With cmwq, there's no reason for radeon to use a dedicated workqueue.
Drop dev_priv->wq and use system_wq instead.

Because radeon_driver_irq_uninstall_kms() may be called from
unsleepable context, the work items can't be flushed from there.
Instead, init and flush from radeon_irq_kms_init/fini().

While at it, simplify canceling/flushing of rdev->pm.dynpm_idle_work.
Always initialize and sync cancel instead of being unnecessarily smart
about it.

The CMASK RAM is for colorbuffer compression (used in conjunction
with MSAA). Only one user (filp) can access it.

The CMASK RAM access is managed in the same way as Hyper-Z, but there is
a separate ioctl, because an app that uses MSAA does not necessarily
have to use zbuffering.

Acer laptop (TravelMate 5730G) has an HDMI connector
on the laptop and a DVI connector on the docking station
and both share the same encoder, hpd pin, and ddc line.
The bios connector table reflects this and is technically
correct, however, we drop the DVI connector here since
xrandr has no concept of encoders (only crtcs and connectors)
and will try and drive both connectors with different crtcs
which isn't possible on the hardware side and leaves no crtcs
for LVDS or VGA.

We need to track the state of the switch in drivers, so that after s/r

don't allow a userspace open to occur if we've switched the gpu off.

On resume, we were attemping to unblank the displays before the

For the fbdev api if the struct fb_var_screeninfo accel_flags field is set
to FB_ACCELF_TEXT then userland applications can not mmap the mmio region.
Since it is a bad idea for DRM drivers to expose the mmio region via the
fbdev layer we always set the accel_flags to prevent this. Please apply.
