linuxkpi: Mitigate a seqlock livelock
Disable preemption in seqlock write sections when using the _irqsave
variant. This ensures that a writer can't be preempted and subsequently
starved by a reader running in a callout handler on the same CPU.
This fixes occasional display hangs seen when using the i915 driver.
