+Subject: [PATCH 254/323] drm/i915/gt: Only disable interrupts for the timeline
+ lock on !force-threaded
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+According to commit
+    d67739268cf0e ("drm/i915/gt: Mark up the nested engine-pm timeline lock as irqsafe")
+
+the intrrupts are disabled the code may be called from an interrupt
+handler and from preemptible context.
+With `force_irqthreads' set the timeline mutex is never observed in IRQ
+context so it is not neede to disable interrupts.
+
+Disable only interrupts if not in `force_irqthreads' mode.
