Subject: drm/radeon: use system_wq instead of dev_priv->wq
X-Git-Tag: v2.6.38-rc1~419^2~8
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=32c87fca2fac490e34a9fa900b45f2fbb4faacf9;p=pandora-kernel.git

drm/radeon: use system_wq instead of dev_priv->wq

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.
