC's have a primary plane, there's no need to track the
framebuffer in the CRTC. Replace all references to the CRTC fb with the
primary plane's fb.
This patch was generated by the Coccinelle semantic patching tool using
the following rules:

The internal crtc cursor gem object pointer was never set/updated since
it was required to be set in the first place.
Fixing this will make the pin/unpin count match and prevent cursor
objects from leaking when userspace drops all references to it. Also
make sure we drop the gem obj reference on failure.
This patch only affects Poulsbo chips.

The framebuffer needs to be unpinned in the crtc->disable callback
because of previous pinning in psb_intel_pipe_set_base(). This will fix
a memory leak where the framebuffer was released but not unpinned
properly. This patch only affects Poulsbo.

[this one ideally should make 3.6 - it fixes the very annoying mode setting bug]
This causes the pipe to be forced off prior to initial mode set, which
roughly mirrors the behavior of the i915 driver. It fixes initial mode
setting on my Intel DN2800MT (Cedarview) board. Without it, mode
setting triggers an out-of-range error from the monitor for most modes,
but only on initial configuration (i.e. they can be configured
successfully from userspace after that).

Poulsbo needs a physical address in the cursor base register. We allocate a
stolen memory buffer and copy the cursor image provided by userspace into it.
When/If we get our own userspace driver we can map this stolen memory directly.

requirement.

This provides the specific code for Poulsbo, some of which is also used for
the later chipsets. We support the GTT, the 2D engine (for console), and
the display setup/management. We do not support 3D or the video overlays.
In theory enough public info is available to do the video overlay work
but that represents a large task.
Framebuffer X will run nicely with this but do *NOT* use the VESA X
server at the same time as KMS. With a Dell mini 10 things like Xfce4 are
nice and usable even when compositing as the CPU has a good path to the
memory.
