[PATCH v5 0/6] drm/i915: Most fixes to make i915 work well with PREEMPT_RT.

[Maarten Lankhorst <dev@lankhorst.se>]

This series has dropped 'drm/i915/gt: Use signalers_lock to prevent
starvation of irq_work.', but otherwise includes all fixes I have 
created so far to make the core i915 module work correctly on
PREEMPT_RT.

I'm hoping by reducing the delta, the remaining patches will become
easier to review and accept. A major patch series with nearly 30 patches
over the entire code is harder to review and accept than a few isolated
series targeting specific parts of the driver.

Maarten Lankhorst (3):
  drm/i915/gt: Fix selftests on PREEMPT_RT
  drm/i915/gt: Set stop_timeout() correctly on PREEMPT-RT
  drm/i915: Use sleeping selftests for igt_atomic on PREEMPT_RT

Sebastian Andrzej Siewior (3):
  drm/i915/gt: Use spin_lock_irq() instead of local_irq_disable() +
    spin_lock()
  drm/i915: Drop the irqs_disabled() check
  drm/i915/guc: Consider also RCU depth in busy loop.
