Emitting a warning is overkill in intel_setup_irq_remapping() since the interrupt remapping is pre-enabled. For example, there's no guarantee that kexec will explicitly disable interrupt remapping before booting a new kernel. As a result, users are seeing warning messages like below when they kexec boot a kernel, though there is nothing wrong: DMAR-IR: IRQ remapping was enabled on dmar18 but we are not in kdump mode DMAR-IR: IRQ remapping was enabled on dmar17 but we are not in kdump mode DMAR-IR: IRQ remapping was enabled on dmar16 but we are not in kdump mode ... ... Downgrade the severity of this message to avoid user confusion.
