Commiteb9299bead("ACPI: EC: Use a spin lock without disabing interrupts") introduced an unexpected user-visible change in behavior, which is a significant CPU load increase when the EC is in use. This most likely happens due to increased spinlock contention and so reducing this effect would require a major rework of the EC driver locking. There is no time for this in the current cycle, so revert commiteb9299bead.
