cb->atapi.cdb is an array of 16 u8 elements. The call too memset()
would set the first part of the sge array to zero as well. It's not
a packed struct.
This one has been around for five years. I found it with Smatch. I
think the reason no one has seen it before is because we normally call
sil24_fill_sg() and that overwrites sge with proper information?

So when we added output polling, we'd suddenly use this code more often, and the fact that it always takes over crtc2 and messes with it during probing isn't what we really want to be happening. A more complete fix would to change it to use whatever crtc was free at the time, but for now lets stay simple and just don't poll if crtc2 is already in use.
Although a more correct fix was found I suspect we should do this as well, until we get a chance to readdres the tv out polling issues.

We really don't want to be polling tv-out but since we weren't forcing the
i2c lines to invalid (tv-out has no DDC), we were adding tv connectors to the
polling setup and this was causing blinking on secondary displays.

The vddc value in the power tables is not an actual voltage
like on discrete r6xx/r7xx/evergreen systems, but instead has
a symbolic meaning (e.g., NONE, LOW, HIGH, etc.). See atombios.h
Most RS780/RS880 vbioses don't have a SetVoltage table anyway,
so it shouldn't be doing anything to the hardware at the moment.
I need to figure out how voltage is supposed to work on the newer
IGPs; until then, disable it.

This adds an additional profile, mid, to the pm profile
code which takes the place of the old low profile. The default
behavior remains the same, e.g., auto profile now selects between
mid and high profiles based on power source, however, you can now
manually force the low profile which was previously only available
as a dpms off state. Enabling the low profile when the displays
are on has been known to cause display corruption in some cases.

This is needed to enable accel in the ddx. However,
due to a bug in older versions of the ddx, it relies
on accel being disabled in order to load properly on
evergreen chips. To maintain compatility, we add a new
get accel param and call that from the ddx. The old one
always returns false for evergreen cards.

PM attemps to unmap objects that aren't actually mapped into userspace ever,
so just don't bother unmapping them at this point, since all you are doing
is nothing. We should be making sure all access to these objects are locked in
kernel space instead. In theory the VRAM gart table is already done, and both
the shaders and stolen vga memory blocks are never accessed at runtime.

Commit 96d60303fd (ahci: Turn off DMA engines when there's no device)
implemented stopping DMA engines on empty ports but it used single
sampling of status registers to determine device presence which led to
disabling of DMA engines on occupied ports. Do it after all EH
actions are complete using device presence state determined by EH.
This avoids spurious disabling of DMA engines and simplifies the code.
